FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY

BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE

PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

This wall-mounted, low voltage thermostat maintains

room temperature by controlling the operation of heating

and cooling systems. The user may program up to four

time/temperature settings per 24 hour period. The ther-

mostat stores independent heating and cooling programs

for each day of the week. The thermostat will store both

heating and cooling programs simultaneously. Three

"AA" Energizer

batteries will maintain the stored pro-

gram for approximately one year, if incoming power

should fail. If power failure is extensive and the program

is lost, after power restoration, the thermostat will auto-

matically maintain a factory preprogrammed heating tem-

perature of 64°F or a cooling temperature of 82°F.

PRECAUTIONS

If in doubt about whether your wiring is millivolt, line, or low

voltage, have it inspected by a qualified heating and air

conditioning contractor, electrician, or someone familiar

with basic electricity and wiring.

WHITE-RODGERS

Do not exceed the specification ratings.

All wiring must conform to local and national electrical

codes and ordinances.

This control is a precision instrument, and should be

handled carefully. Rough handling or distorting compo-

nents could cause the control to malfunction.

To prevent electrical shock and/or equipment

damage, disconnect electric power to system, at

main fuse or circuit breaker box, until installation

is complete.

Do not use on circuits exceeding specified volt-

age. Higher voltage will damage control and

could cause shock or fire hazard.

Do not short out terminals on gas valve or pri-

mary control to test. Short or incorrect wiring will

burn out thermostat and could cause personal

injury and/or property damage.
