PARTS OF THE THERMOSTAT
The Back of The Thermostat Body
Turn the thermostat body over. On the back are the 3 “AA” Energizer® alkaline batteries.
The “AA” Energizer® alkaline batteries provide power to the thermostat when the 24 VAC power is interrupted (for example, when you remove the thermostat from the wall for programming). Fresh batteries will maintain the stored program for approximately a year. If power loss is long enough for the program to be lost, the thermo- stat will automatically return to the factory pro- grammed temperatures (64°F heating and 82°F cooling) when power is restored. You must reprogram the thermostat if this happens.
If the word BATTERY is flashing in the display window, the batteries are low and should be replaced with fresh “AA” Energizer® alkaline batteries.
