To correct this, remove the thermostat from
the wall and disconnect the battery. Wait
about one minute, then reconnect the bat-
tery. The thermostat will revert to the factory
preset program until you reprogram the
thermostat. If you don’t want to reprogram
the thermostat immediately, press SYSTEM
HEAT - OFF - COOL - AUTO
until OFF is displayed and replace the ther-
mostat on the wall. Then press RUN
PRGM
to
begin the factory preset program. Or you
may reprogram the thermostat, then re-
place it on the wall.
To prevent further static discharge prob-
lems, touch another object to release static
build-up before touching the thermostat.
See OPERATING YOUR THERMOSTAT.
7. Why won’t the setpoint temperature go
to the temperature I want?
In the AUTO mode, the highest heating
setpoint temperature you select must be at
least 1
°
F lower than the lowest cooling
setpoint temperature you select (for ex-
ample, if 70
°
F is your lowest selected cool-
ing temperature, you cannot select a heat-
ing temperature any higher than 69
°
F). If
such a conflict exists, you must set the
lowest cooling temperature higher in order
to set the heating temperature higher. To
set a lower cooling temperature, you must
select a lower heating temperature. See
PROGRAMMING YOUR THERMOSTAT.
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?
