GENERAL

Carrier’s Comfort Pro programmable thermostats are wall-

mounted, low-voltage thermostats which maintain room tem-

perature by controlling the operation of a heating and/or air

conditioning system. This thermostat can be used with a heat

pump, air conditioner or water source heat pump operation. A

variety of features are provided including battery operation,

separate heating and cooling set points, auto changeover, key-

pad lockout, and backlighting. Programming is available for ei-

ther 2 or 4 periods per day. The programming interface is a one

touch interface, with the Comfort selections Occupied, Unoc-

cupied, and Limit (Energy Savings Mode). The user can adjust

the heating and/or cooling set points for each of the three com-

fort selections.
