these, then gently pivot the thermostat body

PARTS OF THE THERMOSTAT
The Back of The Thermostat Body
Turn the thermostat body over. On the back are
the 3 "AA" Energizer
®
alkaline batteries and the
two option switch groups (A and B).
1. The "AA" Energizer
®
alkaline batteries pro-
vide power to the thermostat when the 24vAC
power is interrupted (for example, when you
remove the thermostat from the wall for
programming). Fresh batteries will main-
tain the stored program for approximately a
year. If power loss is long enough for the
program to be lost, the thermostat will auto-
matically return to the factory programmed
temperatures (64°F heating and 82°F cool-
ing) when power is restored. You must
reprogram the thermostat if this happens.
If the word BATTERY is flashing in the
display window, the batteries are low and
should be replaced with fresh "AA" Ener-
gizer® alkaline batteries.
Before removing thermostat from the
wall to replace the batteries, remove
24vAC power from the thermostat at the
breaker/fuse box.
