Your
new White-Rodgers
Digital
Thermostat
uses the
technology of a solid-state
microcomputer
to provide precise
temperature control.
Features:
• Simultaneous
heat and cool setpoint storage
• Setpoint storage in case of power loss
• Pre-set temperature
control
• LCD continuously displays setpoint and room temperature
DESCRIPTION
• Continuous Backlit display option
• °F/°C convertibility
• Temperature range 45 ° to 90°F
• R, C, Y, W2, G, O/B, E, and L terminals for single or two-
transformer systems
• Optional "AA" batteries to provide continuous temperature
display during loss of AC power
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 (current limited) cir-
cuits per the NEC code. Failure to do so could cause a
fire hazard.
