This article is a detailed guide to auto changeover thermostats.

Are you annoyed with your HVAC system when the temperature in your house is not automatically adjusted when the outside temperature fluctuates from cool in the morning to quite warm in the afternoon?  Do you have to manually change the settings on your thermostat a few times a day when there are temperature fluctuations in the outside temperature? 

There is a solution available – install an auto changeover thermostat!

An auto changeover thermostat will automatically change the HVAC system from “cool” to “heat” and vice versa to keep the temperature in your house always comfortable whatever the fluctuation in the outside temperatures. 

In this article, we’ll tell you what an auto changeover thermostat is and how it differs from a “normal” manual thermostat. We’ll also look at some of the benefits of having one, and what are aspects to keep in mind when you install your auto changeover thermostat.

What is an auto changeover thermostat?

The “changeover” refers to a thermostat’s ability to automatically “change over” from heat mode to cool mode and vice versa when the air temperature in the house crosses a temperature. 

After your auto changeover thermostat has been installed, you set a range for the temperature in the home. When the temperature goes above the pre-set level, the AC kicks on, and when the temperature falls below another pre-set level, the furnace/heater kicks in. 

When, for instance, temperatures are changing during the day from rather cold to quite warm, an auto changeover thermostat will automatically activate the heating function in the morning and later in the day the cooling function.

How does an auto changeover thermostat differ from other thermostats?

If you don’t have an auto changeover thermostat, your thermostat will only have a “heat/cool” setting option. You have to manually change the thermostat from “heat” to “cool” when needed.

 Unfortunately, changeover thermostats are more expensive than “normal” thermostats. Therefore most homeowners have only the manual option and need to evaluate the heat/cool situation in their houses and then manually switch the thermostat to the appropriate setting. 

If there are great temperature fluctuations during the day you can find yourself changing this setting several times a day. With an auto changeover thermostat, all the setting changes are done without human intervention.

Benefits of having an auto changeover thermostat

If you have installed a changeover thermostat with your heating and cooling system, you will amongst other things, be able to enjoy the following:

Always a comfortable temperature

With an activated auto changeover thermostat your home will always be kept at a comfortable temperature even when outside temperatures fluctuate a lot. The thermostat will automatically ensure that just enough heat or cold air is provided to keep the temperature in the house comfortable when the pre-set temperature thresholds have been crossed.  

Sophisticated thermostats learn your heat/cool preferences

There are very sophisticated auto changeover thermostats available that offer you the ultimate comfort. They have, for instance, the intuitive ability to learn your heat/cool preferences. They then adjust your home accordingly. 

All you have to do to trigger this intuitive ability of the thermostat is to manually turn the thermostat up and down a few times when you need a temperature change in your home, and it will learn what temperature you prefer and will then adjust the heat/cool settings automatically.

You conserve energy

As a changeover thermostat doesn’t keep temperatures unnecessarily too cold or too warm in your home you conserve energy and thus spend less money on electricity. 

Remote control

Almost all changeover thermostats can integrate with your smartphone, tablet, or computer so that you can control the temperature in your home even when you are not at home. 

Things to remember when installing an auto changeover thermostat

If you replace an existing thermostat, mount the new thermostat in the same place where the old one has been installed. 

For new installations, keep the following in mind:

  • Locate the thermostat on a wall in a room that is used often. 
  • Do not locate the thermostat in a corner or alcove, or behind a door where air circulation is poor, or where there are unusual heating conditions. Also, don’t locate it in unusual cooling conditions like in a draft from a stairwell, door, or window. 
  • Stay away from direct sunlight, a lamp, television, radiator, fireplace, hot water pipes in a wall, or where a stove is on the other side of the wall.
  • If you locate it in a damp area, it can lead to corrosion and shorten the thermostat’s life.
