What You’ll Need:

For this project, you will need a Phillips head screwdriver, two AA batteries, and an owner’s manual or instructions specific to your Honeywell thermostat.

• Step 1:

Locate and remove the battery compartment, this can usually be found on the back or side of your Honeywell thermostat.

Use a Phillips head screwdriver to carefully unscrew the screws that are securing the battery compartment in place. Once you have removed all of the screws, the cover should come off easily.

• Step 2:

Before inserting new batteries, it is important to safely dispose of the old ones.

• Step 3:

Insert two AA batteries into the housing and make sure they click into place. The positive and negative ends should be facing the correct direction.

Refer to your owner’s manual for specifics regarding which way the batteries should be placed.

• Step 4:

Once you have inserted the new batteries, it is time to reattach the battery compartment cover. Simply reverse Step 1 and securely tighten the screws using a Phillips head screwdriver.

After the battery compartment is secured, you should be able to power up your Honeywell thermostat and enjoy it once again.

• Step 5:

Reconnect power to your device either plugging it in or turning on its circuit breaker depending on how you have previously powered it up and allow for around 10 seconds before using it again so that any information stored can be accessed properly by its display screen.

• Step 6:

Double check that all thermostat wiring is secure within their appropriate slots before using or moving on with any further programming as even a small disconnection could cause problems while trying to use or adjust settings later down the line.
