Depending on the model number of your thermostat the humidification options are: View the ambient humidity at the thermostat location Control a humidifier with the HUM terminal on the thermostat Dehumidify using only the air conditioner Dehumidify with Reheat using your HVAC’s second stage electric strip heater Dehumidify using the DEHUM terminal on yourfurnace’s circuit board Page 1 Installation Installation The humidity accessory is inserted into thehumidity plug on the back of the thermostatand the Humidity Jumper is set for HUMoperation.

Humidity Module circuit board. Page 2 Humidity Operation Humidity Operation To control a MISC output for humidification, place the MISC1, MISC2, or MISC3 jumper on the term- inal labeled HUM. This will supply 24VAC to the selected MISC terminal on the backplate of the thermostat when the humidity in the home falls below the setpoint you have chosen. The value for this setpoint ranges from 0% to 60%. Only one of the three outputs (MISC1, MISC2, or MISC3) is required to have this jumper. For more information regarding the MISC1, MISC2, and MISC3 outputs and regarding the Humidity setpoint, please consult your Owner’s Manual. The Fan may also be programmed to automatically energize any time there is a call for humidity. For more information regarding energizing the Fan with Humidification operation, please consult your thermostat’s Owner’s Manual. Page 3 Dehumidifying With The DEHUM Terminal* Dehumidifying With The DEHUM Terminal* Dehum Terminal: To control a MISC output for dehumidification, place the MISC1, MISC2, or MISC3 jumper on the terminal labeled DEHUM. This will supply 24VAC to the selected MISC terminal when the humidity in the home is above the setpoint you have chosen. Only one of the three outputs (MISC1, MISC2, or MISC3) is required to have a jumper. For more information regarding the MISC1, MISC2, and MISC3 outputs, please consult your thermostat Owner’s Manual. When the indoor humidity falls below the setpoint you have selected, the MISC terminal will be de- energized. The value for this setpoint ranges from 25% to 99%. To utilize this feature your HVAC unit must be equipped with a DEHUM terminal. For more information regarding dehumidification using the DEHUM terminal, please consult your thermostat’s Owner’s Manual. *Dehumidifying with the DEHUM terminal may not be available with your thermostat model number. Please consult your Owner’s Manual for details. Page 4 Dehumidifying With Air Conditioning* Dehumidifying With Air Conditioning* Cool to Dehumidify: If Cool to Dehumidify is onand the Humidity Module is installed, the thermo- stat has the ability to initiate a cooling cycle for advanced dehumidification operation. When the thermostat detects the humidity percentage is above the setpoint for dehumidification, and heatingor cooling is not on, the thermostat will force the compressor to run with the fan, thus reducingmoisture in the air. The green LED will blink onceevery eight seconds to indicate this is taking place. This feature will also allow you to adjust the coolingovershoot of the setpoint, from 0 to 5 . ° ° For Example: If the cooling overshoot is set for 3 F and ° the cooling setpoint is set for 74 F, then as long as the ° room temperature reads between 71 F and 74 F this °° feature will energize the compressor and fan to dehumidify the air. When the indoor humidity falls below the setpoint you have selected, the Cool to Dehumidify functionwill be de-energized. The value for this setpointranges from 25% to 99%. For more information regarding dehumidification using the air conditioner, please consult your Owner’s Manual. *Cool to Dehumidify may not be available with your thermostat model number.
