How to Change a Honeywell Thermostat’s Batteries

Thermostat batteries always seem to die at the wrong time. You get one scorching day after a cold spell and go to turn the thermostat down and… The batteries are flat. Or you get some unexpected cold days at the end of the summer. You go to turn up the heat on the thermostat and… Again, the batteries are as dead as a doormat.

Now, you could follow the steps printed in your thermostat’s user manual to change the batteries. But if your shredder has been working as hard as mine has recently, you’ll know that that is no longer an option. 

But not to worry! As included in this article is the very best set of instructions. These will help you to change the batteries of your Honeywell thermostat. It is ideal for changing a thermostat with both the basic pull or hinge design. Let’s get started!

#1 Turn the Power Off

Before you get cracking, make sure you turn your thermostat off. There should be an on/off switch on the face of the thermostat for you to do so. This should prevent the thermostat from unsyncing itself in case it malfunctions when you remove the batteries. 

Now turn the electricity off to the thermostat at the circuit breakers. 

#2 Remove the Battery Compartment From the Baseplate

This step will change depending on the model of your Honeywell thermostat. Take a look at the table below that will show you the step that is right for your model. 

#3 Remove the Old Batteries

Remove the old batteries from the faceplate. Make a note of the old battery size. Then dispose of the batteries.

#4 Replace the Batteries 

Replace the old batteries with new ones. Most Honeywell thermostats take two AA batteries. But to be safe, replace your batteries with the same size that were in there before.  

#5 Replace the Battery Compartment to the Baseplate

This step will also change depending on the model of your Honeywell thermostat. Take a look at the table below that will show you the step that is right for your model:

#6 Turn the Power On

Snap back the cover plate back to wall plate and turn the system on.

Start by turning the power back on at the circuit breakers. Then turn the thermostat on with the on/off button. Wait a minute for a new cycle to begin on the display. After one minute, your thermostat will restart and will be ready to use again. 

You’ve finished! Now do a celebratory happy dance around the living room (mandatory step).

How Do You Reset a Honeywell Thermostat

There are a few reasons why you may need to reset your thermostat from time to time. Here are some of them:

• Your thermostat is not regulating your home temperature as well as it did before. Do you find yourself cranking your thermostat up and down in an attempt to find that happy medium? Then don’t call the plumbers out just yet. A restart may be all your thermostat needs to kick it back into shape. 
• You’ve recently had a power cut. Power outages could affect the operation of your thermostat. After a power cut, you may find it beneficial to restart your thermostat. 
• You’ve been away from home. Many homeowners choose to turn their thermostats down 10 to 15 degrees to save money on their electric bills while on vacation.
