For dual-level dehumidification, the setpoint value difference between the two levels
must be defined, i.e. the setpoint value which, when exceeded, triggers the switch to
the 2nd level.
Determine the deviation from the setpoint value at which the maximum variable value
is reached, i.e. the point at which maximum output is used.
The reset time shows how quickly the controller responds to deviations from the set-
point value. In case of a short reset time, the control responds with a fast increase of
the control variable. In case of a long reset time, the control responds somewhat less
urgently and needs longer until the necessary control variable for the setpoint value
deviation is reached.
You should set the time appropriate for the humidification/dehumidification system at
this point (note manufacturer instructions).
Now specify, what should be sent when the control is blocked.
On release, the control variable follows the rule again.
6.13. Dewpoint measurement
The chapter "Dewpoint measurement" only applies to the TH-L-Pr
model.
The sensor calculates the dewpoint temperature and can output the value to the bus.
Activate the monitoring of the coolant temperature if required. The menus for setting
the monitoring are displayed.
