OPERATING YOUR THERMOSTAT
Beforeyoubeginprogrammingyournewther-
mostat,youshouldbefamiliarwithitsfeatures
and with the display and the location and
operationofthethermostat buttons.Theinfor-
mation in this section will help you become
familiar with your thermostat so that you can
easily program it.
Your thermostat consists of two parts: the
thermostat body and the subbase.
Press
SYSTEM
HEAT-OFF-COOL-AUTO
to turn thermostat OFF
before removing or attaching the ther-
mostat body. Equipment damage and/
or personal injury could occur.
CAUTION
!
The subbase is attached to the wall, but you
can remove the thermostat body for easy pro-
gramming. To remove the thermostat body
from the subbase, grasp the thermostat body
and gently pull it out from the bottom of the
subbase, then pivot up. To attach the thermo-
stat body, line up the four terminal pins on the
upper section of the thermostat back with the
matching connector on the subbase. Insert
these, then gently pivot the thermostat body
downtoconnecttheninepinconnectorsonthe
lower portion of the thermostat back. Gently
push until the snap connectors engage. DO
NOT FORCE OR PRY THE THERMOSTAT,
as this may damage the unit.

PARTS OF THE THERMOSTAT
The Back of the Thermostat Body
Turn the thermostat body over. On the back
are the 9 volt Energizer®alkaline battery and
the option switches.
1. The 9 volt Energizer®alkaline battery pro-
vides power to the thermostat when the
24 VACpowerisinterrupted(forexample,
whenyou remove the thermostat from the
wall for programming). A fresh battery will
maintain the stored program for approxi-
mately one week. If power loss is long
enough for the program to be lost, the
thermostat will automatically maintain a
factory preprogrammed heating tempera-
ture of 64°F and a cooling temperature of
82°F after power is restored. You must
reprogram the thermostat if this happens.
If the word BAT is flashing in the display
window, the battery is low and should be
replaced with a fresh 9 volt Energizer®
alkaline battery. The battery will provide
power for all functions except the display
lightandaudioprompting,whichworkonly
on 24 VAC power. If the word BAT is
displayedcontinuously(non-flashing),the
thermostat is not being supplied with
24 VAC power and is being powered by
the battery alone.
