Setting the parameters
Room Temperature Controller KNX eTR 101-BA2
• Version: 20.04.2021 • Technical changes and errors excepted.
Enter the hysteresis that prevents frequent on/off switching of temperatures within the
threshold range.
If separate actuating variables are used, the choose if the actuating variable of the 2nd
stage is a 1-bit object (on/off) or an 8-bit object (on with percentage/off).
Now specify what should be sent when the control is blocked.
On release, the control variable follows the rule again.
In the case of a common control variable for heating and cooling, 0 is always transmit-
ted as a fixed value.
7.5. Temperature threshold values
Activate the required temperature threshold values. The menus for the further setting
of the threshold values are then displayed.
The threshold value always refers to the associated measured value that is received via
the "Temp. threshold value X: measured value" object.
7.5.1. 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.
