The value set in parameter “HU11” identies the reference humidity value, as follows:
- 0 = relative humidity;
- 1 = absolute humidity.
5.4.1 Relative humidity control with proportional control
If parameter “HU11” is set to “0”, humidity control is performed according to the relative humidity value.
Relative humidity is managed according to parameter “HU14”, which identies the probe on which the controller
must guarantee maintenance of the entered setpoint, and on parameter “HU12” that determines the type of humidity
control.
The parameters involved are shown in the table.
The values of the parameters are representative. In specic cases, di󰀨erent values can be set.
