18 Setting the parameters
KNX eTR 205/206 Light push button • Version: 16.12.2020 • Technical changes and errors excepted
The minimum and maximum readings can be saved and sent to the bus. Use the
"Reset temperature min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.
9.4. Temperature threshold values
Activate the required temperature threshold values. The menus for the further setting
of the threshold values are then displayed.
9.4.1. Threshold value 1, 2
Threshold value
Decide in which cases threshold values and delay times received are to be kept per
object. The parameter is only taken into consideration if the setting by object is activat-
ed further down. Please note that the setting "After power restoration and program-
ming" should not be used for the initial start-up, as the factory settings are always used
until the first call (setting via objects is ignored).
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.
During initial commissioning, a threshold value must be defined which will be valid un-
til the first call with a new threshold value. For units which have already been taken into
service, the last communicated threshold value can be used. Basically, a temperature
range is given in which the threshold value can be changed (object value limit).
