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.

Operator: Save these instructions for future use!

WHITE-RODGERS

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 program

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 automatically main-
tain a factory preprogrammed heating temperature of
64

°

F or a cooling temperature of 82

°

F.

DESCRIPTION

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.

Do not exceed the specification ratings.
