Hello,
I am trying to get an Urmet 1750/1 running. It is a 2 Voice Video System. There are two wires called “Line” and two wires “CP”. CP are probably not relevant as these seem to be “Chiamata al piano” (Call to the floor/Etagenanruf) according to a few Urmet wiring instructions.
I am trying to connect Nuki Opener to this Urmet but constantly fail. Please see the picture attached.
The 1750/1 could be similiar to the 1183-5 if this helps. The latter seems to be the voice-only version.
Thank you for your help or any ideas on how to tackle this.
Best regards
Max
