6.12. Humidity PI control
The chapter "Humidity PI control" only applies to the TH-L-Pr model.
If you activate humidity control, you can use the following settings to define control ty-
pe, setpoint values, and humidification and dehumidification.
General control
The sensor can be used to control one- or two-level dehumidification or combined hu-
midification/dehumidification.
Configure a block for the humidity control using the blocking object.
Specify when the current control variables are to be sent to the bus. Periodic sending
is safer, in case a message does not reach a recipient. You may also set up periodic
monitoring using an actuator with this setting.
The status object shows the current status of the output variable (0 = OFF,
>0 = ON) and can for example be used for visualisation.
Controller setpoint
Set, in which cases
setpoint values
received via object are to be retained. Please note
that the setting "After power supply restoration and programming" should not be used
