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.

Dewpoint measurement
The chapter "Dewpoint measurement" only applies to the Mini-Sewi
KNX TH model.
The
Sensors Intra-Sewi KNX T and Intra-Sewi KNX TH
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.
5.9.1. Cooling medium temp. monitoring
A threshold value can be set for the temperature of the coolant, which is based on the
current dewpoint temperature (offset/deviation). The switching output of the coolant
temperature monitoring system can provide a warning prior to any build-up of conden-
sation in the system, and/or activate appropriate countermeasures.
