Replacing the batteries in your Honeywell thermostat is a simple task that can be completed in a few minutes. By following these easy steps, you can ensure that your thermostat is functioning properly and keeping your home comfortable. Additionally, replacing the batteries regularly will help to extend the life of your thermostat and prevent any unexpected interruptions in its operation.
Before you begin, you will need to gather a few tools. These include a small Phillips head screwdriver, a new set of batteries (either AA or AAA, depending on your thermostat model), and a clean cloth. Once you have your tools assembled, you can begin the process of replacing the batteries. First, locate the battery compartment on the back of the thermostat. Depending on your model, the battery compartment may be held in place by a screw or a latch. Use the screwdriver to remove the screw or open the latch, and then carefully lift the battery compartment out of the thermostat.
Identifying the Correct Battery Type
When replacing batteries in a Honeywell thermostat, selecting the correct type is crucial to ensure optimal performance and maintain the accuracy of temperature readings.
Identifying the Correct Battery Size and Type
Honeywell thermostats typically use either of two common battery types:
AA Batteries
* Cylindrical cells approximately 1.5 inches (38.1 mm) long and 0.5 inches (12.7 mm) in diameter.
* Usually used in older Honeywell thermostats or those requiring multiple batteries.
CR2032 Batteries
* Coin-shaped cells with a diameter of 0.75 inches (19 mm) and a height of 0.1 inches (2.5 mm).
* Found in newer Honeywell thermostats and those designed for compact spaces.
The specific battery type required for your Honeywell thermostat can vary depending on the model. To determine the correct type, refer to the thermostat’s user manual or inspect the battery compartment where the old batteries were housed. If the information is not available, contact Honeywell customer support for assistance.
| Battery Type | Shape | Size |
|---|---|---|
| AA | Cylindrical | 1.5 inches x 0.5 inches |
| CR2032 | Coin-shaped | 0.75 inches x 0.1 inches |
Removing the Old Batteries
To replace the batteries in your Honeywell thermostat, it is important to first locate the battery compartment. Most Honeywell thermostats have the battery compartment located on the back or bottom of the device. Once you have located the battery compartment, follow these steps to remove the old batteries.
Safety Precautions
Before you begin, make sure that the thermostat is turned off and that the power to the heating and cooling system is turned off. This will help to prevent any electrical shocks or damage to the thermostat.
Steps to Remove the Old Batteries
| Step | Instructions |
|---|---|
| 1. | Locate the battery compartment on the back or bottom of the thermostat. |
| 2. | Open the battery compartment by sliding the latch or removing the screws. |
| 3. | Remove the old batteries from the compartment. |
Inserting the New Batteries
Make sure you have the correct batteries for your thermostat. The type of batteries required will vary depending on the model of your thermostat. For example, the Honeywell TH4110B thermostat requires two AA batteries, while the Honeywell RTH9580WF thermostat requires two AAA batteries. Once you have the correct batteries, follow these steps to insert them:
1. Open the battery compartment. The battery compartment is usually located on the back or bottom of the thermostat.
2. Remove the old batteries.
3. Insert the new batteries into the battery compartment. Make sure that the positive (+) and negative (-) terminals of the batteries are aligned correctly. The terminals will be marked on the inside of the battery compartment.
| Battery Type | Thermostat Model |
|---|---|
| AA | Honeywell TH4110B |
| AAA | Honeywell RTH9580WF |
4. Close the battery compartment. The thermostat should now be powered on and ready to use.
Resetting the Thermostat
Resetting your Honeywell thermostat is a simple process that can be completed in a few minutes. Here are the steps to follow:
Step 1: Remove the batteries
To remove the batteries, simply pull the battery cover off the back of the thermostat. The batteries are located inside the battery compartment.
Step 2: Insert the new batteries
Insert the new batteries into the battery compartment, making sure that they are facing the correct direction. The positive (+) terminal of the battery should be facing up, and the negative (-) terminal should be facing down.
Step 3: Replace the battery cover
Replace the battery cover by sliding it back into place until it clicks into place.
Step 4: Restore the thermostat settings
To restore the thermostat settings, hold down the “Reset” button for 10 seconds. The thermostat will display “rSt” to indicate that it is resetting. Once the reset is complete, the thermostat will display the current time and temperature.
Note:If you are having trouble restoring the thermostat settings, you may need to contact Honeywell customer support.

If the thermostat is displaying an error message, check the manual for the specific error code. The error code will usually provide you with more information about the problem and how to fix it.
4. The thermostat is not controlling the temperature.
If the thermostat is not controlling the temperature, check the following:
- Make sure the thermostat is set to the correct mode (heat, cool, or auto).
- Make sure the thermostat is set to the correct temperature.
- Make sure the thermostat is not in a location where it is exposed to drafts or direct sunlight.
- Check the wiring connections to the thermostat.
5. The thermostat is draining batteries quickly.
If the thermostat is draining batteries quickly, there may be a problem with the wiring or the thermostat itself. Check the wiring connections to the thermostat. If the wiring is correct, the thermostat may need to be replaced.
| Possible Cause | Solution |
|---|---|
| Batteries inserted incorrectly | Check the polarity of the batteries and insert them correctly. |
| Corroded battery terminals | Clean the battery terminals with a cotton swab dipped in vinegar. |
| Loose wiring connections | Tighten the wiring connections to the thermostat. |
Precautions for Battery Replacement
Before replacing the batteries in your Honeywell thermostat, it’s crucial to take necessary precautions to ensure the process is carried out safely and efficiently. By following these guidelines, you can minimize potential risks and ensure the smooth operation of your thermostat.
1. Safety First
