During periods of low humidity (especially
during cold weather), you may feel or see
a spark discharge when you touch the
thermostat. This may cause the program
to be lost or the thermostat to display
incorrectly. To correct this, remove the
thermostat from the wall and disconnect
the battery. Wait about one minute, then
reconnect the battery. The thermostat will
revert to the factory preset program until
you reprogram the thermostat. If you don’t
want to reprogram the thermostat immedi-
ately, press SYSTEM
SWITCH
until OFF is displayed
and replace the thermostat on the wall.
Then press RUN
PRGM
to begin the factory preset
program. Or you may reprogram the ther-
mostat, then replace it on the wall.
To prevent further static discharge prob-
lems, touch another object to release static
build-up before touching the 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
cooling temperature, you cannot select a
heating 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.
