2. Description
The KNX eTR 205/206 Light push button has touch-sensitive buttons with which
functions can be called up in the KNX building bus system. The glass surface is printed
with areas for setting the temperature and light. LEDs are integrated in these areas and
their behaviour can be adjusted.
A temperature sensor is integrated into KNX eTR 205/206 Light. An external tem-
perature reading can be received via the bus and processed with its own data to create
a total temperature (mixed value).

temperature can be changed using the "+" and "-" touch buttons.
Communication objects can be linked via AND and OR logic gates.
