GENERAL

Carrier's Comfort Pro programmable thermostats are wall-
mounted, low-voltage thermostats that maintain room tempera-
ture by controlling the operation of a heating and/or air condi-
tioning system (Fig. 1). The 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, backlighting, and built-in installer test.
The programming interface is a one touch interface, with
the comfort selections Occupied, Unoccupied, and Limit (En-
ergy Savings Mode). The user can adjust the heating and/or
cooling set points for each of the three comfort selections.
