Honeywell thermostats are pure blessings for us and no wonder why people love them so much. Having the temperature right under control is one of the primary pillars of comfort and Honeywell thermostats take care of that perfectly well.
With its huge variety, starting from the ones with room temperature sensors to the brand new wifi-enabled model, these thermostats have been massively gaining popularity in recent times. But with a variety of models comes confusion about when and how you should change the batteries.
Well, if you have a similar question then you do not have to worry anymore because will take you through the entire process, starting from how to understand when it is time to change the batteries to the actual process of changing the batteries. Yes readers, today we are going to talk about Honeywell thermostats replacing batteries and everything related to it.
Let us Begin.
When Should You Change the Batteries?
Now speaking of Honeywell thermostats replacing batteries, although changing the batteries are very easy, sometimes with different models, there are some variations in the process. Hence, we would be helping you out in understanding those variations. Also, not all thermostat runs on batteries, so if you want to check if yours is a battery-run device or not then you should simply check if it has an LED display. If it does, then your device is running on batteries.
Now coming to the main question of Honeywell thermostats replacing batteries, when should you change the batteries of the thermostat. Generally, you need to change the batteries once a year. Although, the lifespan of the battery also largely depends on your use but generally, one set of batteries lasts for about a year. Also, once the batteries are about to expire, you get enough warnings from the device.
The first warning that you get is about 60 days before the battery expires. Here the LED screen flashes, low battery, or battery needs to be replaced repetitively on the screen. It is better to be prepared from then on and change the battery before your device completely dies. This notification will keep flashing not one day but continuously with breaks in between once you enter the last 60 days of the battery life.
There is a second type of warning, but this is the last stage of warning. Here the LED screen of the device turns black, and the device shuts down. This happens when the battery is about to be completely drained out of the system. However, in our opinion, you should not wait till the last minute to change the battery.
Now there are some thermostats where the batteries are only used as an extra backup. In this case, you might think that you do not have to change the batteries on time. However, that is a wrong approach. Even if the batteries are just a power backup for your device, you should still change them to keep your program setting intact.
In case you fail to charge these batteries, and go dead after their life span is over, you will see specific changes in the date and time setting of the thermostat, or you can even permanently lose the data.
How Do You Find Out the Model Number of The Thermostat and Why is It Necessary?
Next on, Honeywell thermostats replacing batteries. Let us talk about why it is necessary. As we were discussing before, each thermostat model has a different way of getting its batteries changed, so to know the right way to remove the battery from your device and replace it with the new ones, you will have to know about the model that you are using, that is, it is model number. This piece of information will ensure that you go in the right direction of doing the work.
Now that we know why you need to know your device’s model number, we will now talk about where you can spot it. If you are lucky enough then most devices have the number printed at the front of the model.
In this case, finding the model number is no big deal. However, if you see that your device does not have the model number printed on it then there can be 2 places where you can find it. It is either on the back of the device (you will have to remove it from the base to check it) or it is on the LED display.
If it is one the display itself then again you will not have to go through much trouble to find it but if it is on the back of the model, then there are a few more steps involved.
Steps to Find the Model Number on The Back of The Model
- The first and foremost thing that you should keep in mind is to remove it from the electric socket. Keeping it connected to a source of electricity increases the chances of you being exposed to live wire which can give you a fatal shock.
- The second step is to slide over the device off the base cover. Once it has been separated, you will find the model number written on the back of the device.
- Once you are done noting the number, slide it back into the base cover and put it back in its original place. Your work here is done.
In case you cannot find the model number of your thermostat in any of these three places then there is only one option left. Check out the box or the user-manual that came with it for the model number. You will surely find it there.
What Kind of Batteries Does Your Thermostat Require?
Next on Honeywell thermostats replacing batteries, we need to know the type of battery your thermostat needs. There are generally two types of batteries that are required for a thermostat. It is either AA or AAA.
Also, there are two types of covers when it comes to a thermostat. Some of them have a sliding cover, you can simply slide the device off the base plate just how you did to check the model number.
But let us say your device does not have a sliding compartment feature, then you will have to remove the cover plate from the device and gently separate it from the base plate.
Even doing this is not very difficult, you just might need some extra effort to do that.

Now, coming to the part of changing the batteries. First, let us tell you that this series of Honeywell thermostats will require 3 AAA batteries. Here are the following steps-
- The first step is basic, and this goes for all the thermostats, you need to switch off the current supply and it takes it out of the electrical outlet for your personal safety.
- After this, hold the base plate properly and pull off the front cover. Here holding the base plate will help you exert the required force to pull out the front cover.
- Once the front has been separated, you will see the battery compartment. There, replace the old batteries with the 3 new AAA batteries. Make sure you check the polarity of the batteries properly.
- Put the front cover back on the device, secure it in its position and plug the thermostat back in its position.
