Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.
Thermostat installation and all components of the
system shall conform to Class II (current limited) cir-
cuits per the NEC code. Failure to do so may cause a
fire hazard.
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
Your new White-Rodgers 7-Day Digital Thermostat uses the
technology of a solid-state microcomputer to provide precise
time/temperature control. This thermostat offers you the flexibil-
ity to design heating and cooling programs that fit your needs.
Features:
• Separate program for each day of the week with four separate
time/temperature settings per day
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• LCD continuously displays setpoint, and alternately dis-
plays time and room temperature
• Backlit display
• Temperature override until next program period
• Manual program override (HOLD temperature)
• °F/°C convertibility
• Temperature range 45° to 90°F
• RC, RH, W, Y, G , O and B terminals
• B and O terminals for single stage heat pumps (no auxiliary
heat) or damper operation
• Program storage in case of power loss.
• Battery powered (2 "AA" Energizer
®
alkaline batteries in-
cluded)

INSTALLATION AND
OPERATION INSTRUCTIONS
PRECAUTIONS
CAUTION
!
This thermostat is intended for use with a low voltage system;
do not use this thermostat with a line voltage system. If in doubt
about whether your wiring is millivolt, line, or low voltage, have
it inspected by a qualified heating and air conditioning contractor
or electrician.
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 components could cause
the control to malfunction.
To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system at main fuse
or circuit breaker box until installation is complete.
WARNING
!
Operator: Save these instructions for future use!
"Loading the manual" means you need to wait until the file loads and becomes available for online reading. Some manuals are very large, and the time they take to appear depends on your internet speed.
