It hardly matters if you have a big family or just you and your lovely pet member – multiple inhabitants in a house always call for catering various needs. And probably as a homeowner, you are providing all the needs of your adorable pet. But do you pay attention to your home’s thermostat setting while leaving behind your pets alone at home?
It’s true that pet animals like dogs, cats or rabbits can survive at the temperature ranges from 30 F – 115 F. (Read more about Thermoregulation in animals) But the pet animals usually grow up in pleasant ambient temperature. Moreover, they don’t feel similar in the same temperature as you feel. Hence, extra care should be taken while setting the temperature of your home’s HVAC system for your pets well being.
How does room temperature variation affect a pet animal?
Pets have their own biological temperature control capability. Hence, they easily adapt to the temperature they usually grow up in. This means they are comfortable with the same temperature as their homeowners.
However, like a human body, a pet’s body is also prone to disease and uncomfortable feeling for abrupt temperature changes. The reason behind it is, though a pet’s body can regulate its body temperature to the comfort level of the home temperature, it can’t control the impact of sudden temperature change on its body.
So, the rule of thumb is while lowering or increasing the temperature of the thermostat it should be set comfortable for you, and so for your pet! And switching off the thermostat either in summer or winter is not at all a good idea. This will leave a pet in a miserable condition with either extremely hot or cold temperature.
Few physical traits of a pet which must be considered:
It’s not only your perception or “own feeling” that should be based to adjust your home’s thermostat setting. There are many other factors which should be considered because not all dogs or cats belong to the same league. The first factor is to identify how acclimated they are to temperature changes.
#1 – Origin and Climate zone: A dog that lives outside most of the time in a hot and humid climate can tolerate higher temperature and humidity. On the other hand, a dog that is shifted from a colder zone to a hot climatic condition like 90F needs a warm surrounding.
#2 – Age:- is a prime factor for pet animals which affects their senses and body temperature regulation capabilities. With age, animals cannot cope well with abrupt temperature changes. Cold atmosphere could cause joint pains, numbness or other health issues. On the other hand, hot surroundings leave them with risk of dehydration.
Again, kittens or puppies need higher temperatures than adult ones. Because it takes time to develop their body temperature controlling system after birth. Hence, they prefer to keep their body warmer. Otherwise, they can suffer hypothermia even in normal room temperatures as they posses lack of capacity to retain body heat.
#3 – Breeds: The physical & genetic traits (breed characteristics) plays a vital role in temperature balance & regulation. For example, a dog with double coats (a coat works as an insulation layer for animals) feels warmer than a slick coated dog. Similarly, a Siberian cat with long hair feels warmer than a cat with less hair.
#4 – Size: The size of the pet animal also decides their heat retention capacity. For example, a smaller cat or dog with slim structure normally carries less fat. Hence, they need more heat to keep their body warmer. On the other hand, a fatty dog or cat retains more heat due to their body fat.
#5 – Health: Your pet may undergo different health conditions. If your darling has a thyroid problem, it cannot tolerate too much heat. Similarly, if the animal is suffering an infection or other types of sickness, they need a warmer environment.
Further, if the pet is diagnosed with hormonal imbalances, or any organ conditions of heart/kidney, or a medical condition like diabetes, they could not maintain regular body temperature themselves in such conditions and are prone to get sick with changes in weather.
What is the best temperature for pets in summer and winter?
Of course, it depends on the type of pet animal that belongs to your home. Here we will discuss from the perspective of dog and cat.
Best temperature settings for dogs:
Dog’s normal body temperature runs a little higher (3-4 degrees) than humans. However, their comfort levels are same as humans. Hence we advise not to leave them at freezing temperature (32F) or too hot temperature (105 F). The recommended thermostat setting during summer is from 78 degrees F and 69 degrees F in the winter.
However, as mentioned above several factors play significant roles in their sensitivities. Hence, a pet’s discomfort level should carefully be monitored before setting the thermostat temperature level.
Best temperature settings for cats:
Usually, cats can tolerate quite high temperatures than humans as they evolved in the desert. Cats can easily tolerate up to 126 F, and without any discomfort up to 133 F. However, it is ideal to maintain thermostat setting between 86 F and 96 F during summer.
During winter keep the temperature between 78 F and 80 F. However, if the cat is less tolerant to heat then maintain the temperature between 60F-68F.
Maintaining a consistent temperature helps a lot:
As we mentioned above, sudden temperature change affects pets adversely especially dogs. Though they have their own sweat management capability or panting ability, they cannot cope up well with extreme conditions. Moreover, this leaves them in an uncomfortable situation sometimes making them furious or away from normal behavior.
Hence, though this may sound against energy saving, it is a good practice (considering pets well being) to maintain a consistent temperature at home (a setting that you and your pets are already used to in Summer and Winter conditions)
To conclude, always consider the factors mentioned here before setting the thermostat in any weather condition. From energy-saving invest in a programmable thermostat to get rid of an extra headache while maintaining a healthy and comfortable living for both of you and your pet.
And last but not the least during your pet’s veterinarian check-up make sure your thermostat setting is working well for them, or whether it is causing any potential health issues for them. Research and invest in your thermostat and its setting to ensure a healthy life for your loving pet!
One of the common appliances found in US homes is the air-conditioner. They provide cooling during the hot summers. However, during winters when you need warm and cosy indoors, heaters are installed. This means, you need two different appliances for heating and cooling purpose. There is an alternative to all of these, the heat pump. Its versatile nature can be used for cooling, heating and dehumidifying. The working principle of a heat pump is same as that of the refrigerator. In simple words, it makes the cool place cooler and hot place hotter, by pumping out the heat from the colder area to hotter area. Therefore, during winters when it is cold outside and warm inside, it pumps out the heat from cool outdoors to warm indoors, making your place cosy and warm. Similarly, during summers, when it is warm outside and cold inside, it will pump out the heat from cool indoors to warm outdoors making your place nice and cooler.
These heat pumps use air, water or ground as a medium to pump out the heat. According to this they are classified as air source, water source and geothermal heat pumps. Out of these, most common is the air source heat pump.
Compared to electric baseboardand furnaces, these heat pumps offer better efficiency in terms of electricity use, as they don’t use resistance heating. Also, with new advancements, high efficiency heat pumps are available that provide better dehumidifying feature than the air conditioners.
The use of thermostat with a heat pump is always recommended as it adds to its efficiency. The thermostats used for furnaces and electric heaters are completely different than those used for heat pumps. This is so because, heat pumps not only provide heating but also can be used as air conditioners and dehumidifiers.
Since thermostats add efficiency to your heat pumps and also offer a lower energy usage, choosing the right thermostat for your heat pump is always important.
Here in this article, we will help you to choose the right thermostat for your heat pump.
Let’s first look at what are some of the criteria you should have in mind while selecting a thermostat.
How to choose the right thermostat for your HEAT PUMP?
As already mentioned heat pump thermostats are a bit different from the baseboard and furnace thermostats. The difference lies in their operation. While the baseboard/furnace thermostat have to control the temperature of a heating device, the heat pump thermostats switch from heating mode to cooling mode according to the seasonal variations. This should be kept in mind while choosing a thermostat for your heat pump. Typically, all thermostats come with clear labels as to what devices they are compatible with. Look for thermostats compatible with a heat pump.
Also, there are heat pumps with auxiliary or emergency heat, like a multi level furnace. Check your heat pump if it has that feature or not. Choose thermostat accordingly, that is select a thermostat that is compatible with your kind of heat pump.
Next is choosing the models for thermostat. This completely depends on your range of budget. You have programmable and non programmable thermostats as well as manual and digital thermostats available in the market. The programmable ones are more efficient and provide cool features like auto turn off/on, wi-fi support etc. while the manual thermostats are old school ones, simple, easy to use, pocket friendly yet not as efficient as their digital counterparts.

2018 has already become a stellar year for technologies, and the star of them all? Home-based IoT or Internet of Things! The electronics have evolved far beyond their “manual input” titles. They have become smart. Now, they can learn from humans and do things that will help us live better without us even having to tinker them all day long. One such invention is the Smartphone controlled thermostat or smart thermostats as they are widely known.
Apps are made available in Google Play Store and Apple iTunes by respective companies that users can download to control their smart thermostats.
Now, this technology is something revolutionary. Imagine a system adjusting the room temperatures based on your activity or presence! Imagine the heater or air conditioner in your home working on idle when you are not home but springing back to action a few moments before you reach back home! Thanks to the smart thermostat, you will no longer have to imagine it! The technology is already here.
If the Smart thermostat doesn’t win you over with its smart features, the energy savings definitely will!
What are Smart Thermostats?
Smart thermostats mainly fall into two categories:
Smart thermostats that learn from their surroundings
Smart thermostats that interact with the internet to enable programming
Now, the best thermostats are a hybrid of the above-listed points. Hence, the top of the line smart thermostats can learn on their own while being connected to other devices.
What Do You Stand to Gain by Using a Smart Thermostat?
The predominant reason why smart thermostats have gained so much traction can be attributed to their role in cutting costs when it comes to electricity. If your home air-conditioners were to make changes to the temperature inside your home based on the outside climate and the level of activity, then you are looking at a system that will give you optimum performance.
Also, the air conditioning and heating systems of your home can be centrally controlled from your smartphone. There are many advantages just through this option such as:
You can control the room temperature at your home when you are at work.
You can keep the home at a stable temperature when you are away on vacation.
The smartphone will alert you if there are unusual temperature changes in your home.
The Geo-Fencing technology enables the thermostat to adjust the temperature as you are on your way back home.
It can track you through the home to provide cooling in the room that you are currently in.
You can view the energy usage reports through your smartphone.
The EPA has estimated that a home enabled with smart thermostats cuts down on electricity costs by a factor of 20 to 30 percent.

With the onset of smart assistants and AI, there hasn’t been a better time than now to revolutionize how you live!
If you are living in the US, then a proper home heating system is a must during those chilly winters. Most of the American households depend on furnaces for the same. Furnaces are used mostly for central heating system. These systems work by blowing heated air through ducts that use grills or air registers to deliver warm air, throughout the house. This duct warm air heat distribution system is powered mostly by electricity, natural gas or fuel oil. In terms of AFUE(annual fuel utilization efficiency), the furnace powered by electricity has a higher efficiency in the range of 95% to 100%, since it is free of flue loss through a chimney unlike the ones powered by gas or fuel oil. However, with growing electric prices across different parts of the country, the choice of an electric furnace seems uneconomical.
Nonetheless, the energy consumed by these furnaces can be controlled by controlling their temperature setting, using a proper thermostat. Thermostats are nothing but temperature sensitive devices that maintain the temperature at a set point. You have numerous options to choose from a variety of thermostats, which may leave you confused.
Here are some points that you can consider while choosing the right thermostat for your furnace.
How to choose the right thermostat for your furnace?
1. Know your heating system
The first and foremost thing you must do is to check what kind of heating system you are using at your home. Basically heating furnaces are of two types: one, which is common is the single stage heating system and the other one is multi stage heating system. How to know which one you have at your home? If you have single stage heating it means you have a furnace that has only one level of output. A multi stage heating system has a primary heating system like a furnace and a secondary heating system like a solar panel which acts as an emergency heat setting system.
2. Study about the various thermostats available in market.
Now days, the market is flooded with variety of thermostats. Knowing your heating system helps in deciding which kind of thermostat will suit you the best. Thermostats now come with clear labels suggesting with which system they work best. Some of the commonly found labels include:
Works with Single stage heat or cool: This label indicates that the thermostat can be used if you have a single stage heating and cooling system.
Works with 2 Stage or multi-stage heat or cool:This means that the thermostat can be used if you have a multi-stage heating or cooling system.
Works with 24mV:This thermostat is mostly used for fire-place or wall furnace
Zoned HVAC: If your Heating and/or cooling is individually controlled in different areas by the same HVAC system, then the thermostat with this label is to be used.
3. Choose the best model that fits your needs.
From manual to programmable, there are variety of thermostats in different shapes and sizes available in the market. Manual thermostats work with mercury relay switch and are the most economical one. The programmable thermostats on the other hand, is quite heavy on the pocket as it offers many functions and claims to have the best efficiency in cutting down the energy usage.
Here in this article, we have picked up a few thermostat models and reviewed them. This will guide you in choosing the best thermostat for your furnace.

Looking for something that would cut down your energy bills? An investment in thermostats would be a wise idea. Now if you still wonder what kind of a device this is, a thermostat basically controls the temperature of a system (this could be your air conditioner, baseboard heater, heat pump, room heater etc). This device not only helps in cutting down your energy bills, it also ensures proper cooling/heating of your home appliances. However, there are different types of thermostats to serve unique functions. You have to buy the right thermostat that serves your purpose. A little research before buying would help you choose the right thermostat model and save you a lot of extra expenses. In this article, we review line voltage thermostat models (aka line volt thermostat) which are thermostats that uses direct line voltage to function (say 110 volts). Line volt thermostats are usually used to control heating equipment like baseboard heater, room heater etc.
When we speak of thermostats, they are basically of two types, namely line voltage thermostat and low voltage thermostat.
This article helps you make better choices while you shop for line voltage thermostats.First and foremost thing you should know before you buy any device is its basic function.So what is actually a line voltage thermostat and what is its area of application?
What is Line Voltage Thermostat?
Line voltage thermostat is a type of thermostat that uses the direct line voltage(USA: 110V). This type of thermostat is used in households that have baseboard heater or electric heater. A line volt thermostat usually has thick wires ( two or four wires) coming out of its back. They are mostly installed in series with the heaters at line voltage and switch on and off the mains power to the heaters, according to temperature settings. The shortcoming for this type of thermostat is that, the thermostat may reach the set room temperature even before the heater brings the room to the set temperature, thus shutting of the heater early than desired.
The figure below shows a typical line voltage thermostat, with its wires coming out of its back.
Backside:Line Voltage Thermostat (4 Wire/Double Pole)
Now, you might have a basic idea of what a line voltage thermostat is, but still got second thoughts to go for the line voltage thermostat or low voltage thermostat – right?.
Let us clear that for you, follow the bullet point nutshell explaining difference between the two.
Note:- In any case, please note that a low voltage thermostat is not suitable for appliances like base board heater, electric room heater, heat pump, radiant heater etc. You should buy a line voltage thermostat for these appliances mentioned. Keep that noted.
Differences: Line voltage and Low voltage thermostat
Line voltage thermostat uses direct line voltage, whereas low voltage thermostat works at a lower voltage than the line voltage.
Line voltage thermostat is used mostly for electric heaters or baseboard heaters, whereas low voltage can be used for central heating systems including furnaces, air conditioning, split heaters and boilers.
Line voltage thermostat have thick wires whereas low voltage thermostat has multiple thin wires, as they mostly work at a voltage in the range 24V -50V.
The low voltage thermostats are more efficient in controlling the current than the line voltage thermostat.
Coming back to the line voltage thermostats, let us have a look the different models available in the market.

If you are looking for a manually programmed touch screen thermostat then the Lux 7 day Programmable thermostat is a good option. It is reasonably priced and gives easy usability. If you are looking for a more features rich thermostat device then there are several other options available albeit at a higher price.
Honeywell has also come up with it’s a seven-day touch screen Programmable thermostat device, just like other small size devices in the market it can do it’s part in a basic and efficient manner. The look is very simplistic in nature and all the key functions are mapped out in the main menu. The display has a neon green color and the menu titles are quite small. The price still is above the $100 mark, this may be due to the Honeywell brand name which promises a more durable and long-lasting device, but is it really enough when compared to the competition, let us take a closer look-
• It has a large touchscreen display with a back light.
• It has Smart Response Technology which calculates the amount of time it takes to reach the desired temperature and accordingly make settings for the future
• The 7 Day program can withstand power outages
• The device can be programmed for each day of the week which can be divided into 4 periods.
• The device is easy to program with words being used rather than symbols.
The device is quite easy to install and is compatible with the most heating and cooling systems. The company also gives out a one year warranty on the product. They take the Honeywell name into account when putting a price on this device. There are some alerts in the system like the filter change alert which tells you when is the time to change the filter so that the fans are working at their optimum level. The back light display is easy to read even when there is no light in the surrounding or even if the area is very well lit. The device automatically adjusts for daylight saving.
Even though we found the device slightly on the expensive side it does give a robust performance. The design is easy to use and very clear in the interface. If you are looking for a device which gives 7-day programming then you will be quite satisfied with the Honeywell 7-day Programmable touch screen thermostat.
Compared with the sister device the RTH8500D, the Honeywell RTH7600 D touchscreen thermostat is a further simplification which gives a basic functionality expected from a touch screen thermostat. Saying so, it is slightly less expensive than its higher functioning model.

Well, all of us know that a thermostat is a device that controls a heating and cooling system. The device is significant in ensuring that the heating and cooling system installed in your house works properly. Besides, this useful gadget can be set to turn heat on or off as well as to what temperature the heat will rise or fall. If you use the thermostat appropriately and responsibly, you can save enormously on your energy bills .
One important criterion to look for when you purchase a thermostat is the ENERGY STAR symbol.
Coming to the types of thermostats, they are categorized into two basic types:
1. Line-voltage thermostats
2. Low-voltage thermostats
1. Line voltage thermostats are used in single heating systems like baseboards and radiant systems. These thermostats are installed in series with heaters, probably at 240V. In this particular type of connection, the electric current flows through the thermostat and the heater. Unluckily, the thermostat itself reaches the set room temperature resulting in shutting off even before the heater brings the room to the set temperature.
2. Low voltage thermostats are perhaps more efficient in controlling the flow of electric current. These kinds of thermostats are largely used in central heating systems that use oil, gas and electricity. Besides, they are used in water heating systems especially in zone valves as well as in electric unitary systems. A low voltage thermostat not only helps you to precisely control current but also enables you to easily use the programmable controls mainly due to the fact that these thermostats operate at 24V to 50V.
A low voltage programmable thermostat helps you to have the temperature in your house adjusted automatically according to preset times. This will help you conserve energy as you can allow the device to minimize the temperature when you are away from home and maximize the temperature when you are around.
These thermostats are available in several models. Simpler ones enable you to program different daytime and nighttime temperature settings whereas the complicated ones can be programmed so that they adjust temperature in different ways for the various days and times of the week.

Well, what are the benefits of programmable thermostats?
Whenever there in an increase in temperature variation, loss due to heating and cooling from a building becomes greater. However, a programmable thermostat helps in reducing these losses by reducing the temperature variation. For instance, in the cooling season, a programmable thermostat may be set in such a way that the temperature rises during the workday when no one is at home and set to turn on the air conditioner just before the arrival of the residents; this makes the house to be cool when the residents arrive at home while still having saved a considerable amount of air conditioning energy during the peak outdoor temperatures. In addition, the reduced cooling needed during the day minimizes the demands placed upon the electrical supply grid.
On the other hand, during the heating season, this thermostat may be set in such a way that the temperature in the house drops when no one is at home during the day as well as during the night when all of them have gone to bed; it should also be set to re-heat the house prior to the time the residents arrive home in the evening or wake up in the morning. As a majority of people sleep comfortably when a room is cooler and the difference in temperature between the outdoors and indoors is greatest on a cold winter night, this significantly reduces energy losses.
These are a type of line voltage thermostats that are pretty easy to install. These thermostats operate by being triggered by metal bars that heat up or cool down. In fact, these are the easiest and the cheapest thermostats available. They have either vapor-filled bellows or bi-metallic strips that respond to differences in temperature. However, mechanical thermostats are thought of as unreliable, especially the cheapest models that use bi-metallic strips.
The major drawback you will experience with mechanical thermostats is the slow response of the bi-metallic strips that may cause significant temperature variations, above or below the desired set points. Moreover, these thermostats can be set only to one specific temperature.
Pros and cons of mechanical thermostats discussed
These thermostats are generally referred to as old fashioned thermostats mainly because they are not programmable and they are not very efficient in regulating a room temperature like a digital thermostat. Besides being the oldest type of thermostat, many people still use it merely because these are quite simple to install and use and above all, very cheap. You can see this type of thermostat particularly in older houses.
Mechanical thermostats are provided with coiled metal that expands or contracts according to the temperature. Well, this is certainly not the best way to control temperature even though it has been sufficient for most of the people over the years. Still, these thermostats result in incorrect temperature readings and it has been noted that they keep the temperatures higher than the set point. With everyone concerned about energy savings, it is important to remember that whenever your room temperature goes up by 1 degree Celsius, you end up using up to 10% more energy! Therefore, this thermostat is not a choice for those cautious energy savers.
Yet another disadvantage of using this mechanical thermostat is the slower response time that results in wider temperature fluctuations as the day passes.
This non programmable digital thermostat offers all the essential features with good performance and energy savings. Very large backlit screen is one of its biggest specialties. It also displays the room temperature and set temperature .Application: up to 1 heat/1 cool conventional systems and heat pumps with no auxiliary heat.
Dimensions: 3-7/16 ” (Height) x 4-1/2 ” (Width) x 1-5/16 ” (Depth) horizontal mounting.
Some of the details and specs of Focuspro 5000 Non Programmable thermostat are,
Most electronic thermostats fall under the low voltage category; however, you can have them for line-voltage purposes as well. These devices contain a sensor that can detect when the temperature moves above or below the desired room temperature. Many of these thermostats are programmable as well.
Dissimilar to their mechanical counterparts, electronic thermostats use electronic gadgets to detect temperatures and consequently initiate control over your heating or cooling systems. They exhibit much quicker response time to temperature variations. In addition, these devices offer you a lot of convenient features like automatic setback and programmability. Therefore, electronic thermostats are more expensive than the mechanical ones. Low voltage electronic thermostats can keep a room at the particular temperature as desired.
Types of electronic thermostats
There are varied types of electronic thermostats available on the market. There are simple electronic thermostats that do not have any programming capabilities. On the other hand, there are programmable electronic thermostats that are loaded with features for controlling the heating or cooling systems of your home in a much more efficient manner.
Non programmable electronic thermostats function similar to the mechanical thermostats; the major difference is the metal coil in the mechanical thermostat is replaced by an electric temperature sensor in this device. A tiny microprocessor that is set inside this thermostat sends ‘start’ or ‘stop’ commands to the heating or cooling system based on the reading it takes and the chosen temperature setting. In fact they are more accurate than the mechanical alternatives, but, you have to set the favorite temperature manually and make necessary changes during the course of the day manually.
It is quite obvious that you buy a thermostat to reduce your energy bills greatly. And, most of you might be interested to see how this device works, especially in these days of escalating energy prices. Well, the working of a thermostat is amazingly straight forward and constitutes some cool technology.
The traditional mechanical thermostats and the modern digital thermostats are the two main types of thermostats available. To know the working of a thermostat, it is a good idea to look at the parts of a non-digital thermostat that is still found in most of the older homes.
1. How a thermostat works – Parts of a non-digital thermostat
Mercury Switch – The mercury switch is the integral part of a thermostat which is in the form of a glass vial with a little amount of real mercury in it. The glass vial has three wires – one wire extends to the bottom of the vial, being in contact with the mercury; another wire ends on the left side of the vial so that the mercury contacts it when the vial tilts to the left; the third wire has its ending on the right side of the vial so that the mercury can make contact between this wire and the first bottom wire when the vial tilts to the right.
Thermometers – This kind of non-digital thermostat has two thermometers. One displays the temperature and is in the cover; the other controls the heating and cooling systems and is in the top layer of the thermostat. Coiled bimetallic strips are used as thermometers.
Well, what are bimetallic strips? A bimetallic strip is a bit of metal that is made by laminating two varied types of metals together. When heated or cooled, these metals making up the strip expand and contract accordingly. When this coiled strip is heated, the metal inside expands more and the strip unwinds. A temperature-adjustment lever being connected to the center of the coil and the mercury switch being mounted at the end of the coil, when the coil winds or unwinds, it instructs or tips the mercury switch one way or the other.
On the other hand, non-digital thermostats have two switches. Small metal balls are moved by these switches and these balls tend to make contact between different traces on the circuit card embedded within the thermostat. One switch controls the mode, that is, heating or cooling and the other switch has control over the circulation fan.
Now, let’s see how these parts work collectively to make the thermostat work.
2. How a thermostat works: Inner workings
When the lever on the thermostat is moved so as to turn up the heat, the lever rotates the thermometer coil and the mercury switch, eventually tipping them to the left.
When the switch tips to the left, electric current flows through mercury in the mercury switch; this current energizes a relay that initiates the heater and the circulation fan in your house. The room gradually heats up and the thermometer coil, slowly and steadily, unwinds until it tips the mercury switch back to the right, thus breaking the circuit to turn off the heat. As the switch tips to the right, a relay initiates the air conditioner. The room cools and gradually the thermometer coil winds up until it tips the mercury switch back to the left.
Fine, it is as simple as that, right? In fact, thermostats have another cool device, a heat anticipator. Before the air inside the thermostat reaches the set temperature, this device shuts off the heater. At times, parts of a house will reach the set temperature even before the part of the house where the thermostat is placed does. In such cases, the anticipator shuts off the heater a little earlier in order to give the heat time to reach the thermostat.
In addition, there is a kind of resistor in the form of a loop of wire above the gadget. When the heater is running, the electric current that controls the heater travels from the mercury switch to the resistive loop through the yellow wire. Until it gets to the wiper, the current travels around the loop; from there, it travels via the hub of the anticipator ring and then down the circuit board that is present on the bottom layer of the thermostat. Similar to any other resistor, this also produces heat when electric current passes through it. The farther around the loop the wiper is positioned, the more amount of heat is produced by the resistor. This heat is sufficient to warm up the thermometer coil, making it to unwind and tip the mercury switch to the right side; consequently, the heater shuts off.
Next, let us have a look at the electrical circuits in the device.
3. How a thermostat works: Electrical Circuits
The non-digital thermostat is built for a system that has five wires and the wire terminations are labeled as:
RH – wire coming from the 24VAC transformer on the heating system
RC – wire coming from the 24VAC transformer on the air conditioning system
W – wire coming from the relay that turns on the heating system
Y – wire coming from the relay that turns on the cooling system
G – wire coming from the relay that turns on the fan
The power the thermostat uses to switch on the different relays comes from the two transformers. The power to switch on the heating system, cooling system and the fan comes from the relays.
How power flows through thermostat when the air conditioner runs
Power from the air-conditioning transformer comes into the RC terminal. A mode switch controls a ball and this ball jumps the current onto a trace that leads to the terminal present in the lower right corner of the circuit board. A screw connects this terminal to the top layer of the thermostat. It connects to the pink wire that leads to the bottom wire of the mercury switch. If the air conditioning is on, the switch gets tilted to the right and the current travels into the blue wire through the mercury. A screw connects the blue wire to a lug in the lower left corner of the circuit card. From this position, the current moves to the other branch of the mode switch through a trace on the circuit card. The ball in the mode switch jumps this current onto a trace which is connected to the terminal labeled G that energizes the fan and the terminal labeled Y that energizes the air conditioner.
This is how current flows through the thermostat when the air conditioner is running. The same applies when the heater is running, just that power flows through the terminals labeled RH and W energizing the heater.
4. How a thermostat works: Digital Thermostats
Well, these thermostats use a very simple device called a thermistor in order to measure temperature. This is a kind of resistor allowing electrical resistance changes with temperature. In a digital thermostat, the microcontroller measures the resistance and converts that number to a precise temperature reading.
Needless to say, a digital thermostat can perform a few things that cannot be done by a regular mechanical thermostat. The most useful feature of this thermostat is the programmable settings; it is unquestionably a great money and energy saving feature as you can merely turn down the heat when there is no need for it.
5. How a thermostat works: System Zoning
Now, what is system zoning?
Have you ever noticed that some rooms in your house are always colder or warmer than the others? In fact, there are many explanations for this. One reason, as heat rises, the rooms on the second or third floors become too warm and the basement rooms are generally colder. Besides, rooms that have vaulted ceilings have a tough time retaining heat whereas rooms that get long hours of sunlight don’t cool down easily. These are merely a few reasons; however, regardless of why temperature in a room is uncomfortable, there is only one definite way to even out temperature in your house. And, that is by system zoning.
System zoning is a simple process. It involves a number of thermostats being wired to a control panel that operates the dampers provided within the duct work of your forced-air system. According to the settings of the thermostat, these thermostats continually read the temperature to their particular zone, then open or close the dampers present within the duct work. System zoning is helpful for houses that have inconsistent room temperatures as well as for heating or cooling individual bedrooms depending on the favorite temperature setting. In case you have a guest room that is normally not used by anyone, you can just shut the room’s door and close the damper. It is as simple as that.
Obviously, system zoning can help save a lot of money on your energy bills. It is believed that you can save up to 30% on a typical heating and cooling bill! As seldom-used rooms like guest rooms don’t require constant heating or cooling, the process of system zoning helps you save money by running temperature-controlled air to these rooms only when need arises.
As you know, a thermostat is a temperature-sensitive switch that turns on and off the heating and cooling systems in your home when the temperature attains a preset limit. When it comes to buying a thermostat, consumers are offered with a wide range of choice from simple manual units to state of the art programmable units that are highly efficient. Good news for buyers is that choosing a suitable thermostat for your home has become simple due to easy-to-understand product packaging and universal compatibility.
How to choose a thermostat(which thermostat do i need)?
You can use these three simple steps to select a thermostat for your home:
Determine what heating and cooling system you have at home
Choose the thermostat type
Select the features and options that best cater to your lifestyle
Now, let us see each of these steps in detail.
Step 1: Determine what heating and cooling system you have at home
Single stage – Single stage heating simply means that your furnace has just one level of heat output. You might either have gas, forced air heater or an electric AC system with a separate heating system. Well, this is the commonly found system in most places. In case you already have a thermostat, there will normally be maximum six wires coming from your wall.
Multi stage – Multi stage heating means that there are two levels of heat in your house. You might perhaps have a furnace as well as another method of heat such as a solar panel. The second level of heat source is commonly considered as an emergency heat setting. So, as the low setting is sufficient to meet the household heating or cooling demands most of the time, the multi-state unit runs for prolonged periods and offers more even heat distribution.
Heat pump – This is a single system which does both heating and cooling of your home. Normally, when a heat pump is used, you don’t have a separate air conditioning system as the heat pump is capable of performing both the operations. A heat pump is employed as the emergency heat for multi stage units since it can produce heat much faster compared to any other unit and heat up your house quickly even on very cold days.
Multi stage heat pump – This system makes use of more than one system similar to the multi stage; however, it uses heat pump for emergency heating or cooling. You will have a main heating or cooling unit and you will depend on the heat pump to enable your main system to heat or cool faster and perhaps more efficiently.
Line voltage – A line voltage system uses direct electric current instead of just 24 volts used by the typical thermostat of the present day’s modern homes. This kind of thermostat can be largely seen in older homes that still use direct voltage. You can notice that the power wires are thicker and they usually run either 120 or 240 volts on direct current. These thermostats are common in older construction particularly with baseboard heaters and electric heaters. Well, these are not used with gas heaters which are generally single stage systems. Most of the line voltage systems are mechanical thermostats. Based on the voltage of the thermostat and the house, the device will use either two or four black and red wires.
Well, have you figured out the kind of heating and cooling system in your home? Your next task is to choose the type of thermostat.
Step 2: Choose the thermostat type
These modern thermostats provide the benefit of being programmable. The best part is that you need not actually program them! These gadgets learn as you use them and can create a schedule according to your personal preferences. They can turn down automatically when you are away from home, offer you guidance on energy-efficient settings as well as provide you with monthly energy reports. In addition, these devices connect to your home Wi-Fi network; therefore, it can be monitored, set and managed remotely from a computer, tablet or Smartphone.
Remote energy management thermostat
This thermostat enables you to set, program, monitor, and control your heating and cooling system from a tablet, Smartphone, and computer. You can connect this thermostat to your home broadband network via a hub; this allows you to access the gadget over Wi-Fi from anywhere.
If you want to save energy and reduce your energy bills, a programmable thermostat is the ideal choice. It automatically adjusts the set temperature throughout thus making the most efficient use of your system.
