SAFETY CONSIDERATIONS

Read and follow manufacturer instructions carefully. Fol-

low all local electrical codes during installation. All wiring

must conform to local and national electrical codes. Improper

wiring or installation may damage thermostat.

Recognize safety information. This is the safety alert sym-

bol

 . When the safety alert symbol is present on equipment

or in the instruction manual, be alert to the potential for person-

al injury.

Understand the signal words DANGER, WARNING, and

CAUTION. These words are used with the safety alert symbol.

DANGER identifies the most serious hazards which will result

in severe personal injury or death. WARNING signifies a haz-

ard which could result in personal injury or death. CAUTION

is used to identify unsafe practices which would result in minor

personal injury or property damage. 

GENERAL

Carrier’s Comfort Pro non-programmable thermostats are

wall-mounted, low-voltage thermostats that maintain room

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

conditioning system (Fig. 1). This thermostat can be used with

a heat pump, air conditioner or water source heat pump opera-

tion. A variety of features are provided including battery opera-

tion, separate heating and cooling set points, auto changeover,

keypad lockout, backlighting, and built-in installer test. 

This Installation Instruction covers installation, configura-

tion, and start-up of the Comfort Pro non-programmable ther-

mostat. For operational details, consult the Owner's Manual for

this specific thermostat.

PACKAGE CONTENTS

1 — Thermostat
1 — Backplate (mounting base)
2 — Screws and anchors

INSTALLATION CONSIDERATIONS

Power  — 

The thermostat will obtain full operating power

one of two ways: full 24 volt AC (50/60 Hz) power via the Rc/

Rh and C terminals or two AA alkaline batteries. The 24 vac

operation is preferred, if available. Battery operation is used

when there are not enough wires to support 24 vac operation.

IMPORTANT: Read entire instruction before installing

the thermostat.
