Battery Replacement
If your thermostat has batteries, a low battery warning flashes on the home screen for approximately 30 days.
IMPORTANT − Batteries should be replaced once per year to prevent leakage and to prevent loss of battery back−up in a power outtage. You may also wish to replace the batteries prior to leaving your home for more than a month.
1 − When the low battery indicator is flashing, replace the batteries promptly with three fresh AAA alkaline batteries.
2 − Remove the thermostat from the wallplate by pulling straight out.
