PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
Your new White-Rodgers Digital Thermostat uses the technol-
ogy of a solid-state microcomputer to provide precise tempera-
ture control.
Features:
• Simultaneous heat and cool setpoint storage
• Pre-set temperature control
• Backlit display
• LCD continuously displays setpoint and room temperature
• °F/°C convertibility
• Temperature range 45° to 90°F
• RC, RH, C, W, Y, G, O and B terminals
• Optional C terminal (Dual Power option)
• B and O terminals for single stage heat pumps (no auxiliary
heat) or damper operation
• Setpoint storage in case of power toss
®
• 2 "AA" Energizer alkaline batteries included
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 mittivolt, line, or tow 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.
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.
