During periods of low humidity (especially
during cold weather), you may feel or see a
spark discharge when you touch the ther-
mostat. 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 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.

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 68°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.
