FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
Your new White-Rodgers 5-Day/1-Day/1-Day Digital Thermo-
stat 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 5-day (weekday) and 1-day/1-day (Saturday/Sunday)
programming with four separate time/temperature periods per day
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• Optional battery back-up for AC power loss
This thermostat is intended for use with a low voltage NEC
Class II 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 dam-
age, disconnect electric power to system at main fuse
or circuit breaker box until installation is complete.

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)
circuits per the NEC code. Failure to do so could cause
a fire hazard.
