Comelit 2608

I have a Comelit 2608 and I’m aware that there has also been some discussion around this device in another post. However, I have - with the Nuki not installed - another basic setup as shown in the last picture that appears in that post. Would be great to hear how I could connect the Nuki with this setup. I have added a picture of my basic setup below!
