2.Auto Humidify
Thermidistat Control will automatically adjust the humidity setpoint according to the outdoor temperature. As the outdoor temperature decreases, the humidity setpoint also decreases. Settings ranging from 1 to 9, 1 being the lowest and 9 the highest, will be visible to the homeowner. See Fig. 17 for outdoor temperature/indoor humidity relationship in auto humidify mode.
3.Humidify Off
The humidify function can be turned off completely. This does not require changing existing setpoints.
To Select Humidification (programmable)
Press the soft key below the humidify icon to bring up humidity select screen. Humidify options are only available when in Heating mode. When system is in AUTO mode, humidify options are available if the last system operation was a call for heat.
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.
