The manufacturer of this thermostat cannot be liable for misinstallation, improper connection or improper programming of the humidity functions of this thermostat that may result in water damage or mold growth. Additionally, the manufacturer of this thermostat is not responsible for the fitness of the humidifier and/or installation of said humidifier connected to this thermostat.
Page 44: Dehumidification
Installing the Humidity Module Installing the Humidity Module To install the Humidity Module the thermostat must be detached from the back plate. Plug the Humidity Module into the Humidity Module connector as shown in Figure 2 below. Follow the detailed instructions included with the Humidity Module accessory.

Page 49 Adjusting the Dehumidification Setpoint Dehum Terminal: If a MISC terminal is selected for DEHUM operation (see page 10.2), then the thermostat will provide power to this terminal when the humidity in the building is above the setpoint you have chosen.
Page 50 When the thermostat detects the humidity percentage is above the setpoint for dehumidification, and heating or cooling is not on, the thermostat will force the compressor to run with the fan, thus reducing moisture in the air. The green LED will blink once every eight seconds to indicate this is taking place.
Page 51 Using the Reheat Function Using the Reheat Function This feature allows the thermostat to turn on Electric Heating (W2) during Cool to Dehumidify to maintain room temperature until the dehumidification setpoint is reached. The cooling cycle will allow for the dehumidification of the air to occur while the Electric Heating will allow for a constant room temperature.
Page 52 1st stage cooling and the room humidity is greater than the dehumidification setpoint. 2) Normally Open (NO): The thermostat will energize the DEHUM terminal to allow the fan to run in low speed when there is a call for 1st stage cooling only and the room humidity is greater than the dehumidification setpoint.
