LU 131 S Combination sensor for brightness and temperature

The KNX combination sensor LU131S KNX
records the brightness and temperature. These values can be transmitted to the bus.

  • Recording brightness and temperature
  • The device has 4 universal channels and 1 sun protection channel
  • The measured variables can be transmitted directly on the bus.
  • Brightness and temperature are each sent as 2 byte values.
  • The data are evaluated in the device itself
  • The universal channels can be used for sub-tasks (e.g. a pure brightness threshold) or for a combination of brightness and temperature.
  • The universal channel allows linking of brightness and temperature
  • Teach-in feature for brightness threshold
