PARTS OF THE THERMOSTAT

The Back of the Thermostat Body

Turn the thermostat body over. On the back are the 9 volt Energizer® alkaline battery and the option switches.

1.The 9 volt Energizer® alkaline battery pro- vides power to the thermostat when the 24 VAC power is interrupted (for example, when you remove the thermostat from the wall for programming). A fresh battery will maintain the stored program for approxi- mately one week. If power loss is long enough for the program to be lost, the thermostat will automatically maintain a fac-

tory preprogrammed heating temperature of 64°F and a cooling temperature of 82°F after power is restored. You must repro- gram the thermostat if this happens.

If the word BAT is flashing in the display window, the battery is low and should be replaced with a fresh 9 volt Energizer® alkaline battery. The battery will provide power for all functions except the display
