SAFETY CONSIDERATIONS
Read and follow manufacturer instructions carefully. Follow 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 symbol. When you see 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 used to 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
The Carrierr Côrt thermostat is a wall--mounted, low--voltage
thermostat which maintains room temperature by controlling the
operation of a heating and/or air conditioning system, both heat pump
and air conditioner models. Your Côr thermostat has a color touch
screen and interface similar to that used in smart phones. A variety of
features are provided including remote access through web and mobile
apps, separate heating and cooling setpoints, auto changeover, keypad
lockout, backlighting, and built--in installer test. Programing features
allow each day to be independently programmed in half an hour
increments with four preset periods (Home, Away, Sleep, Wake) and
up to six additional custom profile periods. For operational details,
consult the online Owner’s Manual for the specifics at
www.Carrier.com/homecomfort.
INSTALLATION CONSIDERATIONS
Power
This thermostat is powered by 24VAC through the C terminal and thus
most applications require a minimum of 5 thermostat wires. Provision
is made for separate heating and cooling transformers via separable Rc
and Rh terminals which are internally jumpered unless both Rc and Rh
are utilized. Internal jumper is controlled by a relay after the thermostat
senses whether Rc and/or Rh wires are connected to the terminal
block.

Before You Start
Review the all the instructions before you start to ensure that there are
no surprises during installation.

Step 1. Power Off the HVAC System
!
WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in injury or death.
Before installing thermostat, turn off all power to equipment.
There may be more than one power disconnect.
Power off the HVAC system either by a switch at the indoor furnace or
fan coil or at the circuit breaker box.
Verify that the equipment is off by attempting to adjust the temperature
with the existing thermostat. The thermostat may show the temperature
change but your cooling or heating should not come on.
9
Step 2. Remove Existing Thermostat
Remove the cover from your old thermostat. Most snap off easily but
some may be attached by screws.
Note: If the old thermostat has 110/120V wires connected to the
thermostat, it is a high voltage system and is not compatible with this
thermostat.
Look at the wires coming out of the wall. Using the old thermostat
base as a guide, use provided labels to label each wire coming out of
the wall (See Fig. 6).
A14499
Fig. 6 - Label Thermostat Wire
10
Discard any jumper wires between Rh, Rc, or R. This thermostat does
not need them. They are jumpered internally.
When done, remove the old thermostat base by unscrewing it from the
wall. Be careful not to let any wires fall back into the wall.
Discard or recycle old thermostat.
!
CAUTION
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.
Step 3. Attach Backplate to Wall
Position the backplate, ensuring that it is straight by checking the
bubble on the built--in level. Mark the mounting holes on the wall with
a pencil.
11
Installing the optional large backplate
If the small backplate doesn’t cover the marks left by the previous
thermostat, attach the larger backplate instead.
Remove the center piece from the small backplate by gently pushing
the snap and pulling toward you.
Insert the center piece into the large backplate, using the tabs on the
right as a guide. It will snap into place when correctly inserted.
Secure the backplate
Drill mounting holes on the pencil marks with a 3/16” drill bit.
Insert the plastic drywall anchors into the wall.
Use the screws provided to secure the backplate to the wall. (See Fig.
7)

Step 4. Connect the Wiring
The wires from the wall should plug easily into the terminal blocks.
Adjust length and routing of each wire to reach proper terminal and
connector block on mounting base with 1/4--in. (6 mm) of extra wire.
Strip only 1/4 in. of insulation from each wire to prevent adjacent
wires from shorting together when connected. Only one wire can fit
into each terminal block location. Do not try to force two wires into a
terminal block location, it might damage the terminal block or not
fully engage the wires.
When installed correctly, the release lever of the terminal block will
lower to indicate engagement. To release a wire, press down on the
lever. (See Fig. 8)
Match and connect equipment wires to proper terminals of the
connector blocks. If there are separate 24VAC transformers, one in the
indoor unit and one in the outdoor unit, connect the common to the
respective C terminals. Connect the R from the indoor unit to the Rh
terminal. Connect the R from the outdoor unit to the Rc terminal. Then
the W signal is taken from the Rh power and the Y/Y1, Y2, G and O/B
signals are taken from the Rc power.

WARNING
ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in injury or death.
Before installing thermostat, turn off all power to equipment.
There may be more than one power disconnect.
If you need help with the wiring, refer to the wiring diagrams at the
back of this guide.
15
System wiring diagrams covered are:
d Conventional heating and cooling systems
d Heat pumps (air or geothermal)
d Boilers or radiant heat systems
d Accessory devices: dehumidifiers, humidifiers, or ventilators
Attach thermostat
Push any excess wires back into the wall, and connect the thermostat
to the backplate.
Step 5. Power On the HVAC System
Power back on the HVAC equipment. The thermostat will
automatically power on. It is recommended to have the homeowner’s
Wi--Fi password handy in order to complete setup.
Follow the on--screen instructions. The thermostat software will guide
you through the setup, which includes:
d Equipment configuration (HVAC and accessories)
d Setting preferences
d Connecting to Wi--Fi
d Registering the thermostat to the online web portal
NOTE: The settings can be changed at any time from the menus.
Congratulations, you’re done!
16
TROUBLESHOOTING
If your thermostat does not power on, please check the following:
1. Check that all wires are properly inserted into the terminal blocks at
the thermostat. Tug lightly on the wires to ensure they are not loose.
2. Ensure you turned the power back on to the equipment either the
switch at the indoor equipment or the electrical panel (where you originally turned off the equipment).
3. If your device still doesn’t power on check the AC voltage between
Rc and C or Rh and C and ensure it is 24V AC.
