DEHUMIDIFICATION - This option is ONLY available to
modern circuit boards with DEHUM inputs.
On these circuit boards DEHUM is connected to R
to allow high speed fan and disconnected to force low
speed fan. The Intellistat signal Y2 connected to DEHUM
will keep the fan in high speed unless there is a 1st stage
cooling demand, the humidity control is ON,
AND
the
room humidity is ABOVE the humidity setpoint. In any
other condition (humidity demand, mode off, or heat)
DEHUM will be forced active to enable the highest fan
speed.
