Operation: Control the Environment
Dehumidify. Dehumidify mode is controlled by the dehumidify PID controller. The PID controller adjusts the output as required to maintain the temperature at the setpoint.
See “PID controls” on page 23 for a description of the PID controls and instructions on tuning the dehumidify PID loop.
Humidify. The steam cylinder humidifier output is controlled by the humidify proportional controller. When the control humidity drops below the humidify setpoint, the humidifier output increases as the control humidity drops until the output reaches 100%.
See “Humidification sensitivity” on page 25 for a description of the Humidification sensitivity band.
Setpoints
Path: Main > Control Environment > Setpoints
Setpoints are the target values that each mode maintains in the room. The default setpoints are appropriate for most precision cooling applications.
The setpoint for each mode must be within the following ranges:
•Cool: 61.8–90.0°F (16.5 to 32.2°C)
•Reheat:
•Dehumidify:
•Humidify:
If a mode is disabled and you change the setpoint, the display warns you that the mode is disabled. See “Modes” on page 22 to enable or disable operating modes.
You cannot overlap setpoints. If you attempt to overlap setpoints, the display warns you and resets the setpoints.
Note The Cool setpoint must be 1.8° F (1° C) above the Reheat setpoint, if reheat is installed in the Module. The Dehum setpoint must be 1% Relative Humidity above the Humidify setpoint, if a humidifier is installed.
