this symbol on the equipment and in the instruction manual, be alert to the

potential for personal 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 hazard which could result in personal injury or death. CAUTION is

usedto identify unsafe practices which may result in minor personal injury or

product and property damage. NOTE is used to highlight suggestions which will

result in enhanced installation, reliability, or operation.

INTRODUCTION

Carrier's Comfort 'M Series programmable thermostats are wall-mounted,

low-voltage thermostats which maintain room temperature by controlling the

operation of a heating and/or air conditioning system. Both heat pump and air

conditioner models are available, each in programmable and non-programmable

versions. A variety of features are provided including battery operation, separate

heating and cooling setpoints, auto changeover, keypad lockout, backlighting,

and built-in installer test. Programming features include 7-day (all days the

same) and 5/2 (Mon-Fri and Sat-Sun) with 2 or 4 periods per day.

This Installation Instruction covers installation, configuration, and startup of all

four versions of the Comfort Series line of thermostats. For operational details,

consult the Owner's Manual for the specific thermostat you are installing.

INSTALLATION CONSIDERATIONS

Models

There are four models in the Comfort Series: programmable and

non-programmable, AC and HR Models TC-PAC and TC-NAC are designed for

AC systems, controlling one stage of cooling and one stage of heating. They will not

operate a heat pump. Models TC-PHP and TC-NHP are designed for HP systems,

controlling one stage of cooling and two stages of heating. They can be converted to

AC operation. Select the appropriate model for the intended application.

Power

All Comfort Series models are dual powered. They can operate from batteries or

24VAC power. Operation from 24VAC is preferred if available. Battery

operation is used when there are not enough wires to support 24VAC operation

or when "armchair programming" is desired. For an AC system, up to six wires

are needed for 24VAC operation and one less wire for battery operation. For a

HP system, up to seven wires are needed for 24VAC operation and one less wire

would be sufficient for battery operation. For heat only operation with batteries,

only two wires are required. When battery operation is used, the C terminal does

not need to be connected.

Provision is also made for separate heating and cooling transformers via separable Rc

and Rh terminals which are connected via factory-installed jumper wire.

INSTALLATION

Step 1-- Thermostat Location

•Approximately 5 fl (l.5m) from floor.

• Close to or in a frequently used room, preferably on an inside

partitioning wall.

• On a section of wall without pipes or duct work.

Thermostat should NOT be mounted

• Close to a window, on an outside wall, or next to a door leading to the

outside.

• Exposed to direct light or heat from the sun, a lamp, fireplace, or other

temperature-radiating objects which could cause a false reading.

• Close to or in direct airflow from supply registers and return-air

registers.

• In areas with poor air circulation, such as behind a door or in an

alcove.

Step 2-- Install Thermostat

ELECTRICAL OPERATION HAZARD

Failure to follow this warning could result in personal injury

or death.

Before installing thermostat, turn off all power to equipment.

There may be more than one power disconnect.

1. Turn OFF all power to unit.

2. If an existing thermostat is being replaced:

a. Remove existing thermostat from wall.

b. Disconnect wires from existing thermostat, one at a time. Be careful

not to allow wires to fall back into the wall.

c. As each wire is disconnected, record wire color and terminal marking.

d. Discard or recycle old thermostat.

ENVIRONMENTAL HAZARD

Failure to follow this caution may result in environmental

damage.

Mercury is a hazardous waste. Federal regulations require that

Mercury be disposed of properly.

3. Open thermostat (mounting base) to expose mounting holes. The base

can be removed to simplify mounting. Press the thumb release at the top

When power is applied, all display icons are lit for 2 seconds to test the display.

Following this, the equipment type for which the thermostat is configured is

displayed for an additional 2 seconds. It will be one of HR H2, AC, A2, H or C (see

explanation under Step 3, Option 01 below). A HP thermostat configured to operate

an AC (see Option I below) will display AC. An AC thermostat cannot display HR

NOTE: If a common wire has not been connected, two AA batteries must be

used to power the thermostat.

Step 3-- Set Thermostat Configuration

Configuration options enable the installer to configure the thermostat for a particular

installation. Most are not presented to the homeowner and therefore must be properly

set by the installer. (Only those marked with an asterisk * below are available to the

homeowner.)Followingisalistoftheoptionsavailable,anexplanationoftheir

ToEnterthe Configuration Mode:

Press and hold the FAN key for about 10 seconds until the display changes so

that only two pairs of digits are showing. The left (programmable version) or the

large upper (non-programmable version) display shows the configuration

number and the right (programmable version) or small lower

(non-programmable version) shows the configuration setting. Configuration

number will be flashing which means it can be adjusted using the UP and

DOWN keys. To cause the opposite pair to flash (to be adjustable), press the

MODE key. Successive presses of the MODE key alternate between the

configuration number and the configuration setting. To exit the configuration

mode, press the FAN key. If no key is pressed for 3 minutes, the configuration

mode will automatically exit, returning the thermostat to normal operation.

Configuration Options - Selection:

Option 01 - Equipment type

Selections: with HP thermostat: HP, H2, AC, A2, H, C

with AC thermostat: AC, A2, H, C

HP controls 1 speed heat pump with 1 stage of aux heat.

A2 controls two stages of cooling and one stage of furnace heat.

H2 controls a 2 Speed HP with 1 stage of aux heat.

AC controls 1 speed air conditioner with 1 stage of heat.

H operates a heat _ system: furnace or fan coil only; no outdoor unit.

C operates a cool _ system: outdoor AC unit with an indoor fan coil; no strip

heater support.

Note that this option allows a HP thermostat to be converted to control an AC

system.

Option 03 - Fahrenheit/Centigrade

Selections:

F = Fahrenheit -- Default is Fahrenheit.

C=Centigrade.

Selects temperature measurement units.

Option 04 - Fan (G) ON with W output

Selections:

OF = G not energized with W -- This is default.

ON = G energized with W.

This selection determines whether the fan (G) is to be ON or OFF when the W

(furnace or strip heat) is ON. Furnaces and fan coils which manage their own

blowers do not require a separate G signal. Some auxiliary heaters require a

separate G signal to operate the blower when W is applied.

Option 07 - Zoning

Selections:

OF = non-zoned system -- This is default.

ON = zoned system.

ON disables thermostat's internal timers which are not needed with zoning

system controls. Must be set to OF for non-zoned systems.

Option 10 -Reversing valve

This selection is only available on heat pump systems. "O" terminal can be

configured to be energized in either heating mode or in cooling mode, depending

on heat pump operation. :'O" is used to describe a heat pump system that

energizes its reversing valve in cooling. :'B" is used to describe a heat pump

system that energizes its reversing valve in heating.

H-- Reversingvalveoutput(O/W2/B)is energizedwhenHEATmodeis

selected.

C-- Reversingvalveoutput(O/W2/B)isenergizedwhenCOOLmodeis

selected.

DefaultisC.

Option11 -Minimum Deadband Between Heating And Cooling

Selections:

01 through 06 -- Default is 02.

Sets the minimum allowable number of degrees between heating and cooling

setpoints. One setpoint will "push" the other to maintain this difference.

Option 12 - Smart Recovery (programmable model only)

Selections:

OF, 30, 60, 90 -- Default is 90.

Smart Recovery OF means setpoints change immediately at a program schedule

change. Thirty, 60, or 90 selects the number of minutes recovery starts before

programmed recovery time. Recovery takes place smoothly during the selected

recovery time, ending at the recovery time and temperature which is

programmed. If the setpoint is changed during smart recovery, the smart

recovery is cancelled and the new setpoint is effective immediately. Not available

with non-programmable thermostats.

Option13 - Room Air Temperature Offset

Selections:

-5 to 5 _' F-- Default is 0.

This option selects the number of degrees F to be added to the displayed

temperature to calibrate or deliberately miscalibrate the measured room

temperature.

Option 15 - Auto Changeover Availability

Selections:

ON -- This is default.

ON allows automatic changeover between heating and cooling as demand

requires. OF maintains either heating or cooling mode only. Auto changeover is

not available when H or C is selected under Option 1.

Option 16 -Maximum Cycles Per Hour

Selections:

2, 4, or 6 -- Default is 4.

The maximum cycle rate is limited by internal timers to the selected number of

cycles per hour. Selection of a higher number causes faster cycling resulting in

more constant room temperature.

Option 17 -Minimum Time Between Equipment Stages

Selections:

10, 15, 20, 25 -- Default is 15.

When there is an auxiliary stage of heat available, this is the amount of time the

heat pump must operate before the aux stage can turn on. With heat pumps,

longertimescanreducetheamountofauxiliaryheatused.Notavailablewith

ACthermostats.

Option18 -Baeldight Configuration

Selections:

ON, OF -- Default is OF.

When ON is selected and the thermostat is not battery operated a low level

continuous display backlight is always on. With OF selected, the backlight is

only on for a short time after the door is opened or a key is pressed. Continuous

backlight is not available with battery operation.

to be disabled when nP is selected. The clock is displayed, but the program

schedule, the HOLD and TEMPORARY HOLD functions are disabled.

Option 25 -Number of Programmable Periods (programmable model only)

Selections:

2, 4 -- Default is 4.

Selecting2 allows2 programmingperiods,P1andP2,perday.Selecting4

allowsperiodsP1,P2, P3,andP4.Notavailablewithnon-programmable

thermostats.

Option26-Minimum Cooling Setpoint

Selections:

52 _' to 90 _' -- Default is 52_'F.

Sets the lowest cooling setpoint available to the user.

Option 27 -Maximum Heating Setpoint

Selections:

50_'F to 88_'F -- Default is 88_'F.

Sets the highest heating setpoint available to the user.

Option 99 -Reset to Factory Defaults

Selection:

See below -- There is no default.

Use this capability to reset the thermostat to "out of the box" conditions.

NOTE: All configuration settings, program settings, clock, and day which have

been manually entered will be lost!

When this option is selected, the configuration number (99), will appear on the

left and 10 will appear on the right. To perform the reset, first use the MODE key

to make the 10 flash. Then press and hold the DOWN key. The 10 will start

counting down toward zero. If the DOWN key is kept pressed until the count

reaches zero, the reset will be performed. If the DOWN key is released early, the

number will return to 10 and the reset will not occur.

Step 4 -- Check Thermostat Operation

The Comfort Series thermostats have abuilt-in installer test capability. Use it to

check thermostat and equipment operation without delays or setpoint

adjustments to force heating or cooling.

To enter the Installer Test mode, use the same process as is used to enter Installer

Configuration, only hold the FAN key longer. More specifically, press and hold

the FAN for about 15 seconds until the display reads In on the left and St on the

right for the programmable model, or InS in the smaller display for the

non-programmable model. The MODE will be OFF. The MODE key (upper

left) can now be used to select heat, cool, or emergency heat, if this is a HP

thermostat. Selecting one of the available modes will immediately command the

equipment to turn on in that mode. It will run for 3 minutes and then return the

mode to off. With HP thermostats (having 2 stages of heating), the test will run

for 3 minutes on each stage. If the thermostat is programmable, the clock display

counts down from 180 seconds while each stage operates. Changing the mode to

OFF will terminate any running test immediately.

During any test, the display icons will be displayed the same as for normal

operation of that stage, as follows:

SELECTED MODE

FEATURES AND ACCESSORIES

Home, Away, Sleep (programmable models only)

This feature provides three button selections which select from three

predetermined pairs of heat and cool setpoints. In programmed versions, one of

these three choices can be selected for any programmed period. To change these

settings, a temperature is first selected and then the key pressed and held, similar

to setting stations on a push-button radio. See Owner's Manual for details.

Clock (programmable models only)

Without batteries the clock will continue to operate for 8 hours while power is

removed. With batteries, the clock operates until the end of the battery life.

Batteries

Battery operation is available for installations where there is no common (C)

wire available at the thermostat or where operation is to continue while the

thermostat is removed from the wall, usually to facilitate remote (armchair)

programming. For battery operation, install two alkaline AA batteries. The

thermostat is designed to operate up to one year on a set of batteries. A battery

indicator on the display warns when battery replacement is needed. See

HomeownersGuidefordetails.If batteriesareinstalledandthethermostatis

operatedfrom24VACpower,batteryoperationwilloccuronlywhen24VAC

powerisnotpresent.Thechangeoverbetween24VACpowerandbatterypower

isautomatic.

Display Lighting

The display has two levels of lighting, high level and low level. High level

lighting comes on for 10 seconds when the door is opened and/or buttons are

being pressed with 24VAC and with batteries. Low level lighting is only

available if the thermostat is operated from 24VAC. It is not available with

batteries. The low level can be selected (see Option 18) for continuous backlight.

Door Switch

When the door is opened, the display changes from its normal operation view.

The large temperature display disappears so it will be available for other user

functions. If the door is left open for 3 minutes, the display reverts to normal

operation.

Mounting Options

For those installations requiring it, mounting hole locations for the

programmable model are spaced to fit either a horizontal or vertical junction box.

Mounting hole locations for the non-programmable are spaced to fit a horizontal

junction box.

OPERATIONAL AND CONNECTION INFORMATION

Rc/Rh Connections

For installations having aseparate 24VAC transformer for heating and cooling,

the R connection can be separated into two connections, one for each

transformer. This allows isolation between the two transformers to be preserved.

To separate Rc from Rh, remove the factory supplied jumper between the Rc and

Rh terminals. The Rh terminal powers the W output. The Rc terminal powers the

Y1, Y/Y2, Gand O outputs.

Wiring

Wire length should be no more than 250 ft. (76m). Use 22 AWG for normal

wiring applications. Continuous wire lengths over 100 ft. (30.5m) should use 20

AWG or larger.

O/B Terminal - On HP Thermostat Only

This terminal is normally connected to the reversing valve of the heat pump. It is

called O when the valve is energized in cooling and B when it is energized in

heating. Option 10 of the Configuration Options makes the O/B selection.

Timers

There are several timers which influence the thermostat's operation:

If any of the timers listed below is preventing the equipment from turning on, the

display icons which show the equipment is operating will be flashing to indicate

a turn-on delay is present.

Five-Minute Compressor Timeguard

This timer prevents the compressor from starting unless it has been off for 5

minutes. It can be defeated for one cycle by simultaneously pressing the FAN

and UP keys.
