If you configure a MISC output jumper for DEHUM, it may be
programmed to operate in one of two ways:
1)
Normally Closed
(NC): The thermostat will de-energize the
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.
Dehumidification Notes:
The DEHUM terminal will “release” and allow
the fan to operate normally if there is call for 2nd stage cooling or if the call
for Cooling and/or Cool to Dehumidify has been satisfied.
