Setting the parameters
KNX eTR 205/206 Light push button
• Version: 16.12.2020 • Technical changes and errors excepted
A set threshold value will be retained until a new value or a change is transferred. The
current value is saved in so that it is retained in the event of a power supply failure and
will be available again once the power supply is restored.
Set the
hysteresis
independently of the type of threshold value setting.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.

When the following conditions apply, the
output is
(TV = Threshold value)
• TV above = 1 | TV - Hyst. below = 0
• LV above = 0 |LV - hysteresis below = 1
• TV below = 1 |TV + hysteresis above = 0
• TV below = 0 |TV + hysteresis above = 1
Delays can be set via objects
