operate in one of two ways.

de-energize
the MISC1, MISC2,
or MISC3 terminal of the thermostat (this MISC terminal is connected to the
DEHUM terminal on your furnace) to allow the fan to run in low speed when
the humidity in the home is above the dehumidify setpoint you have chosen
and there is a call for 1st stage cooling.
2)
Normally Open
(NO):
The thermostat will
energize
the MISC1, MISC2, or
MISC3 terminal of the thermostat (this MISC terminal is connected to the
DEHUM terminal on your furnace) to allow the fan to run in low speed when
the humidity in the home is above the dehumidify setpoint you have chosen
and there is a call for 1st stage cooling.
