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®alkalinebatteriesprovide
power to the thermostat when the 24vAC
power is interrupted (for example, when you
remove the thermostat from the wall for pro-
gramming). Fresh batteries will maintain the
stored program for approximately a year. If
power loss is long enough for the program to
be lost, the thermostat will automatically re-
turn to the factory programmed temperatures
(64°F heating and 82°F cooling) when power
is restored. You must reprogram the thermo-
stat if this happens.
IfthewordBATTERYisflashinginthedisplay
window, the batteries are low and should be
replaced with fresh "AA" Energizer® alkaline
batteries.
Before removing thermostat from the wall
to replace the batteries, remove 24vAC
power from the thermostat at the breaker/
fuse box.
2. You may adjust the option switches for EMR,
keypadlockout,andautomaticchangeoverfrom
heat to cool (see OPERATING FEATURES).
