I have a strange problem with my Bticino intercom and I hope you can help me or point out where the error might be.
Whatever I do with the wiring, the intercom will not turn on, unless the Bus- coming from the wall is directly put into Bus- of the intercom.
Normally, I am supposed to attach it to the yellow opener cable inside the clamp that’s delivered.
Every other cable is then either put into bus+ or bus- of the intercom. But whatever I try, the intercom will not turn on.
It will just turn on, if bus- coming from the wall is put into bus- of the intercom directly. It will also work as normal once that’s done. I also can use the opener features with other cables connected, but of course doorbell suppression is not working.
Strangest thing: It worked before.
Additional info: Opener has been exchanged, so I am trying it with a brand new opener, which is running on 1.2.7.
The previous Opener ran on beta 1.4.2, I believe. Whatever is the current latest release.
Thanks for any help.
