During periods of low humidity (especially
during cold weather), you may feel or see a
spark discharge when you touch the thermo-
stat. This may cause the program to be lost or
the thermostat to display incorrectly. To cor-
rect this, remove the thermostat from the wall
and disconnect the battery. Wait about two
minutes, 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
immediately, press
SYSTEM
HEAT-OFF-COOL-AUTO
until OFF is dis-
played and replace the thermostat on the wall.
Then press
RUN
PRGM
to begin the factory preset
program. Or you may reprogram the thermo-
stat, then replace it on the wall.
To prevent further static discharge problems,
touch another object to release static build-up
before touching the thermostat. See OPER-
ATING YOUR THERMOSTAT.
8. 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 tem-
perature you select (for example, if 70°F is
your lowest selected cooling temperature, you
cannot select a heating 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 PRO-
GRAMMING YOUR THERMOSTAT.
