Temperature Sensor KNX T-UN
• Version: 27.01.2020 • Technical changes and errors excepted.
The unit can calculate a
mixed value
from its own reading and an external value. Set
the mixed value calculation if desired.
Note:
If an external portion is used, all of the following settings are related to the over-
all reading!
The
minimum and maximum readings
can be saved and sent to the bus . Using the
"Reset temperature min/max. value" objects the values can be reset to the current read-
ings.
Note:
The values are not retained after a reset.

Temperature threshold values
Activate the threshold values that you want to use here. The
Temperature Sensor
KNX T-UN
provides four threshold values for temperature.
5.4.1. Temperature threshold value 1...4
Temperature threshold value
The threshold value can be directly set in the application program using parameters,
or via the bus using a communications object.
Threshold value setpoint using parameter:
Set the threshold values and hysteresis directly.
