To prevent further static discharge prob- lems, touch another object to release static build-up before touching the thermostat. See OPERATING YOUR THERMOSTAT.

6.The display is flashing BATTERY. What does this mean?

The "AA" batteries installed in the thermo- stat are low and should be replaced with fresh "AA" Energizer® alkaline batteries. See

OPERATING YOUR THERMOSTAT.

7.The display shows a continuous (non- flashing) BATTERY. What does this mean?

The thermostat is not being supplied with 24vAC power. The thermostat is operating on battery power alone. See OPERATING YOUR THERMOSTAT.

8.Why won’t the compressor turn on, even though the thermostat display is func- tioning normally?

Either the compressor lockout feature is in operation or the thermostat is not currently calling for cool. Wait about 5 minutes for the compressor lockout to expire. If the system is still not running, read the cautionary state- ment at right. Then, if conditions permit,

use the Manual background button to move the tempera- ture below the setpoint temperature. See

OPERATING YOUR THERMOSTAT.
