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 and the two option switch groups (A and B).

1.The “AA” Energizer® alkaline batteries pro- vide 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 ap- proximately a year. If power loss is long enough for the program to be lost, the

thermostat will automatically return to the factory programmed temperatures (64°F heating and 82°F cooling) when power is restored. You must reprogram the thermo- stat if this happens.

If the word BATTERY is flashing in the display window, the batteries are low and should be replaced with fresh “AA” Ener- gizer® alkaline batteries.
