OPERATINGYOURTHERMOSTAT
Before you begin programming your thermo-
stat, you should be familiar with its features
and with the display and the location and
operation of the thermostat buttons. The in-
formation in this section will help you become
familiar with your new thermostat so that you
can easily program it.
Your thermostat consists of two parts: the ther-
mostat body and the subbase.
Remove power from the system at the
circuit breaker/fuse box before remov-
ing or attaching the thermostat body.
Equipment damage and/or personal in-
jury could occur.
Thesubbaseisattachedtothewall,butyoucan
remove the thermostat body for easy program-
ming. To remove the thermostat body from the
subbase, grasp the thermostat body and gently
pull it straight out from the subbase. To attach
the thermostat body, line up the two terminal
pinsonthelowersectionofthethermostatback
with the matching connector on the subbase.
Insert these, then gently pivot the thermostat
bodyuptoconnectthesixpinconnectorsonthe
upper portion of the thermostat back. Gently
push until the snap connectors engage. DO
NOTFORCEORPRYTHETHERMOSTAT,as
this may damage the unit.

PARTS OF THE THERMOSTAT
The Back of The Thermostat Body
Turnthe thermostat body over.On the back are
the 3 “AA” Energizer®alkaline batteries.
The “AA” Energizer®alkaline batteries provide
powertothethermostatwhenthe24VACpower
is interrupted (for example, when you remove
the thermostat from the wall for programming).
Freshbatterieswillmaintainthestoredprogram
for approximately a year. If power loss is long
enough for the program to be lost, the thermo-
stat will automatically return to the factory pro-
grammedtemperatures(64°Fheatingand82°F
cooling) when power is restored. You must
reprogram the thermostat if this happens.
If the word BATTERY is flashing in the display
