DEHUM terminal to allow the fan to run in low speed when there
is a call for 1st stage cooling and the room humidity is greater than
the dehumidification setpoint.
2) Normally Open (NO): The thermostat will energize the DEHUM
terminal to allow the fan to run in low speed when there is a call
for 1st stage cooling only and the room humidity is greater than
the dehumidification setpoint.
