If a fresh 9 volt Energizer

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-
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
thermostat. This may cause the program to
be lost or the thermostat to display incor-
rectly. To correct this, remove the thermo-
stat from the wall and disconnect the bat-
tery. Wait about two minutes, then re-
connect 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-
