To Select Humidification (non-programmable)

Press the features button twice. The first press displays the outdoor air temperature and the second press displays the humidity value and humidify target.

Pressing the mode button shall cycle through the available humidification selections (Off, Humidify and Auto Humidify).

Additional Humidify Comments

The humidifier is actually turned on when humidity is 1% below setpoint and turned off when it reaches 1% above setpoint. This built-in hysteresis prevents humidify output from toggling on and off when humidity level is near setpoint.

Dehumidification

Dehumidification is done only during cooling. Depending on type of equipment used, compressor speed, blower speed, setpoint adjustment, and equipment cycling are modified to provide added dehumidification. A dehumidification setpoint (separate from humidification setpoint) is available to the homeowner. It can range from 46% to 66% relative humidity. When actual humidity is higher than setpoint, a dehumidification demand exists. The Thermidistat Control responds by activating the dry contact (when enabled in Option 19). It may also control the compressor and blower, depending on equipment type and dehumidify selection choice. The 3 available selections are described below. A mandatory 5 minute blower off delay will be enforced if there has been a call for dehumidification during a cooling call. The amount of extra dehumidification available is very dependent on the type of equipment in the home. Without a variable-speed blower, the system’s ability to adjust dehumidification is very limited.
