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

Presence, Brightness and Temperature Sensor


  • Presence detector with mixed light measurement (daylight and artificial light)
  • Integrated room temperature sensor
  • Glass surface with touch buttons

The Sensor KNX T-L-Pr-UP Touch 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 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 red 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, pure white RAL 9010
  • Brightness measurement Brightness limit value settable by parameter or communication object
  • Presence of persons is detected
  • 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
