Honeywell Inc is renowned for producing quality thermostats in all price range and has a wide range of capabilities in terms of the design and model. Whether you want a high-end sleek, touch-screen thermostat with self learning features or the simple manual thermostat, you have got a plethora of options to choose from. The choice of thermostat depends on the way our lifestyle is shaped and of course, the budget.

If you like sober thermostat model and are not a big fan of the technology or you stay at home for the major part of the day, then you can easily go for a non-programmable thermostat. This type of digital thermostat is pure bliss for people who just live simplicity.

It will save your time from programming, give you the liberty to change the temperature whenever you wish to and at the same time, it is an extremely cheap option, when compared to other thermostat models.

Here in this article, we will talk about a digital non-programmable thermostat from the house of Honeywell, named TL7235A1003.

TL7235A1003 is a double pole, 240 volt line thermostat designed exclusively for baseboard heaters, convectors and fan forced heaters. The contemporary design of this thermostat blends in perfectly with any wall decor.

You can set the temperature anywhere in the range of 40F to 86F. The push buttons on the from panel provide easy control over the process of setting the desired temperature. The clear, digital LCD display shows some vital information and can be back lit, whenever we want it to be.

Thanks to the DPST switch, the clicking noise is reduced which means a less noisy operation.

This was a small gist and overview  about the product, to know the different features in detail read on.

 

  • Design

 

Honeywell’s TL7235A1003 is built in a 4.875 in. x 2.75 in. x 0.875 in. (H×W×D) heavy duty package. It is quite sturdy and does not break easily. The front panel consist of a LCD screen three push buttons and an on/off toggle switch. The first two buttons are the UP/DOWN temperature adjustment buttons. These buttons have been indicated through an up-arrow at the top of the Up button and down-arrow at the bottom of the down button, which makes it easier to access without any confusion.  Pressing any of these two buttons, illuminates the LCD screen for 10 sec.

 

The third button controls the backlight. Once pressed, this would illuminate the LCD screen for 5 Sec. In case you just want to check on the temperature or any other parameters like time etc, but do not want to change the set temperature, this control button comes in handy.

The on/off toggle switch can be used to control the power supply to the heater. Setting it to “OFF” means you have cut the power to the heater.

 

 

  • Display

 

The LCD digital display of TLV7235A1003 thermostat is quiet informative and gives out clear concise details about the temperature and other important things. The backlight feature makes it readable in any lighting condition.

 

The main highlight of this display is the heating power indicator which tells you an approximate amount of energy consumed to maintain the set temperature. It has a total of 4 S-shaped bars. One such bar indicates 25% duty cycle approximate. This means, say if your thermostat shows 2 such bars, it indicates that the heater is running on a (25+25)50% approximate duty cycle.

This is a good way to get an idea about the maximum amount of energy being consumed for the set temperature.

Another beneficial feature is the heating indicator, which gives at a glance confirmation that the heat is on.

The display also shows temperature in Fahrenheit format. By default, the display shows the actual room temperature.

In case you want to have a look at the set temperature, press the up/down button placed at the front panel. The set point will flash on the screen for 5 sec.   

It also displays two error messages: “HI” and “LO”, in special cases. “HI” corresponds to the event when the room temperature goes beyond 122 F. The“LO” on the other hand, corresponds to the even when the room temperature is below 32F, which indicates that the heating must be activated.

The display resolution of the temperature is about 1F.

 

  • Temperature Precision

 

The set temperature of this non programmable unit can be adjusted in between 40F to 86F. It boats of maintaining temperature accuracy, owing to the electronic temperature controller used in it. The 1 degree temperature precision can help you save up to 10% on your energy bills.

 

 

  • Compatibility

 

TLV7235A1003 thermostat unit is designed to control the temperature of the resistive rated electric baseboard heaters, convectors, radiant ceiling heaters and fanforced heaters.

It is rated for 15 Amp at 240 Volts which means it can be used for loads only up to 3600Watt.

Not suitable for inductive loads.

 

 

  • Power Source

 

This thermostat from Honeywell is free from the hassle of battery changing and maintenance. It is wired directly to the 240V, 50-60Hz power source. So, you need not worry about the additional battery charges. It comes with 5,5in copper tinted lead wires for the connection.

 

The installation of this basic thermostat is quite easy and can be done by anyone who has had prior experience. However, if you are installing it for the first time, it would be safest to get a professional help.

 

  • Relay Sound

 

The DPST relay switch used in this thermostat unit maintains the clicking noise at minimum. This ensures a silent operation and hence can be set up at any room including the bedroom. The silent operation of the relay will not create hindrance to your sweet sleep.

Just for your quick reference below are the pros and cons of the Honeywell TLV7235A1003.

Pros:

  • Sturdy build
  • Sleek design blends with any wall decor
  • Easy push button for temperature and back light control
  • On demand illumination of the LCD screen
  • Indicator that shows the heating unit is ON
  • Indicator that shows how much duty cycle needed to maintain the desired temperature
  • UP/DOWN button also serve two other purpose: 1. To illuminate the screen for 10 sec 2. Flash the set temperature for 5 sec.
  • You can shut the heater off when not needed through the ON/OFF switch.  

Cons:

  • Sometimes the plastic between the relays heat up and alter the temperature, which in turn may affect the accuracy of the unit.
  • Cannot be used for inductive load and cooling system.

These were all the important features of this device you need to know. As already mentioned, if you are looking for a basic thermostat, this product is a great option to consider. Be it for a working at home professional, a retired person or anyone who is always in and around the house for the most of their time, it is obvious that you need not want to spend extra bucks for just changing the temperature when you can easily get it done manually.

In a nutshell, this unit is a simple yet efficient thermostat and aids reduction in the heating energy consumption and increase savings!   

If your home is having a single stage heating system (like a gas furnace) without any cooling function, you simply need a “heat only thermostat” to control the heating system. A heat only thermostat is designed to perform the basic function of regulating room temperature by controlling the heating system (be it a single stage furnace or a heat pump). Usually, a basic heat only thermostat will be having only two switch controls – 1) an On/Off switch and 2) temperature adjustment buttons.

When put to “ON” position or “Heat” position (some thermostats mark ‘On’ as ‘Heat’), the thermostat will turn ON the furnace/heating system and keep it active until the set temperature is achieved. The ‘adjustment buttons’ can be used to increase/decrease temperature to your desired level.

There will be only 2 terminals for a heat only thermostat, marked ‘R’ and ‘W’. You only need to make two connections between your heating system and the thermostat.

Note 1: Some single stage heating systems have a fan to distribute heat faster. For such systems, heat only thermostats with fan switch option is available. These thermostats will have 3 terminals usually, marked ‘R’ , ‘W’ and ‘G’; where ‘G’ terminal is to connect fan of the furnace.

Note 2: Heat only thermostats are also known as ‘2 wire thermostats’. You may read our guide on 2 wire thermostats, which also covers 2 wire single pole thermostats for line voltage systems.

Heat Only Thermostats

Now let’s see all the popular ‘heat only thermostat’ models out there. As mentioned above, a heat only thermostat is basically a 2 wire thermostat with two terminals ‘R’ and ‘W’, which is suitable to regulate a single stage heating system (without any cooling option).

Note: To regulate a single stage heating system, you can actually use any thermostat that supports single stage wiring. For example, Smart thermostats like Nest, Ecobee, and WiFi thermostats like Honeywell RTH9585WF, Emerson Sensi – all supports single stage wiring. You just need to connect the ‘R’ and ‘W’ terminals of these thermostats, and leave all other terminals not connected. So if you want a technologically advanced thermostat with smart features, internet connectivity and smartphone based control, you better choose one above rather than a basic heat only thermostat.

#1 Honeywell TH1100DV1000 Heat Only Thermostat

This is a basic heat only thermostat model from Honeywell, with temperature range 40 deg F to 90 deg F to choose from. It has only 3 buttons, an Off/Heat button on the side and an up/down button on the front to adjust temperature range.  This model has a square shaped, backlit LCD display, which displays temperature in an easy to read format. TH1100DV also provides compressor protection feature for the heating system.

If you’re using this model in garage, a mode is available where temperature can be ranged from 35 deg F to 90 deg F.

#2 Emerson 1E78 Heat Only Thermostat

1E78-140 is one of the best selling non programmable heat only thermostat from Emerson. This model is compatible to be used with single stage heat only systems, single stage heat pump and milli volt systems. The display is rectangle shaped LCD, with a back light.

1E78 is designed in such a way as a perfect upgrade to an old mechanical thermostat. The body is designed to cover any wall markings by a mechanical thermostat (old models) and in most cases you don’t need an extra wall plate.

#3 LuxPro PSD010B Heat Only Thermostat

If you need a third choice, PSD010B from LuxPro is a popular non programmable heat only thermostat. This model is compatible with all heat only single stage systems. If your system has a fan, LuxPro has a variant of this same model named PSD010BF – which has additional fan control.

The display is rectangle shaped, with a back light, and it displays only the set temperature. The base model PSD010B has only 3 buttons, an On/Off button and an up/down control. The model with fan (PSD010BF) has 4 buttons, an additional button on the side to control fan operation.

If we put it simply, a 2 wire thermostat is one which has only 2 wires coming out of its backside. As you already know, there are different types of thermostats serving different types of heating/cooling systems. Some thermostats will have 4 wires coming out of its back, while some others will be having 5 wires or even 8 wires. So any thermostat with only 2 wires coming out of its back are generally named as a 2 wire thermostat.

As you may already know, thermostats are available for line voltage heating systems (like a baseboard heater) and low voltage heating systems (like a gas furnace or heat pump). They can not be used interchangeably owing to myriad technical reasons. Just like this, a ‘2 wire thermostat’ can be either a line voltage model (operating at 120 V or 240 V) or a low voltage model (operating at 24 volts).

The 2 wire thermostat for line voltage systems are technically known as single pole thermostat (and the 4 wire version is known as double pole thermostat). When it comes to low voltage systems, a 2 wire thermostat is usually known as a “heat only thermostat” and is used for systems like a gas furnace (with only heating option). A 2 wire thermostat can not be used for hvac systems with cooling option, or heating systems with multi stages or a heat pump.

2 Wire Thermostat – Wiring & Color Code

In the case of a low voltage (24 volts) 2 wire thermostat, there will be a ‘red’ and ‘white’ color wire coming into its back. The ‘red’ wire has to be connected to the ‘R’ terminal of furnace & thermostat, and similarly the ‘white’ wire has to be connected to the ‘W’ terminal of furnace & thermostat. Note: You’ll have to take all the safety precautions before you wire a thermostat. Remember there is risk of electric shock if you fail to keep the safety protocols.

Keep in Mind: If you are having a single stage heat only system (like a furnace) in your home, you can use any kind of thermostat that supports single stage systems. For example, you can use the Nest 3rd Gen smart thermostat or Honeywell RTH9585 wifi thermostat for your ‘heat only’ single stage system. In this case, you just need to connect the ‘R’ and ‘W’ terminals of the thermostats and leave all other terminals intact without making any connection.

The Nest 3rd Gen thermostat has 10 terminals, say Rh, Rc, W1,W2(aux) Y1, Y2, O/B, G, C, etc. You just need to connect ‘red’ wire from furnace to Rh and ‘white’ wire to W1. These 2 connections will set the Nest thermostat as a ‘smart 2 wire thermostat’ taking care of your home heating ‘smartly’.

In the case of a line voltage (120/240 volts) 2 wire thermostat, there will be  ‘red’ and ‘black’ wires coming out of its back (color can vary like ‘red’ and ‘white’ for some brands, some other use ‘black’ and ‘white’)

Differentiating – Line Volt vs Low Volt

Now let’s see how to differentiate a line volt and low voltage 2 wire thermostat. You’d be thinking it is a confusing task to differentiate, as both are having only two wires. Well, the key difference here is the ‘thickness’ of wires coming out of the thermostat. The low voltage (24 volts) model will be having ‘thin wires’ or ‘small wires’ coming out of its back, where as the line voltage (120/240 volts) model will be having ‘thick wires’ or ‘bigger wires’ coming out of its back.

2 Wire Thermostat Models

We now know ‘what exactly is a 2 wire thermostat’. Let’s review some of the popular 2 wire thermostat models used in US households.

Note: Almost all of the ‘2 wire thermostat’ models available in the market are ‘non programmable’ types. If you prefer a programmable variant or a model with WiFi or smart features, you can buy any model you like and wire it up for a single stage heat only system (by just connecting the two wires ‘R’ and ‘W’).

Honeywell TH1100DV1000 – 2 Wire Digital Thermostat

This model from Honeywell (TH1100DV) is the most popular 2 wire thermostat among all other models. This is basic heat only thermostat, with only 3 buttons on the device. The temperature range can be set from 40 deg F to 90 deg F. If you’re using it in garage mode, temperature range can be from 35 deg F to 90 deg F.

The buttons provided are, an up/down button for temperature range adjustments and an Off/Heat button provided on the side to turn thermostat ON/OFF. This model provides compressor protection to the heating system.

Emerson Non Programmable 2 Wire Thermostat

This model from Emerson, 1E78-140 is a great upgrade for your old mechanical thermostat (if you still have one in your home). Moreover, 1E78-140 is one of the best selling model in ‘2 wire thermostat’ category after Honeywell TH1100DV.

The reason I wrote this model would be a great upgrade to old mechanical thermostats is its design. The body is designed such a way that it covers any marks (on walls) which could occur while replacing your old mechanical thermostat. In most cases, you don’t need an additional wall plate. This model is suitable to be used for single stage furnace, single stage heat pump or milli volt systems.

LuxPro PSD010B – 2 Wire Heat Only Thermostat

PSD010B – is a popular heat only, 2 wire thermostat model from LuxPro. They also have a variant with ‘fan’ control, named PSD010BF – which has ‘fan’ control as an additional feature. Both models has a rectangle shaped backlit LCD display, which shows the set temperature value. They are compatible with all heat only single stage systems.

The base model PSD010B has 3 switches for control, an ON/OFF switch on the side and an up/down control on the front side to adjust temperature. The variant with fan option (PSD010BF) has 4 switches, an additional switch on the side to control fan.

Honeywell RTH111B1016

Lux Products Corporation is one of the oldest companies that have been manufacturing home products. Headquartered in Philly, this company was established in 1916, and is a leader in thermostat and smart home products.

A LUX thermostat embodies innovation and quality. You can choose whichever model that suits your interest and budget from the wide range of products they produce in the market.

In this article, we review one of its thermostat , the LUX ELV4. This is a line voltage thermostat and can be placed in your home to control 120/240 V heating only systems and line voltage (120/240-volt) hot water systems with motors up to 1/4 horsepower.

This mercury free thermostat does not only save you from heavy electric bills, but are also environment friendly.

It is a certified energy saver thermostat with programmable memory. Being a 5-2 day programmable thermostat, this allows you to program two set of schedule, one for the 5 week days and another one for the 2 weekends. It also comes with a vacay mode, which can be effectively used to reduce energy consumption, while you are away from your home for short trip. It is one of the few thermostats which have an adjustable temperature swing setting.  

For detailed information of its technical specifications and other features, read further. We have discussed some of them briefly below.

 

  • Design

 

LUX EL4 thermostat comes in a striking design, measures 1.8 x 9.5 x 7.5 inches and weighs about 1 pound. It has a clean, white rectangular body, with control buttons placed just below the display screen. It is an ETL certified 100% mercury free thermostat. The front panel flips down to allow you to access the programming buttons and the LUX patented speed dial. You can access the up/down button placed near to the display without removing the cover.

The digital display is quite simple and can be easily comprehended. It shows the time, set temperature and other vital information.

The only drawback is that it does not have a backlight. You will have to switch the lights on of the room, every time you want to view the display in the dark. The small display is another drawback to its design.

 

 

  • Programming Modes

 

Like all other programmable thermostats, the main aim of the LUX ELV4 model is to cut down the energy usage as much as possible.

The efficiency of the LUX ELV4 however, gets an extra point for its default heating schedule, which targets the savings to be upto 33% .

If you want to customize your schedule, there is provision for that as well. You can program the settings as a group of two. One group consists of programmed schedule for the weekdays, that are Monday, Tuesday, Wednesday, Thursday and Friday. The other group is for the two weekend days that are Saturday and Sunday.

For each group you can set 4 on/off periods for Morning, Day, Evening and Night. The temperature can be set to value anywhere between the 45 to 90 degrees. Unlike the Honeywell thermostat, where only two temperatures can be set over the 4 periods, here you can actually set four different temperatures for each period.

The programming is made easy through the on screen programming and the “swing” between temperatures and be adjusted easily. The LUX patented speed dial makes programming simple.

The extended flexibility of programming includes a vacation hold setting, and a temporary temperature override for manual adjustments.

 

The relay clicking sound while the thermostat goes off and on, is quite loud, this makes it unsuitable to be placed in the bedrooms.

 

 

  • Compatibility

 

If you want a thermostat for your heating only system with a 20 amp circuit breaker, then opt for LUX ELV4. It has a universal design suitable for both 2 pole and 4 pole wire applications.

The devices which are compatible with LUX ELV4 include: line voltage heating systems like baseboard heater, cable and ceiling heaters.

For heating applications which have an inductive load, like a hot circular pump, it can be used only for motors with horsepower up to ¼ (for 120V) and ½ HP (for 240V)

Note: This thermostat CANNOT be used for your cooling system or if your heating appliance has both resistive load such as an electric heating element and an inductive load like a blower fan.

 

  • Installation

 

The ELV4 LUX thermostat is easy to install and fits into a wall mounted junction box. It is advisable to check for the line wires and load wires before you start installing, as relying on colour codes for wires may not be suitable for an old wired home.  Always call a licensed technician to install this product, to avoid unnecessary damage due to improper installation.

 

  • The swing setting

 

The one distinguishing feature of this thermostat is its “swing” feature. It allows you to set temperature before the heater/fan will cycle. This adjustable differential swing is a great plus of this product.

.

 

  • Power Source

 

The LUX ELV 4, is hard wired to your 110vac house current and batteries are needed as a back up so that the settings remain intact even in the case of a power failure.

Each unit needs 2 AA batteries and the company recommends using the batteries of only 2 major brands. These are non-rechargeable batteries and therefore needs to be replaced every now and then.

LUX ELV4 is a certified energy saving thermostat and is a great buy if you are energy conscious. Along with all these features, it comes with a heating on/off option, which enables you to turn off the heating during summers when heating is not required.

This boosts the energy saving capacity of the thermostat.

If you consider the cost, it is quite fairly priced as compared to other company thermostat with similar features.

 

You can be assured of a reduced energy bill without compromising on your comfort.

 

Let me wrap up this review, highlighting the pros and cons of the product in a nutshell:

Stelpro KI Z Wave plus, the North America’s pioneer Z wave enabled line voltage thermostat is wired directly to the power source. This means you need not worry about changing the batteries and the additional cost involved in the process.

This thermostat works with 120V (upto 2000W) and 240V (upto 4000W) baseboard and convector heaters. It cannot be used for heating systems with fans, like a fan-forced heater. The temperature can be set in the range of 41 deg F to 86 deg F and can be toggled between its two modes namely eco and comfort mode.

This Canada made model uses the Z wave protocol and hence gives the liberty to remotely control your thermostat, through an z wave gateway controller like Samsung SmartThings, Vera, Wink etc.

If you are new to the concept of Z wave protocol, and are wondering what is so great about it, here is the answer.

What is Z wave protocol?

Z wave protocol is one of the smart home wireless standard which is now becoming an integral part of any smart home system. If you have a smart home, you must be familiar with the idea of IoT where the devices are interconnected over the internet connection and are controlled by an app on your mobile phone.

The Z wave devices follow such protocols and have an upside that you barely need to do anything. These devices find each other on their own and create a strong mesh network to work seamlessly giving you all the comfort you desire.

Stelpro KI Z wave plus uses a Z wave plus protocol which is nothing but a newer version of the Z-wave system.

This upgraded system provides additional advantages like better RF range and access to more RF channels.

This unit is ideal for the smart home lovers who love to save some good bucks on energy bills via  a smart solution.

A proper programming of this thermostat helps you to cut down your electricity bills.

Z wave plus technology aids in activating the scenes and several other activities like temperature adjustments and switch the lights on/off, activating the safety and entertainment systems etc.

This was a brief of the Stelpro KI Z Wave plus thermostat.

A detailed review is given below, read on to know more.

 

  • Design

 

The Stelpro KI Z wave plus thermostat comes in a 5×5.2×2 in rectangular package. It has a small yet clear LCD digital display, the details of which have been mentioned in the next point. Below the display leis two buttons exclusively for temperature control.

There is no provision to switch off the heater though, so you will need to set the temperature to the minimum possible temperature. It is designed to be sleek and stylish that would compliment any wall. The vertically placed buttons give ease of access to control the temperatures.

 

  • Display

 

The digital LCD display of this thermostat is easy to read and gives out the vital information in just one look.

If the temperature displays in °C then it will have a 0.5°C resolution. If you want a °F temperature display then it will have a 1°F resolution.

It also has the additional feature of displaying the outdoor temperature, provided the unit is connected to the sensors outside through the Z wave. The LCD indicates if the unit is connected over Z-Wave on its top.

It displays the ambient temperature, set temperature, Z wave connectivity and menu for advanced temperature settings. Along with these, it also indicates the mode in which the thermostat is running like frost free mode, eco mode like so. Heating status is also displayed on the LCD screen through a graph which has 4 bars. If it shows no bar, it means 0% heating, 1 bar indicates 1-25% heating. Likewise, 4 bars indicate 76-100% heating. In short you get a quick brief about the overall status of your heating system.

The back light of the display can be controlled, through the advanced menu settings. It can be set to turn off after 15 sec of inactivity or can be dimmed to 50% after 15 sec of inactivity or can be set to be on at full intensity throughout.

 

  • Advanced Settings

 

The Stelpro KI Z wave plus offers various lucrative features. Just scroll down the advanced menu on the LCD screen and you have modes to choose from that would make your home comfy and your pocket feel heavy.

You will need to press the UP/DOWN buttons simultaneously for 3 seconds to get the advanced menu. You can use the UP/DOWN button to select the 6 menu options.

To cut down the energy consumption is the foremost reason, why we opt for a smart thermostat as this. So obviously you need to be familiar with the various energy saving modes.

The thermostat basically has 2 modes with a pre set temperature namely comfort mode [pre set temperature:21°C (70°F)], and  Eco mode [pre-set temperature 17°C (63°F)]. These set temperatures can be changed and varied as long as the temperature lies in the range 41F and 86F. When the thermostat is connected to other Z wave devices, it switches automatically to eco mode or comfort mode. For example, if the motion sensors sense an empty room, then the thermostat will automatically switch to eco mode.

Another feature that gives you the flexibility of use is that you can exclude the thermostat from your Z wave network anytime you want. The Z wave menu option gives you the liberty to add or delete the thermostat from your Z wave network. You can also toggle between the two temperature format which are oC and 0F.

If you are worried about the unauthorized tampering you can always use the lock option that safeguards the thermostat from all the wandering hands. The backlight status of the screen can also be selected from 0%, 50% and 100%.

If you want to exit the advanced settings, repeat the same procedure, that is press the UP/DOWN button simultaneously for 3 sec. If the unit is kept idle for more than 30sec, it will revert back to the main home screen.

 

  • Interoperability

 

The stelpro KI Z wave plus unit has an immense ability to exchange or make use of the Z wave protocol to transfer information among the devices. This feature is termed as interoperability. This means this unit can be included in any Z wave network, even if the other devices under this mesh are from different manufactures. Together these devices will work to make your home smart. You can control these appliances through a Z wave gateway software such as Samsung smartthings, vera etc. on your phone or Tablet.

 

  • Compatibility

 

This line voltage thermostat is basically designed to be used with electric baseboard heaters up to 4000 W for 240V appliance and up to 2000W for 120 V appliance. It also works with convectors.

The devices that are NOT compatible with this unit are:

  • Inductive load
  • Central Heating System  
  • Fan-forced heater (unit containing motor and fan)
  • Heating load outside the specified ratings

 

  • Installation

 

The installation procedure has been clearly and concisely mentioned in its instruction manual. Both 2 wire and 4 wire installation are possible.

Before installation, a proper location needs to be selected that would provide the optimal results from this thermostat.

It should not be installed at locations where the ambient temperature can be changed like anywhere near to the window, for example.  

Ensure that you follow all the installation instructions carefully. It is always better to seek professional help.

 

  • Power Source

 

This unit does not require batteries. It is directly wired to directly to the power source. It uses the variable duty cycle of the heaters which contribute to its silent operation.

The line powered KING ESP programmable thermostat comes with 3 wires for installation.

For extra comfort, the temperature swings have been reduced with a 3 minute cycle rate.

These were some of the key specification of this thermostat in a nutshell. To know more about these in detail, read on.

Design

 

 

The KING ESP (120V and 240V) has been given a contemporary style design. The King ESP120 and ESP240 both look like a small rectangular box with dimensions 3.125”×1.25”×4.875”(W×D×H).  This shallow design allows more wiring room inside full electrical box. The thermostat has a large LCD display and Temperature UP/DOWN control button at the front. The program control buttons are placed inside the front cover, safely secured from wandering hands and unauthorized access.

The display backlight and the system can be controlled with their respective ON/OFF switches placed at the bottom of the product. This single pole thermostat comes with three wires; the third one is for the power supply.  The red LED indicator tells you when the heater is ON. One drawback in its design is that you will have to snap off the front cover to access the control buttons. Taking it off and placing somewhere near may lead to its unintentional loss. All in all, it has a simple yet classy look.  

Display

 

 

The digital LCD display of the 120V/240V King ESP thermostat takes up the most room on its front panel. The coloured backlight of the display changes when the temperature changes. It has blue back light at 650 F and red back light at 75oF. The display shows the vital information like the day of the week, room temperature, set temperature, time, mode selected and the programming period in action.

The illumination of the screen can be controlled with ON/OFF button at the bottom of the thermostat.

Compatibility

 

 

The maximum wattage rating for ESP120V is 2640Watts and that for ESP240V is 5280 Watts

Both the variants 120V and 240 V thermostats are suitable to be used for the line electric heaters such as baseboard, fan-forced and others. Both models are 22 amp thermostats and can be used if you have a 2 wire system at your house.

NOTE: These units cannot control cooling; they have been designed to be used with heaters only.

 

Programming

 

One of the features of this thermostat that sets it apart from other 7 day programmable models is that it has 7 individual day programmability. This means you can set a different schedule for each day. For every day, you can set 4 temperatures for the 4 periods.

The temperature set point ranges from 44°F to 95°F. It is powered with memory back-up in case of power outages.

The default set temperature will be the one which you have programmed. That means after a power outage the thermostat will retain the set program. This negates the need to reprogram after every power failure.

Temperature Swings

 

 

One of the features of a “good” thermostat is a low temperature swing. The temperature swing in this thermostat has been reduced by the delay provided between cycles. A 3 min delay has been provided that minimizes the temperature swings to give maximum comfort. This means when the program shifts from a cycle say the morning cycle(where temperature is set at 70oF) to the day cycle where the temperature set is say 680F, there will be 3 min delay.  During this delay the thermostat will shut off and will wait for the room temperature to cool down.  

Efficiency

 

 

The electronic thermistor sensor of this product takes temperature sample every 60 seconds, for a better accuracy and efficiency. The 22 amp 240V model has a test accuracy of 1.5oF . The 30 amp snap action relay works efficiently to control the heater. This reduces the energy consumption of your heaters and saves you a lot of bucks on the energy bills.

Installation

 

 

This thermostat comes with 3 wires for installation, instead of the usual 2 wires for a single pole thermostat. The third wire is connected to the display for its backlight. The installation is quite simple and fuss-free. There is no need of a neutral wire for this unit to operate. An experienced professional can take only few minutes to install this product. The installation manual guides you through the process.

 

Power Source

 

This KING ESP 120V/240V programmable thermostat is a line powered thermostat and requires 120V or 240V 50-60Hz power supply. It does not require any batteries for operation. However, there is a provision of battery back-up.

These were some of the important features of this thermostat in detail. These specifications meet the necessary energy requirements. Before concluding, let me give you a gist of the pros and cons of this unit.

Pros:

  • Large illuminated LCD Display
  • Backlight of the display can be controlled with ON/OFF switch placed at the bottom of the unit.
  • Compatible with all electric line heaters including baseboard , fan forced heaters
  • Program control buttons protected from wandering hands
  • 7 individual day programmability, 4 times a day
  • 3 minute delay between the cycles reduces the temperature swing.
  • 30 Amp Snap action relay improves the efficiency
  • Accurate electronic temperature sensors

  • Does not have a lock feature

So, these were some of the important features you need to know about the KINGS ESP 120/240V thermostats before buying them.

Remember to check with your heating system and your requirements if it supports this thermostat.

Cost wise this thermostat works efficiently to save you great bucks on your electricity bills. All you need to do is ace the programming and you are good to go!

 

Honeywell is a name familiar among most of the households in USA. They make products & solutions in different sectors like aerospace, home building solutions, environment, energy and safety. When it comes to thermostats, they have a wide variety of models catering to different needs. In fact, no other company has thermostat models in high number as Honeywell. In this article, we review Honeywell RLV4305A1000 – a line voltage thermostat model for baseboard heaters, fan-forced heaters, convectors and radiant ceiling heaters. 

RLV4305A is a 5-2 day programmable thermostat, which can operate at two different line voltage levels – 120 volts/240 volts. This model is single pole/2 wire – which means there will be only 2 wires coming out of the thermostat. A 5-2 day programmable thermostat will have two program settings, one for weekdays and the other for weekends. Besides these two week based program settings, a single day can have 4 different settings for morning, mid-day, evening and night.

A precise temperature control of  +/-0.5°F is ensured with Triac based switching technology, which also facilitates silent switching operation.At 240 volts, a max load of 3500 watts can be handled. For resistive loads max current is 14.6 amperes, and the load should draw a minimum current of 0.83 amperes.

So that was all about Honeywell RLV4305A in a quick nutshell. We shall discuss some of the key features of Honeywell RLV4305A1000E1 thermostat in this article, to give you a good ideas about this model. We will be covering features, technical spec, installation, pros & cons, and other aspects of RLV4305A thermostat. 

Check Price & View Details

Honeywell’s RLV4305A1000E1 is an improved version of its predecessor YRLV430A1005/U – 5-2 Day Programmable Thermostat. The new model (RLV4305A) has resolved some of the issues which the older model had.

Let’s dig deep into more of its features:

The Design

This rectangle shaped thermostat from Honeywell measures 4.8 x 1.2 x 5 inches (WxDxH). The white colored outer body is quite sleek and blends well in any room. It has 5 push buttons for control, a push button for selecting the mode and an up-down push button (for increasing/decreasing temperature or other parameters). A backlit screen for display is provided just above the mode button, at the rightmost part of the thermostat.

You may find the size a bit large, as this model is a  little bigger when compared to other line voltage thermostat models.

Display

This model has a digital display screen with a backlight. The display will be backlit for 12 seconds when any button is pressed.  The highlight of the display is current room temperature and day/time. Apart  from these two vital info, a quick look at the display will get you details like the working mode of the thermostat (auto or manual), the configuration (fan forced heater or baseboard heater etc), heating intensity and other details. It also indicates whether the settings are locked or not.

You can see the set point temperature whenever you want, by just pressing the Up or Down button once. The clock will be replaced by the set point value for 5 seconds.

 Unlike its earlier model, this newer version has a clear display which can be easily comprehended. The usual “small hand” symbol is replaced by a “man” to indicate that the thermostat is working in “manual mode”.

RLV4305A Compatibility

RLV4305A is a line voltage thermostat (which can operate at either 120 volts or 240 volts), suitable for baseboard heaters, convectors, fan-forced heaters, and radiant ceiling heaters. This thermostat is not compatible for low voltage systems (that operate at 24 volts) like heat pumps, central heating systems like a central furnace, or a boiler.

Honeywell RLV4305A is 2 wire/single pole, but you can also use this for a 4 wire installation.

Note: RLV4305A is not compatible with heating systems driven by a contactor or a relay (inductive loads).

At 240 volts, a max load of 3500 watts can be handled. For resistive loads max current is 14.6 amperes, and the load should draw a minimum current of 0.83 amperes. At 120 volts, max load can be 1800 watts.

Accuracy

One of the features to vouch for when buying a thermostat is its accuracy, as it decides the amount of energy it can save. This thermostat has an accuracy of +/-0.5°F and gives a satisfactory performance with regard to its energy saving capabilities. All this owes to its TRIAC switching technology.

Switching sounds

RLV4305A1000E1 performs its switching operation in 100 percent silence. It does not produce any annoying click/tick sounds and disturb your sound sleep or a peaceful environment. RLV4305A uses triac switching, which does not produce any switching sounds. You can install it anywhere, even in your bedrooms, and sleep peacefully.

Operating Modes

This 5-2 day programmable thermostat operates in four modes: Automatic, manual, away and stand-by mode.  The mode button is pressed to select the desired mode.

You can use the automatic mode to pre set temperatures for a day. Here a day is fragmented over 4 periods namely: wake, leave, return, and sleep.  However, only two temperatures can be set. This means that you will have the same temperatures set for wake and return, leave and sleep.

You can set a particular program for 5 days of the week and a separate program for the other two days (like weekends). This is of great use for professionals, who stay away from home during weekdays and stay at home during weekends. 

In the manual mode, the temperature has to be set manually each time a change is needed. The away mode is great if you are going out for a small trip and will be away for an extended period of time. This will set the temperature of your house to a particular set point which will save energy, and at the same time your home will be nice & comfortable when you return. 

The stand by mode is used to disable the heating. The thermostat will not work at any set point temperature in this mode. The frosting is avoided by maintaining the room temperature above 41 degree F.

Installation

The installation of this thermostat is quite simple. It can be connected in either 2 wire or 4 wire mode.  If you know how to handle the electric connections, you can install it yourself. However, I would recommend you to hire a professional electrician for the installation. The users manual provided by Honeywell guides you through the installation process.

Power Source

No batteries are used by this thermostat. It is infact powered by heater line. It retains the clock and temperature settings between the power outages (for 5 hours) which is a great advantage. If power fails for more than 5 hours continuously, you might need to adjust the settings.

Cost

The RLV4305A1000E1 is an energy saving line volt thermostat. You need not worry about the initial cost, because you can get the money back in the form of energy savings. Proper programming can reduce energy usage to a great extent, which has a huge impact on your electricity bills.

This 5-2 day programmable thermostat from Honeywell seems to be a good buy as it turns out to be an energy saver. With this, let me give a small list of the pros and cons of this product.

Pros:

  • Functional display, which shows all vital information
  • Accurate temperature control
  • Saves energy usage and reduces annual energy bill
  • Stylish Design and Sturdy built
  • Backlit display and easy to understand icons on the display
  • Dual voltage (120 volts or 240 volts)
  • Installation can be for either 2 wire or 4 wire homes.
  • Silent TRIAC switching

Cons:

  • Large size
  • Cannot be placed on its side, it needs to be placed horizontally always, so as to cool off the heat produced in it during its operation.
  • Not suitable for inductive loads

This was a quick overview of the product RLV4305A1000E1 from Honeywell

If you are considering an upgrade to your manual thermostat or installing a new device for your new baseboard heater, then I would suggest you opt for a programmable thermostat.

If you are flipping about the bucks it might cost, worry not, you can choose the simple basic digital programmable models similar to Honeywell’s RLV4305A1000E1.

Even if you pay for this one, it will pay you back the money over a period of time, by reducing your heating bills without compromising on your comfort.

I hope you got a good gist of what to expect of the product if you are planning to buy one.

Thank you for reading!

 

The thermostats placed in your homes are one of those essential devices which not only add comfort but also aids in saving energy. However, finding the best model that gives the best possible results within your budget may seem challenging.

This article aims at reviewing one of the programmable line voltage thermostats which fits the concerns of those who want a basic digital programmable thermostat the ones without the smart features.

In the sparse realm of the 7-day programmable line voltage thermostat that supports electric baseboard heating convector and fan-forced heaters, Aube TH106 model by Honeywell is surely one of the best buys. It looks stylish and has numerous features to program your schedule so that you can have a smile while looking at your energy bills.

Check Price & View Details

What kind of thermostat is it?

As already mentioned, it is a digital thermostat, sans the smart features. You can program the schedule for all the 7 days of the week. For each day, you can set temperature for 4 periods. It also comes with pre-programmed settings, which is aimed to give you the best economic results.

It is two wired device and supports both 120 V and 240V heating unit. Only a few programmable models have 4000watt option, it is one of them.

Let me give you a brief about its other striking attributes, to help you identify it as a good choice

  • Design

Aube TH106 is a rectangle shaped thermostat which looks stylish and blends well with the interiors of any room. It has a digital display screen on its right. It has two sections, one where the screens and control buttons are placed and which can be opened, and the other one has metal fins which act as a heat sink. This actually contributes to its large size.

Talking about its dimensions it has a height of 4.9 inches and width of 5 inch. The depth is about 1.5 inches, which means it won’t stick out of the wall much. Programming control is facilitated through the easy push buttons placed just at the left of the display. The attractive design is one of its peak advantages when compared to other models of the same category.

  • Display

The digital display of this thermostat is quite easy to read and understand. It, however, does not have a backlight, since this one comes with just 2 wires. It shows all the vital information like day and date, set-point temperature, actual temperature, operating mode and period and the live heating power used. You can monitor the power being used for heating through the power heating indicator in the display.

The display is clear and can be comprehended easily once the icons are known to you. Just a glance at it, and you will know in which mode the thermostat is working and at what temperature it has been set.

 

  • Compatibility

 

If you have a 120v or 240 V electric baseboard heater, convector or fan-forced heater, you can install this thermostat. However, since this works on a comparatively low ampere, it cannot operate relays. Also, make sure your house supply runs on 60 Hz frequency. This thermostat is also ideal for radial ceilings.   

  • Accuracy

The accuracy of this thermostat is found to be bang on! This one feature stands out from the rest, as this thermostat has been rated to have the best accuracy in the market among the models of this category. This leads to its amazing on-point temperature control of about (± 0.15-Degree Celsius and 0.27-Degree Fahrenheit). Users have complimented the thermostat a lot for its perfect temperature control.

 

  • Switching sounds

 

Aube TH106 boasts of 100 percent silent switching. Yes, it is free from the annoying clicking sounds that disturb your sound sleep or a peaceful environment. Many thermostats have the drawback of a clicking sound each time the switching happens. The TRIAC switching of this thermostat, however, is smooth and works without a sound. Therefore, it can be placed in your bedrooms, to make your sleep cozy and comfortable in a noiseless way.

 

  • Operating Modes:

 

It has basically two operating modes: Automatic and manual. If you have a proper daily schedule, then programming a schedule that fits your timings would give you the best results. This means that you will be using the automatic mode that makes the thermostat follow a pre-programmed schedule for the 7 days of the week.

Even though the makers boast of providing 4 periods per day, you can actually set only two temperatures per day. This means your room will be nice and toasty in the morning when you wake up, cool when you are away, then again heat up in the evening and then cool down again at night.

However, in the manual mode, you have to set a temperature, and the thermostat would work on that until it is changed by you.

 

 

  • Installation

 

The manual of the thermostat can be used for the installation. It comes with 2 wires, however, with a proper technician,  there is a scope for a 4 wire installation as given in its manual. In case you are not a pro electrician like me, I would definitely recommend you to hire an electrician to install this device. It cannot be installed vertically as it vents out a decent amount of heat on to its metal fins that act as a heat sink.

It comes with aluminium wires though, which may need an antioxidant grease coat on them while hooking if your household wiring is copper.

 

 

  • Power Source

 

This thermostat is powered by batteries and has battery-free back up. This means you need not worry about losing the program to the power outages. Your programmed schedule will be held securely in its memory.

  • Cost

Aube TH106 is certified to be an energy saver thermostat. This implies it would pay for itself in the long run when installed and used properly. The cost is not much, you can check the price at amazon.com.

 

These were some of the features of the 7-day programmable line voltage AUBETH106 thermostat.

To wrap it all up, let me list out the pros and cons and conclude the article.

Pros:

  • Striking Design
  • Sturdy built
  • Useful display, with all the important indicators, especially the power heater indicator
  • Installation is quite hassle-free
  • Accurate temperature control
  • Silent switching

Cons:

  • The display does not have backlighting
  • It comes with only 2 wire, which may not meet the electric code requirements at certain places.
  • Large size
  • Cannot be placed on its side, it needs to be placed horizontally always.

So, this is my review of the AUBETH106, to give a brief idea about the product. Hope you liked the write-up and it helped you in deciding whether the unit should control your heating system.

Are you planning to upgrade your non-programmable line voltage thermostat ( for baseboard heaters) to a brand new programmable model, that not only has the digital features but also is easy on the pocket?  Honeywell is one company, which not only produces reliable but also pocket friendly thermostats of all kinds. Honeywell TL8230A1003 is one of the best selling line volt thermostats (suitable for heating systems like baseboard heaters), that is digital, programmable and affordable. 

Owing the increasing energy rates charged by the companies, we tend to look for economic options. Therefore se days, its always better to opt for a programmable thermostat rather than a non-programmable one.

The digital thermostats have huge effect on reducing your monthly expenses in terms of the energy bills. Regulating the temperatures and using the thermostats only when needed, help a lot in saving energy.  

If you do not prefer the high end digital models that have wi-fi capabilities and just want a basic and simple programmable line thermostat for your electric baseboard, then choosing Honeywell’s TL8230A1003 would be great for you.

Honeywells TL8230A1003 is a line voltage 7 day programmable digital thermostat and is available on many online retail sites like Amazon.

What makes it a fairly good choice?

Before you decide to invest some of your hard-earned money on a thermostat, would it not be nice to know if it suits your desires?

To know you made the right choice you need to know what sort of model it would be like how it would look like, what modes are available etc.

This thermostat comes in with two mounting screws and four solder-less copper wires for connection. It has great easy to use display and a compact design

Let me break down more of its other aspects in points, to give you a concise and clear idea of what to expect of this thermostat.

 

  • Design

 

Talking about the design, it is 4.8 inches in height and 2.8 inches in width. The depth is not much since the front does not stick out from the wall much. It is a vertical thermostat and hence looks compact.

It has non slip rubber buttons on both sides to control and program the settings. These are however small ones, which may cause inconvenience while using them. Another drawback in its design is that these buttons do not have a backlight. Thus, you will find it difficult to change the settings in the dark.

Next the arrangement of buttons has been made in such a way that these are easy to use. However, you must be careful to not to press the “clear” button, accidentally as it is not provided in a separate area. Pressing “clear” button will erase your program, and you will have to set it all over again.

It has a conventional rectangular box design, the ones which you usually see in most of the honey wells thermostat, nothing modern or trendy like its ecobee or nest counterparts

It comes with a digital display which has been elaborately reviewed in the next point.

 

 

  • Display:

 

This thermostat has a large backlit digital display. You will love how clearly it displays the important information, like time, actual temperature and the set temperature along with the mode in which the device is working. Not only this, it also shows a bar graph which indicates how much power is being consumed by your heating/cooling system. It has a green background which makes the numbers easily visible during the night or low light times. A button at the bottom is provided for lighting the back light.

So, if you prefer a large, clear digital display which can be easily read in any lighting condition, this thermostat is right one for you.

 

  • Modes:

 

The thermostat basically has two operating modes: Automatic and manual modes. As already mentioned this one is a 7 day programmable thermostat. This comes with a pre-set schedule. So, in the automatic mode you can either use this schedule or program your own schedule.

 

It provides a completely customizable programming option, with four different periods(sleep, wake, return, away) for a day. You can easily set the program to set the temperature for a whole week, day wise. Even if you are going to be out of town, you can use the “vacay” option. This option, however is not programmable.

 

You cannot set four temperatures for a day even though a day is divided into 4 periods. You can have same temperature for “sleep” and “away” periods and same one for “wake” and “return”. This means for an entire day you can set two temperatures only.

 

In the manual mode, the thermostat would not follow a programmed schedule, rather would just work at the set temperature for the entire day unless changed by you.

 

 

  • Compatibility:

 

This aspect is the most important one to be considered while shopping for a thermostat. You need to know your heating/cooling system before setting out to buy a thermostat. Since all the thermostat do not support all the heating systems, checking compatibitly with your system is a must.

So, if you have 240V line voltage electric baseboards, convectors and fan forced heaters (resistive rated loads) then you can use this thermostat without any apprehension. It is perfectly compatible with these home electric heaters.

 

  • Switch on/off sounds

 

One of the most favourable features of this thermostat is its silent relay. You will be free from the constant ticking sound every time the thermostat changes its temperature settings in the timed modes. This provides a great relief from the annoying sounds during the switch on and off moments. It has been carefully sound proofed for silent operation which has been a common cause of concern in the conventional thermostats.

 

 

  • Installation:

 

Installation of this thermostat can be done by self, if you are familiar with the wiring stuffs. The device comes with a detailed manual that describes the process and precaution to be taken while installing it. However, if you are lay man with not much experience in handling heavy voltage, you must hire a professional to save your life as well as your home wiring. The installation is pretty simple and can be simply done by a professional electrician.

 

  • Cost

 

This is another major factor which decides your thermostat. Cost of this thermostat is fairly attractive, since I find it quite reasonable when comparing it with its nest and ecobee counterparts.

Moreover, it has an accuracy of about ±1 F. This saves up to an additional 10% on your heating bills. So, the money you invest on it will come back to you iver a period of time in the form of savings. Sounds great, right?

 

  • Power Source

 

This thermostat is battery powered but there is no need to change the batteries for a ling time. It does not have battery back up though. This means in the event of a power outage, the programmed settings will get erased and you will have to re-program the temperature settings again when the supply comes back.

 

In a nutshell:

 

These are some of the key features of the thermostat. Hope it helps you decide whether or not to go for this one.

To wrap it up, let me just list out the pros and cons of this product precisely:

Pros:

  • Large, Backlit digital display with all the pertinent information
  • Sleek, vertical rectangular design
  • 7-day programmable option
  • Availability of the manual option, to override the pre-set schedule
  • Silent operation
  • Fits in a decent budget
  • Certified energy saving thermostat, with precision of ±1 F.

Cons:

  • Small rubber control buttons
  • No separate area for the clear button
  • Only two temperature settings available
  • Vacay mode cannot be programmed
  • No batter backup, whole program gets erased in case of a power outage

Plenty of options are there for you in the market when you shop for a digital programmable thermostat. Choose the right one for your heating/cooling systems according to your convenience and budget.

 

 

 

Owing to the growing energy charges by the energy companies, we always try and look for options that save not only energy but also our pockets. Since the cooling heating system of your home uses up most of the energy,  huge electricity bills can be reduced to some extent by using thermostats to control your heating/cooling system.

Thermostats have come a long way from its basic manual operated models to the self learning models.  Here in this article we give you a brief idea about the self learning thermostats.

Self learning thermostats are the programmable smart ones, where the thermostat is smart enough to learn your routine. It then sets the temperature accordingly, without any external assistance. These smart thermostat is a must have if you are a smart home user.   

Read on to get a brief idea about the benefits of a smart self learning thermostat and also discusses some of the models available in the market.

How learning thermostat save energy?

Thermostats are the controllers of your heating/cooling system. A proper control can thus save you a lot of bucks on the energy bills. With all the advancements going on right now, newer and easy to operate models of thermostat have also been introduced in the market. One such thermostat is a self learning thermostat, which learns from your routine and sets the temperature, on-off time accordingly.

Just teach them the temperature you like and the time at which the temperature change is needed, they will automatically chart out a schedule for you.

You can control it from anywhere, all at just a click away on your phone. Thus, you can tell it turn on the heating while on your commute, to enter into a cosy home after a long tiring day at work.

This smart gadget works on machine learning algorithm, this means for the first few days you have to provide a reference data set. Therefore, for these days you will have to program your own schedule. The thermostat will use its learning algorithm to understand your preferences and then will set a schedule that possibly suits you the best.

The energy and effort both are saved in this process. You need not worry about setting a schedule every time you leave or enter the house. Also, since the heating/cooling system is used only when it is needed, it gives an optimal performance.

Other than this, there are other reasons to invest in these smart learning thermostats. Read on to know more.

Benefits of a learning thermostat

Learning thermostats are programmable types which are designed to be clever enough to learn how and when you use your cooling/heating systems.

Since these are upper-end models in terms of cost, you must know their salient benefits before buying one, to make sure you made a fair choice.  

These days, energy conservation is gaining a lot of attention. In view of this, the prime reason which makes a learning thermostat a great investment is its energy saving nature. Since the cooling/heating systems are turned on only when needed, amount of energy wasted is reduced to a great extent. This therefore makes it an eco-friendly energy saver buy.

There are however, other reasons too that make it a lucrative option to make your home smarter.

Remote control option are available in most of the smart thermostats. The thermostat is linked to your phone through internet. Thus, you can change the temperature from any part of the world as long as you have your phone with you. This adds to the convenience factor of these thermostats.

Connecting these thermostats with your smoke or CO alarms improves the safety of your home. They can send alert messages if any thing goes wrong even if you are away from home.

Most of these thermostats can be integrated with smart home applications such as Ivee, life 360, Google home, Samsung Hub etc.

They can adjust and program your schedule automatically, through their auto program feature. So, you can sit back and enjoy in your room, made cosy without any programming hassles.

They are designed to pay for themselves, as they aid in reducing the energy bills and saving decent amount of bucks for you. Hence, they save you from the huge bills that may sum up due to the unnecessary use of your heating/cooling systems.

The Best Learning Thermostat

If we talk about smart thermostats, it is interesting to know how and what gave the idea to its development. Stuart Lombard, the founder of ecobee in an attempt to reduce the energy bills purchased some already available programmable thermostats. When he releasied that these thermostats did not meet his demands, he invented a smart thermostat which was easy to use and saved considerable amount of energy.

Following the launch of smart thermostats by ecobee, many other companies followed its lead. One such company is NESt, who in the year 2011, launched the first self learning thermostat.

Many Models have been launched since then, which may confuse you to pick the right one for you.

Let us give you a short review of two of the leading thermostat models. This may help you in recognising the features to look for when buying a self learning thermostat.

NEST Learning thermostat

 

 

One of the most advanced nest learning thermostat is the nest thermostat E. Here it comes with a large display, far sight screen and wide compatibility with heating systems.

It not only learns and manages your schedule, it also provides temperature suggestions that help your thermostat to be energy efficient.  In fact you are always encouraged to stay in a leaf zone which means you are in the eco safe zone. You earn a green leaf if you stay in that zone. At the end of the month you will get an email telling you how much leaves you have earned. Sounds great, right?

Also, another interesting feature is that, if you wish to set your program manually without following the one set by the thermostat, it will form pattern based on your choices.

 

The true Radiant mode of this thermostat is another very fascinating feature. It learns the time taken by your home to reach a fixed temperature and sets the time accordingly.

The control can be done not only through nest applications, but also through google assistant, and amazon alexa.  Thus you can integrate the learning thermostat with other smart equipment in your home, and control them through a single application on your phone.

Ecobee Smart Thermostats

The Ecobee smart thermostats are not “self learning” like Nest models. But they are definitely “smart thermostats” with all those high end smart features.

I’ve added Ecobee models (Ecobee 4 and Ecobee 3 Lite) in this article as an alternative for Nest models (Nest 3rd Gen or Nest E). For any reason, if you don’t prefer Nest thermostats, Ecobee models prove to be a great choice and they are equally good as Nest by all means.

 

 

This Canadian company have grown over the years since its launch. They were the first ones to introduce the smart thermostats. However, the learning feature were incorporated much later.

ECOBEE4 is its flagship thermostat with amazing features has an in-buit Alexa.

Alexa listens and obeys your commands and sets the temperature accordingly.

Even though you can tell this thermostat to turn on and off along with that to automatically set the temperature, it does not learn your behaviours in the same way a nest learning thermostat does.

It however learns when you are away or home through its home/away option. It uses this mode to set the temperatures accordingly, to give optimum performance.

It can be integrated with many platforms such as HomeKit, SmartThings, Google Assistant, IFTTT, which makes it interconnected with other home appliances at your place.

In case of any malfunction, an alert will be send to your mobile.

It learns you are away or home through the inbuilt occupancy detectors, which detect if someone is at home or the home is vacant. It then adjusts the temperature accordingly.

So, if you are looking for a simpler version, where you only need the thermostat to learn whether there is a person at home or not, this ecobee4 option is better for you.

 

Self learning thermostats are not only eco-friendly but pocket friendly too.

Now that you have an idea of what to expect from it, go add this smart gadget to complete your smart home. Their installation process is also does not require an expertise. Once you start seeing how much you have saved on bills, the initial cost will seem worth.
