Viessmann 4013 Color light exit signal

The Viessmann 4013 signals are equipped with LEDs and offer 4 aspects:
Hp00
Hp1
Hp2
Hp0/Sh1



They are robust (metal pole) easily installed and come complete with a diode on the common ground and resistors on all the other leads.

After many hours of work I now have all my signals installed, connected, and working under computer control...
