This installation guide is for the 4013 light entry signal with distant signal consisting of 7 LEDs by Viessmann for the LED-Classic on the LED bus.

Connecting to the LED-Classic

The wiring diagram shows the pin assignment and wiring of the signal to the LED-CLASSIC.

Since these signals do not indicate which of the green and yellow wires belong to which LED, you should check this beforehand and mark them with a note if necessary.

The pins are assigned as follows:

  • Pin1 Yellow from the main signal
  • Pin2 Green from the main signal
  • Pin3 Red from the main signal
  • Pin VBB is always powered regardless of which of the four it is connected to.
  • Pin4 Upper yellow from the distant signal
  • Pin5 Upper green from the distant signal
  • Pin6 Lower green from the distant signal
  • Pin7 Lower yellow from the distant signal
