See Fig. 16 for outdoor temperature/indoor humidity relationship in auto
humidify mode.

3. Humidify Off

The humidify function can be turned off completely. This does not re-
quire 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.

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
