Your new White-Rodgers Digital Thermostat uses the technol-
ogy of a solid-state microcomputer to provide precise tempera-
ture control.
• Simultaneous heat and cool setpoint storage
• Pre-set temperature control
• Backlit display
• LCD continuously displays setpoint and room temperature
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 contrac-
tor 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 damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.
Electrical Rating:
8 to 30 VAC 50/60 Hz. or D.C.
0.05 to 1.0 Amps (Load per terminal)
1.5 Amps Maximum Total Load (All terminals combined)
Setpoint Temperature Range:
45°F to 90°F (7°C to 32°C)
Operating Ambient Temperature Range:
32°F to 105°F
Operating Humidity Range:
0 to 90% RH (non-condensing)
Shipping Temperature Range:
-4°F to 150°F

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 sys-
tem shall conform to Class II circuits per the NEC code.
