GENERAL
Carrier’s Comfort Pro programmable thermostats are wallmounted, low-voltage thermostats which maintain room temperature 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, keypad lockout, and backlighting. Programming is available for either 2 or 4 periods per day. The programming interface is a one
touch interface, with the Comfort selections Occupied, Unoccupied, and Limit (Energy Savings Mode). The user can adjust
the heating and/or cooling set points for each of the three comfort selections.
• DONE (6) — Saves settings when completing a set-up
or programming step
• LIMIT (7) — Indicates occupied heating and cooling
settings for the program period which are predefined and
more energy efficient
• UNOCC (8) — Activates heating and cooling settings
for the unoccupied program period
• OCC (9) — Activates heating and cooling settings for
the occupied program period
• D/H/M SET CLOCK (10) — Activates clock set mode

Setting Cooling and Heating Temperatures —
The thermostat is installed with preset cooling and heating
temperature settings. The user can use these settings or change
them. Perform the following procedure to change temperature
settings:
1. Open the thermostat front panel door.
2. Press the up or down button located on the right side of
the display. The preset temperature settings for cooling
and heating are displayed. The word “cool” will flash.

until the heat icon begins to flash.
5. Press the up or down button to change the heat setting.
Stop on the correct setting.
6. For automatic switching from the cooling cycle to the
heating cycle or from heating to cooling, both the cooling
and heating settings must be displayed. If cooling only is
desired, only the cooling set point should be shown. If
heating only is required, only the heating set point should
be shown in the display. To change which modes are displayed, continue to press the mode button until the desired modes of operation are displayed.
7. Press the hold/run button to save these settings.
Using OCC, UNOCC and LIMIT Buttons —
When the user presses the OCC, UNOCC, or LIMIT button,
the preset temperature settings will be viewed and a triangle
icon will appear above the OCC, UNOCC, or LIMIT button
indicating which presets are being used.
The LIMIT button is used for an occupied period with settings that are less conditioned than the Occupied settings but
more conditioned than the unoccupied settings. This is used as
an occupied energy savings function.
The default set points for the Comfort settings OCC, UN-
OCC and LIMIT are listed in Table 1.
Table 1 — OCC, UNOCC, and LIMIT Settings
ONE-TOUCH
SETTING
OCC 68 78
UNOCC 60 85
LIMIT 66 80
The set points for the OCC, UNOCC, and LIMIT OneTouch functions can be modified from their factory defaults using the following procedure:
1. Open the thermostat front panel door. The heat or cool
icon flashes indicating to the user that pressing the up and
down buttons will change the set point value next to the
flashing icon.
2. Change the setpoint of the flashing mode by pressing the
up or down button. The heat or cool icon and the triangle
icon above the OCC, UNOCC, and LIMIT button will
flash.
3. If desired, change the set point of the opposite mode by
pressing the mode button until the opposite mode icon is
flashing. The opposite mode icon and the triangle icon
above the OCC, UNOCC, and LIMIT button flashes.
4. Press the up or down button to change the opposite mode
set point.
5. Then press and hold either OCC, UNOCC, or LIMIT
button for 3 seconds. The triangle icon above the OCC,
UNOCC, or LIMIT button will stop flashing and remain
on. The heat and/or cool set point will flash once when
complete.
NOTE: The thermostats are shipped with fully accessible
keypads. The installer has the option to change the access
to the keypad. This function will not be allowed if keypad
lock 2 or 3 is enabled. This will be allowed if the keypad
lock is disabled or set to 1.

interval or level. Changes within a given programming period
are considered temporary changes that require user confirmation by either closing the door or pressing the done button
which would confirm any changes made up to that point.
If dashes "--:--" appear in the display this is an indication that
the start time in the period displayed is not the same start time
in all periods. Press the start time and update the time for the
HVAC equipment to start.
Temporary Hold Override — The user can temporar-
ily change the temperature from the programmed set points.
Perform the following steps to temporarily override the thermostat:
1. Open the thermostat front panel door.
2. Press the up or down button. This will cause the set point
to be displayed.
3. Press the up or down button again to increment or decrement the displayed set point. This will cause the temporary hold icon to be displayed below the temperature and
replace the clock with the 0:15 minute override time.
4. The temporary hold remains active until a power cycle is
encountered, the override time has expired, off mode is
selected, or the user presses the hold button.
5. To change the override time displayed in the clock location, press the start time button. Each press of the start
time button increments the override time by 15 minutes
up to the maximum value set by the installer.
6. Once the temporary hold is cleared, the override will be
considered inactive and the set point will reflect the program schedule set point.
7. Close the thermostat door.
Holding Temperature Set Points — The user can
override the programmed temperature settings and hold the
temperature at a specific setting. To override the temperatures,
perform the following procedure:
1. Open the thermostat front panel door.
2. Press the hold button (see Fig. 4). This will hold the current comfort setting and the program schedule will be ignored as long as the hold remains active.
3. Pressing the hold button again will return the thermostat
to the current programming schedule.
4. Close the thermostat door.
