Dehumidification uses a fan stage not currently needed for cooling to
lower the humidity level when the relative humidity reaches the
humidity set point. This feature is activated from the front panel.
The diagram below illustrates how dehumidification works.
If HUMIDITY >= SET POINT:
Case 1:
If TEMPERATURE >= SET POINT + DIFFERENTIAL 1:
The next available ventilation stage is turned on.
Case 2:
If TEMPERATURE < SET POINT + DIFFERENTIAL 1:
Stage 1 fans run continuously.
When the humidity drops below SET POINT: The controller resumes
normal operation.
