8. Why doesn’t the display light come on
when I press a button? Why don’t I hear
a beep when I press a button?
The display light and audio prompting
(beep) only work when the thermostat is
on the wall and 24 VAC power is present
to the thermostat. See OPERATING
YOUR THERMOSTAT.
9. The display is flashing BATTERY. What
does this mean?
The 9 volt battery installed in the thermostat
is low and should be replaced with a fresh 9
volt Energizer
®
alkaline battery. See OPER-
ATING YOUR THERMOSTAT.
10. Why won’t the system 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 heat or cool. Wait about 5 minutes
for the compressor lockout to expire. If the
system is still not running, read the caution-
ary statement at the right. Then, if condi-
tions permit, use the or buttons
to move the temperature above or below the
setpoint temperature. See OPERATING
YOUR THERMOSTAT.
