the thermostat immediately, press SYSTEM

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
button to move the tempera-
ture below the setpoint temperature. See
OPERATING YOUR THERMOSTAT.
