Batteries should be replaced at least once a year. Replacing the batteries helps to prevent leakage that can corrode and damage the thermostat. Replace the batteries when you see the low battery indicator on your thermostat. If the batteries are allowed to deplete completely, your heating and air conditioning system cannot function properly.


If you will be away from home for a month or more, consider replacing the batteries before you go to ensure continued operation while you are gone.


To replace the batteries in your Homelife and Automation thermostat, you need three AA batteries. No tools are required to replace the batteries. Follow the steps below to properly replace your thermostat batteries.

If the thermostat batteries fail with the heat OFF, this can result in no heat and possible frozen or broken pipes and water damage. If the thermostat batteries fail with the cool OFF, this can result in no cooling and could cause possible damage or excessive temperatures.
