KNX T-L-Pr-UP Touch CH, pure white RAL 9010

Presence, Brightness and Temperature Sensor

The Sensor KNX T-L-Pr-UP Touch CH for the KNX building system detects brightness and the presence of persons in the room and measures the temperature. Via the bus, the indoor sensor can receive an external temperature measurement and processes it together with its own data to generate an overall temperature (mixed value).

The KNX T-L-Pr-UP Touch CH has a settable brightness limit. The limit output and other communication objects can be connected with an AND and OR logic gate. Two integrated touch buttons (bus buttons) and two LEDs can be freely assigned bus commands. The device is supplemented with a frame of the switch series used in the building, and thus fits seamlessly into the interior fittings.


  • KNX T-L-Pr-UP Touch CH white KNX T-L-Pr-UP Touch CH white
  • Brightness measurement Brightness limit value settable by parameter
    or communication object
  • Motion detection
  • Temperature measurements. Mixed value from its own measurement and
    external values (settable by percentage proportion)
  • 2 AND and 2 OR logic gates each with 4 inputs. All switching events as
    well as 8 logic inputs (in the form of communications objects) can be used as
    inputs for the logic gates. The output from each gate can be configured
    optionally as 1-bit or 2 x 8-bit
  • 2 Touch buttons. Bus button, can be configured as switch, toggle, dimmer,
    for controlling the drives, as 8 or 16-bit encoder for scene call up/storage
  • 2 LEDs. Can be configured separately, flash or switch using objects

Configuration is made using the KNX software ETS 5.
