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 provide power to the thermostat when the 24vAC power is interrupted (for example, when you remove the thermostat from the wall for pro- gramming). Fresh batteries will maintain the stored program for approximately a year. If power loss is long enough for the program to be lost, the thermostat will automatically re-

turn 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" Energizer® alkaline batteries.

!CAUTION

Before removing thermostat from the wall to replace the batteries, remove 24vAC power from the thermostat at the breaker/ fuse box.

2.You may adjust the option switches for EMR, keypad lockout, and automatic changeover from heat to cool (see OPERATING FEATURES).
