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 flexibility
to design heating and cooling programs that fit your needs.
Features:
• Separate program for each day of the week with four separate
time/temperature periods per day
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• Backlit display
• LCD continuously displays setpoint, and alternately displays
time and room temperature
PRECAUTIONS
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.

!
CAUTION
To prevent electrical shock and/or equipment damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.

!
WARNING
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 circuits per the NEC code.
