FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
Your new Digital Thermostat uses the technology of a solid-state
microcomputer to provide precise temperature 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 loss
2 "AA" 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 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.
A WARNING
Do not use on circuits exceeding specified voitage.
Higher voitage will damage control and could cause
shock or fire hazard.
Do not short out terminais on gas vaive or primary
controi to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.
Thermostat instaiiation and all components of the sys­
tem shall conform to Class II circuits per the NEC code.
A
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.
