Configuring the system Configuring the system 1 On the thermostat, not a mobile device, swipe the HOME screen twice to the left to navigate to the MODE screen and ensure the MODE is OFF. NOTE The yellow line above a button indicates it is the current MODE. 2 Swipe to go to the FAN screen and then press and hold the Fan Button SYSTEM SETTINGS screen. for 5 seconds to get to the NOTE You can ONLY access the SYSTEM SETTINGS screens from the thermostat itself, not the app or web.
Configuring the system To configure advanced SYSTEM SETTINGS You can only adjust the following the SYSTEM SETTINGS screens and parameters on the thermostat itself. You cannot access them on a mobile device. You can select FACTORY DEFAULTS to restore all default settings to the original values. Parameter Name/Description Default and Range HEAT EQUIP TYPE — The equipment heating type.
Configuring the system Parameter Name/Description Default and Range SMART RECOVERY — Transitions the conditioned space from one programmable temperature period to the next with 1°F increments of the heating setpoint or with 1°F decrements of the cooling setpoint, so that by the time the next period starts, the setpoints are at the desired temperature. The purpose of the gradual transition is to use less energy by preventing staging up (because of a higher demand) to higher stages.
Configuring the system Parameter Name/Description Default and Range REMOTE SENSOR — Determines whether the remote sensor hardware input is: D: NONE • NONE — Not used R: • NONE or SPACE — The outdoor temperature is acquired by Wi-Fi through the server, based on the location of the mobile device used to connect the thermostat to a router, or based on the ISP location, if a computer connects the thermostat to a router.
Configuring the system Parameter Name/Description Default and Range CYCLE TIMER — The maximum number of heat cycles per hour. D: 4 R: 2, 4, 6, 8 HUMIDIFIER — The 6th output relay that enables a field-installed humidifier. The humidifier is on if there is humidity demand and any heating equipment is on. If set to YES, the thermostat cannot be configured as the 3rd stage compressor, Humidi-MiZer™, Dehumidification, or HP reversing valve operation.
Configuring the system Default and Range Parameter Name/Description HP LOCKOUT — If you select OFF, the heating equipment cycle always starts with the heat D: pump, regardless of the outdoor air temperature. R: • If you select a lockout temperature and the outdoor air temperature is less than the selected temperature, the heating cycle is started with the AUX HEAT source.
Configuring the system Parameter Name/Description Default and Range OCCUPANCY OUTPUT — When set to ON-(*) or ON-W2, selected relay output equals current Occupancy state. Can be used for ECON Enable. D: OFF R: OFF ON-(*) ON-W2 OCCUPANCY INPUT — This setting changes the current heating and cooling setpoints to the option selected for MAX HOLD TIME. This occurs when the short is detected on the Remote Space Sensor for the duration of 2 to 5 seconds.
Operating your system using the Carrier® Connect™ Wi-Fi Thermostat Operating your system using the Carrier® Connect™ Wi-Fi Thermostat The thermostat supports the following types of constant volume units: • Standard heat/cool unit types with up to 3 stages of mechanical cooling, up to 2 stages of gas or electric heating, and up to 4 stages for non-Carrier heat pumps • Heat pump units utilizing a reversing valve output for heating and cooling control • Carrier heat pump unit with an OEM defrost control
Operating your system using the Carrier® Connect™ Wi-Fi Thermostat Cooling The thermostat's application and configuration determine the specific cooling sequence. It can control up to 2 stages of cooling, with an additional output for a reversing valve, for non-Carrier heat pump applications, or up to 3 stages of cooling for non-heat pump applications. NOTE The cooling stages are controlled based on a drift algorithm and the configurable DIFFERENTIAL value (.
Operating your system using the Carrier® Connect™ Wi-Fi Thermostat The following conditions must true for heating to operate: • The OAT must be below the HEAT LOCKOUT (55°F default), if enabled • The heating stage 5-minute minimum off-timer has expired • The space temperature has exceeded the heating setpoint by the DIFFERENTIAL value (.
Operating your system using the Carrier® Connect™ Wi-Fi Thermostat Humidification There is occupied and unoccupied humidification on units that are equipped with humidifiers.

Using the Carrier® Connect™ Wi-Fi Thermostat's screens HUMIDITY To adjust the thermostat's humidify and dehumidify setpoints: • Drag the wheel up or down • Tap the top of the wheel to decrease the setpoint by 1% • Tap the bottom to increase the setpoint by 1%. If cooling equipment is not available, COOL TO DEHUMIDIFY is not adjustable on the thermostat and the blue Dehum Setpoint wheel is not adjustable.
Using the Carrier® Connect™ Wi-Fi Thermostat's screens Humidi-MiZer™ When the output is configured as a HUMIDIMIZER output, and the humidity level is above the dehumidify target, 24V is output at the terminal. When the humidity level is below the dehumidify target, 0 Vac is output on the terminal. There is a +1/-4% hysteresis around the dehumidify target to prevent rapid on/off cycling of the output. This output may be connected to compressor outputs on commercial equipment.
Using the Carrier® Connect™ Wi-Fi Thermostat's screens PROGRAM You can only view the program schedule on this screen on the thermostat. You cannot adjust the schedule or setpoints. Permanent program schedule changes require the Connect App. Making temporary changes or pausing the program schedule are outlined in Using the Connect App (page 13).
