11 Setting parameters
Temperature Sensor KNX T-AP • Version: 27.01.2020 • Errors excepted. Subject to technical changes.
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 (threshold values, etc.)
are related to the overall reading!
The minimum and maximum readings can be saved and sent to the bus. Use the
"Reset temperature (and/or humidity) min./max. value" objects to reset the values to
the current readings.
The values are not retained after a reset.
6.4. Temperature threshold values
Activate the threshold values that you want to use here. The Temperature Sensor
KNX T-AP provides four threshold values.
6.4.1. Temperature threshold values 1, 2, 3, 4
Threshold value
Set the threshold values directly in the application program using parameters, or de-
fine them via the bus using a communication object.
Threshold value setpoint using parameter:
Set the threshold values and hysteresis directly.
Threshold value setpoint using a communication object:
Beforehand, enter how the threshold value will be received from the bus. Basically, a
new value can be received, or simply a command to increase or decrease.
