1SAFETY CONSIDERATIONSRead and follow manufacturer instructions carefully. Follow all localelectrical codes during installation. All wiring must conform to localand national electrical codes. Improper wiring or installation maydamage thermostat. Recognize safety information. This is thesafety----alert symbol. When you see this symbol on the equipment andin the instruction manual, be alert to the potential for personal injury.Understand the signal words DANGER,WARNING,andCAUTION. These words are used with the safety----alert symbol.DANGER identifies the most serious hazards which will result insevere personal injury or death. WARNING signifies a hazard whichcould result in personal injury or death. CAUTION is used to identifyunsafe practices which may result in minor personal injury or productand property damage. NOTE is used to highlight suggestions whichwill result in enhanced installation, reliability, or operation.
2INTRODUCTIONThe CarrierrCôrtthermostat is a wall--mounted, low--voltagethermostat which maintains room temperature by controlling theoperation of a heating and/or air conditioning system, both heat pumpand air conditioner models. Your Côr thermostat has a color touchscreen and interface similar to that used in smart phones. A variety offeatures are provided including remote access through web and mobileapps, separate heating and cooling setpoints, auto changeover, keypadlockout, backlighting, and built--in installer test. Programing featuresallow each day to be independently programmed in half an hourincrements with four preset periods (Home, Away, Sleep, Wake) andup to six additional custom profile periods. For operational details,consult the online Owner’s Manual for the specifics atwww.Carrier.com/homecomfort.INSTALLATION CONSIDERATIONSPowerThis thermostat is powered by 24VAC through the C terminal and thusmost applications require a minimum of 5 thermostat wires. Provisionis made for separate heating and cooling transformers via separable Rcand Rh terminals which are internally jumpered unless both Rc and Rhare utilized. Internal jumper is controlled by a relay after the thermostatsenses whether Rc and/or Rh wires are connected to the terminalblock.
3INSTALLATIONInstallation Notes:dThe maximum wire size to be used in the installation is22AWG (0.50mm2) with 0.8mm insulationdNo part of the control should be installed directly outdoors orin a cabinet outdoorsdThe control assembly base should be mounted before wires areattachedThermostat location:dApproximately 5 ft. (1.5m) from floor.dClose to or in a frequently used room, preferably on an insidepartitioning wall.dOn a section of wall without pipes or duct work.Thermostat should NOT be mounted:dClose to a window, on an outside wall, or next to a door lead-ing to the outside.dExposed to direct light or heat from the sun, a lamp, fireplace,or near other temperature--radiating objects which could causea false reading.
4dClose to or in direct airflow from supply registers and return--air registers.dIn areas with poor air circulation, such as behind a door or inan alcove.Compatible SystemsYour Carrier Côr thermostat works with most centralized residentialheating and cooling systems.Heating: up to 2 stagesCooling: up to 2 stagesHeat pumps: 1 or 2 stages + 1 or 2 stages auxiliary heat (Intelligentheat staging capable)Gas, oil, electricHybrid HeatrDual Fuel systemsGeothermal systemsAccessories: Humidifier, dehumidifier, or ventilator

8Items Included In Box (Cont.) A14498Fig. 5 -- Installation Instruction, Quick Start Guide, and Wire LabelsItems You Will NeedA. Phillips screwdriverB. Drill for drilling holes for the mounting anchors with a 3/16”drill bit.Before You StartReview the all the instructions before you start to ensure that there areno surprises during installation.
9Step 1. Power Off the HVAC SystemELECTRICAL OPERATION HAZARDFailure 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.!WARNINGPower off the HVAC system either by a switch at the indoor furnace orfan coil or at the circuit breaker box.Verify that the equipment is off by attempting to adjust the temperaturewith the existing thermostat. The thermostat may show the temperaturechange but your cooling or heating should not come on.
10Step 2. Remove Existing ThermostatRemove the cover from your old thermostat. Most snap off easily butsome may be attached by screws.Note: If the old thermostat has 110/120V wires connected to thethermostat, it is a high voltage system and is not compatible with thisthermostat.Look at the wires coming out of the wall. Using the old thermostatbase as a guide, use provided labels to label each wire coming out ofthewall(SeeFig.6).A14499Fig. 6 -- Label Thermostat Wire
11Discard any jumper wires between Rh, Rc, or R. This thermostat doesnot need them. They are jumpered internally.When done, remove the old thermostat base by unscrewing it from thewall. Be careful not to let any wires fall back into the wall.Discard or recycle old thermostat.ENVIRONMENTAL HAZARDFailure to follow this caution may result in environmentaldamage.Mercury is a hazardous waste. Federal regulations require thatmercury be disposed of properly.CAUTION!Step 3. Attach Backplate to WallPosition the backplate, ensuring that it is straight by checking thebubble on the built--in level. Mark the mounting holes on the wall witha pencil.
12Installing the optional large backplateIf the small backplate doesn’t cover the marks left by the previousthermostat, attach the larger backplate instead.Remove the center piece from the small backplate by gently pushingthe snap and pulling toward you.Insert the center piece into the large backplate, using the tabs on theright as a guide. It will snap into place when correctly inserted.Secure the backplateDrill 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)

14Step 4. Connect the WiringThe wires from the wall should plug easily into the terminal blocks.Adjust length and routing of each wire to reach proper terminal andconnector 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 adjacentwires from shorting together when connected. Only one wire can fitinto each terminal block location. Do not try to force two wires into aterminal block location, it might damage the terminal block or notfully engage the wires.When installed correctly, the release lever of the terminal block willlower to indicate engagement. To release a wire, press down on thelever. (See Fig. 8)Match and connect equipment wires to proper terminals of theconnector blocks. If there are separate 24VAC transformers, one in theindoor unit and one in the outdoor unit, connect the common to therespective C terminals. Connect the R from the indoor unit to the Rhterminal. Connect the R from the outdoor unit to the Rc terminal. Thenthe W signal is taken from the Rh power and the Y/Y1, Y2, G and O/Bsignals are taken from the Rc power.

16System wiring diagrams covered are:dConventional heating and cooling systemsdHeat pumps (air or geothermal)dBoilers or radiant heat systemsdAccessory devices: dehumidifiers, humidifiers, or ventilatorsAttach thermostatPush any excess wires back into the wall, and connect the thermostatto the backplate.Step 5. Power On the HVAC SystemPower back on the HVAC equipment. The thermostat willautomatically power on. It is recommended to have the homeowner’sWi--Fi password handy in order to complete setup.Follow the on--screen instructions. The thermostat software will guideyou through the setup, which includes:dEquipment configuration (HVAC and accessories)dSetting preferencesdConnectingtoWi--FidRegistering the thermostat to the online web portalNOTE: The settings can be changed at any time from the menus.Congratulations, you’re done!
17TROUBLESHOOTINGIf your thermostat does not power on, please check the following:1. Check that all wires are properly inserted into the terminal blocks atthe thermostat. Tug lightly on the wires to ensure they are not loose.2. Ensure you turned the power back on to the equipment either theswitch at the indoor equipment or the electrical panel (where you orig-inally turned off the equipment).3. If your device still doesn’t power on check the AC voltage betweenRc and C or Rh and C and ensure it is 24V AC.FEATURESThe Carrier Côr thermostat has a touch screen and interface similar tothat used in smart phones.Accessing your web portalRegister the Carrier Côr thermostat at www.Carrier.com/myhome tocontrol it from your smartphone, tablet or desktop, and to access freeonline energy management tools.Downloading the appControl the thermostat from your smart phone.
