Nuki Opener - move from 3 wires intercom to the futur

Hello everyone :wave:

I’m new here.
I hope I am in the good place to talk, don’t hesitate to redirect me to the correct area.
I need help.

I’ve just bought a Nuki opener and can’t wait to see it in action, but so far, it brought me a huge headache. (Please excuse my English if what I write is sometimes confusing, I’m French).

Once I bought the opener, I’ve realized that the version of the intercom I had was not in the list (bitronvideo AV1407/002). So I bought a Urmet 1133/15.

The issue I have is that the previous intercom works with 3 wires, and the instructions are for a 2 or 5 wires configuration.

I’ve tried to connect the wires in a lot of positions, but I can’t find how to make it work properly.

Does anyone knows how to move from a 3 wires to a 2 wires ? Or is there a solution to make the opener work with my previous intercom ?

I’ve spent hours and hours on the internet trying to understand something, and I came across this website.

Please don’t hesitate to share your opinion.

Hello, i have the same problem, with this bitron video.
Do you found an issue ?

Not yet.
