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.
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.
INSTALLATION Installation Notes: d d d The maximum wire size to be used in the installation is 22AWG (0.50mm2) with 0.8mm insulation No part of the control should be installed directly outdoors or in a cabinet outdoors The control assembly base should be mounted before wires are attached Thermostat location: d d d Approximately 5 ft. (1.5m) 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.
d d 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. Compatible Systems Your Carrier Côr thermostat works with most centralized residential heating and cooling systems.

Items Included In Box (Cont.) A14498 Fig. 5 - Installation Instruction, Quick Start Guide, and Wire Labels Items You Will Need A. Phillips screwdriver B. Drill for drilling holes for the mounting anchors with a 3/16” drill bit. 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.
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.
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.
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.

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.
Rc G Y1 W1 (AUX1) O/B A14501 Fig. 8 - Terminal Block Release Lever ! 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.
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.
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.

WIRING DIAGRAMS (Cont.) Accessory Devices The thermostat can control an accessory HVAC device like a humidifier, dehumidifier, or ventilation device from its dry contact ACC terminals (The ACC terminals do not provide 24V AC output). If the accessory is internally powered, connect the 24V to ACC+. Also connect the common for the accessory to common on the control board. 24V ACC+ C ACC- Accessory Device Thermostat Terminals Only needed if your accessory device is self-powered.
