Dehum Status is a status only item that indicates whether
dehumidification is enabled or disabled.
Rel Humidity is a status only item that indicates the current
relative humidity reading of the sensor .
DewPoint is a status only item that indicates the current
dew point value that is calculated by the controller using the
Rel Humidity= value and either the Space Temp= or Return
Air= value, depending on the setting of the Humidity Sensor
Location . This parameter can either be set to "Space" or
"Return ."
Dehum Method is an adjustable item used to set the
dehumidification method to either "RH" or "DewPt." When
this parameter is set to "RH," dehumidification operation
is controlled to maintain the Rel Humidity= value at the
RH Setpoint= . When this parameter is set to "DewPt,"
dehumidification operation is controlled to maintain the Dew
Point value at the Dewpoint Spt= . When this parameter is
set to "Always" dehumidification will be active as long as
mechanical cooling is not disabled .

RH Setpoint is an adjustable item used to set the relative
humidity value at which the relative humidity will be controlled
to during dehumidification operation.
Dewpoint Spt is an adjustable item used to set the dewpoint
value at which the dewpoint with will be controlled to during
dehumidification operation.
Reheat Spt is a status only item which is used to indicate
the DAT temperature to which the HGRH valve will be
controlled in the Cooling and Fan Only operating states while
dehumidification operation is active. The Reheat Spt= equals
the DAT Cooling Setpoint for DAT controlled units and will vary
in between the Min Reheat Spt= and Max Reheat Spt= for
Zone Controlled units .
Reheat Cap is a status only item that indicates the current
reheat capacity value .
