Sensors Intra-Sewi KNX TH-L-Pr and Intra-Sewi KNX L-Pr
• Version: 30.08.2018 • Technical changes and errors excepted.
The
minimum and maximum readings
can be saved and sent to the bus. Use the
"Reset humidity min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.
5.11. Humidity threshold values
The chapter "Humidity threshold values" only applies to the TH-L-Pr
model.
Activate the required air humidity threshold values. The menus for setting the th-
reshold values are displayed.
5.11.1. Threshold value 1, 2, 3, 4
Threshold value
Set, in which cases
threshold values and delay times
received via objects are to be
retained. The parameter is only taken into consideration if the setting via object is ac-
tivated below. Please note that the setting "After power supply restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the first communication (setting via objects is ignored).
Set the threshold value directly in the application program using parameters, or define
them via the bus using a communication object.
