•Preprogrammed temperature control

•LCD continuously displays setpoint, and alternately dis- plays time and room temperature

•Backlit display

•Temperature override until next program period

•Manual program override (HOLD temperature)

•°F/°C convertibility

•Temperature range 45° to 90°F

•RC, RH, W, Y, G , O and B terminals

•B and O terminals for single stage heat pumps (no auxiliary heat) or damper operation

•Program storage in case of power loss.

•Battery powered (2 "AA" Energizer® alkaline batteries in- cluded)

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 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.

!WARNING

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 may cause a fire hazard.
