Step 2 — POWER OFF YOUR HEATING AND
COOLING SYSTEM
1. Turn off the power to your heating and cooling system.
S You can do this either at your circuit breaker box or a
switch at your indoor furnace or fan coil.
S Most systems have one switch but some systems have
two switches.
2. Make sure your system is without power by using your old
thermostat to adjust the temperature. Your system should
not turn on.
5. Remove your old thermostat base by unscrewing it from the
wall.

Option 01 - Equipment type
You may need to make an adjustment to this setting depending on
the system you’ve connected. If you’re unsure about your system
type, refer to wiring diagrams beginning on page 5.
Options: Air Conditioner (AC), Heat Pump (HP), PH, or PC
Description:
1. AC or PC controls 1 speed air conditioner with one stage of
heat.
2. HP or PH controls 1 speed heat pump with 1 stage of auxiliary heat.
3. PH or PC selects PTAC units (Packaged T erminal Air Conditioners) which are used in motel rooms and other rented
spaces. When this option is selected, the display shows only
the setpoint, not the room temperature. Also, the compressor timeguard is disabled, allowing the compressor to turn
on immediately when a demand is established.
Option 03 - Fahrenheit/Centigrade
Default: Fahrenheit (F)
Selections: Fahrenheit (F), Centigrade (C)
Description: This selection operates the thermostat in either
Fahrenheit or Centigrade.
Option 04 - G (fan) ON with W (Heat) Selection
Default: G not energized with W (OF)
Options: G not energized with W (OF), G energized with W (ON)
Description: This selection determines whether the fan (G) is to be
ON or OFF when 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 10 - Reversing valve
Default: Reversing valve energized in cooling (C)
Options: Reversing valve energized in cooling (C), Reversing
valve energized in heating (H)
Description: Applies only when configured for Heat Pump
applications. Most systems use the orange (O) wire and are
energized in cooling.
S Select Energized in Cooling (C) if you connected an (O) wire in
the O/B terminal to activate the reversing valve output when
there is a call for cooling.
S Select Energized in Heating (H) if you connected a (B) wire in
the O/B terminal to activate the reversing valve output when
there is a call for heating.
S If you are unsure, consult your heating and cooling system
equipment installation instructions or contact Carrier customer
support.
Option 13 - Room Air Temperature Offset
Default: 0°F
Options: +/- 5°For+/- 3°C.
Description: The number of degrees to be added to the displayed
temperature to calibrate the measured room temperature. The
selected number is the number of degrees, plus or minus, which
will be added to actual temperature. This option is in °Fevenif
Option03issetfor°C.
Option 15 - Auto Changeover
Default: Off (OF)
Options: On (ON), Off (OF)
Description: This feature allows the thermostat to automatically
change between heating and cooling mode when a demand has
been present in the opposite mode for a period of 20 minutes.
Manually changing either the cooling or the heating setpoint will
allow an auto changeover to occur without the 20 minute time
constraint. The heat setpoint and cool setpoint are separated by a
minimum of 2°F.
Option 21 - Keypad Lockout
Default: Off (OF)
Options: On (ON), Off (OF)
Description: With ON selected the keypad will be locked and can
be unlocked by simultaneously pressing the UP and DOWN keys
