discharge 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 disconnect the batteries. Wait
about two minutes, then reconnect the bat-
teries. The thermostat will revert to the fac-
tory preset program until you reprogram the
thermostat. If you don’t want to reprogram
the thermostat immediately, press

SWITCH
until OFF is displayed and replace the ther-
mostat on the wall. Press
SYSTEM
SWITCH
until
HEAT or COOL is displayed, then press

to begin the factory preset program. Or
you may reprogram the thermostat, 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.
