Opener on Urmet 1132-D005C

I’m trying to install the Nuki Opener on the Urmet 1132-D005C intercom.

I found the model “1132” in the app but not this specific variation.

I have only two wires coming from the wall connected to the unit. There is a port which connects the circuit board to the headset. There are no other ports from which one can remove wires.

The app instructions mention to remove the “port CA” – I can’t see this anywhere.

Can anyone help with this model?

With this intercom, one must ring the bell and the handset much be lifted before the door can be opened.

I tried both of the following options but none appear to work. I get the messages “The installation of your intercom system does not comply with the standard”

Option A)
Putting cable (+) into the clamp
Putting red and yellow cables into the clamp
Putting green and orange cable in the (+) position

Option B)
Putting cable (0) into the clamp
Putting red and yellow cables into the clamp
Putting green and orange cable in the (0) position

Hello
Has anyone managed to install the Nuki Opener with the Urmet 1132-D005C, is it working?

Thank you
