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 provide

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.

If the word BATTERY is flashing in the display

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,

keypad lockout, and automatic changeover from

heat to cool (see OPERATING FEATURES).
