Selects a humidity level that the cooling unit will maintain by removing or adding moisture to
the air. The humidity setpoint will either be set in percent RH or as a Dew Point value
depending on what the humidity control type is set for.

Dew Point
Predictive
Selects the humidity control calculation. Setting this parameter to Relative (%RH) will control
the humidity without considering any temperature deviations. Predictive and Absolute
control consider the temperature deviation from temperature setpoint so that a constant
level of moisture is kept in the area based on the humidity sensor reading and the
temperature deviation from setpoint. Compensated is recalculated with the actual deviation
from temperature setpoint. 1 degree Celsius is equal to 3 %RH, indirect proportional. If
temperature increases, the humidity setpoint is decreased and vice versa.

Adjusts the activation points of the humidifier and compressors based on the actual sensor
values deviation from setpoint. The smaller this number, the faster the compressors and
humidifier will increase capacity. Too small of a number may cause the unit to short cycle or
overshoot setpoint.

Integration Time

Adjusts the capacity of the unit based on a time away from setpoint so that accurate
humidity control can be maintained. If the integration time is set to 0, the humidity control
operates as a "proportional only" control. When integration time is set, the control mode
changes to "PI" control

Prevents overshooting of the setpoint and cycling between humidification and

Allows for a target temperature setpoint to be activated when a call for dehumidification is
enabled instead of the traditional method of over cooling the space by increasing cooling to
100% and lowering fan speed if equipped. Must be in supply air control mode. When a call for
dehumidification is active, the supply or remote sensor setpoint will be lowered to this
parameter. This parameter should be set below the accepted dew point threshold of your
space. Used only when supply dehumidification is enabled.

Sets the amount of that the Dehum Temp Setpoint is adjusted once the reheats activate. EX:
If the unit is equipped with a reheat device, this parameter will increase the dehumidification
temperature as the call for reheats are increased until the reheat call is at 100%. When the
reheats are at 100%, the full Dehum Setpoint Adjustment will be applied.
