9. The display is flashing BATTERY. What
does this mean?
The "AA" batteries installed in the thermostat
are low and should be replaced with fresh "AA"
Energizer
®
alkaline batteries. See OPERAT-
ING YOUR THERMOSTAT.
10. The thermostat beeps every few minutes.
What does this mean?
The thermostat will beep every five minutes
when the batteries are low and need replac-
ing. To override the beeping, press any button
on the keypad. The beeping will stop for 15
hours, then start again. You may again stop
the beeping by pressing any button on the
keypad. After turning the beep off three times,
the thermostat will quit beeping. However,
you risk losing your thermostat programming
if you continue to turn off the beep and do not
change the batteries. See OPERATING YOUR
THERMOSTAT.
11. The display shows a continuous (non-flash-
ing) 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.
12. Why won’t the compressor turn on, even
though the thermostat display is function-
ing 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 statement
at right. Then, if conditions permit, use the
button to move the temperature below
the setpoint temperature. See OPERATING
YOUR THERMOSTAT.
