The battery maintains the stored program in the event of a power failure. When attached to the wall with 24 VAC power applied, the thermostat will function normally without the battery. However, the program will be lost in the event of power interruption or failure if the battery is not installed. When power is restored, the thermostat will automatically main- tain a temperature of 64°F or a cooling temperature of 82°F (factory preprogrammed) as needed.
