a cooling temperature of 82°F until you
reenter your program. Setpoint tempera-
ture will not be displayed.
If a fresh 9 volt Energizer
installed, the program will be maintained for
about one week with no 24VAC power
present to the thermostat. See OPERAT-
ING YOUR THERMOSTAT.
4. Why can't I program the thermostat in
the AUTO mode?
The thermostat can only be programmed in
the HEAT and COOL modes. See PRO-
GRAMMING YOUR THERMOSTAT.
5. What can cause the thermostat display
to freeze or go blank?
A completely blank display may indicate
that power has been lost to the thermostat
and the backup battery is also dead. How-
®
alkaline battery is
ever, if there is power to the thermostat and
the display is blank or frozen, static dis-
charge is probably the cause.
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 remove the battery for at least
two minutes. After reinstalling the battery,
the thermostat will revert to the factory pre-
set program until you reprogram the ther-
mostat. If you don't want to reprogram the
thermostat immediately, press
til OFF is displayed and replace the thermo-
stat on the wall. Then press
the factory preset program.
