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 pow-
er 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 batter-
ies.
2 − Remove the thermostat from the wallplate by pulling
straight out.

Questions and answers
In wiping off my thermostat screen with my fingers, I didn't spray anything on the screen, or any moisture. I **** now not able to bring anything back on the screen, other than the system and the current temp. I have changed the batteries and cleaned off the terminals.The three of five boxes on the bottom are clock, screen and more. I can't find anything in the manual addressing this. Help please.
Try pressing and holding the center blank key for approximately five seconds until the screen changes. If the issue persists, check the thermostat’s power supply and ensure it is properly connected. If necessary, reset the thermostat by following the manufacturer’s instructions.
