I got a Bticino intercom system (non-wireless). I did some restoration in my hallway and disconnected the device. Unfortunately I do not remember how it was wired before I set it up afterwards. Now we got a new common door, so I dunno if it is connected to the intercom system.
I've tried to find a manual of this, but this is an older system and I can't seem to find anything related to it. The wires are differently colored, and ive tried all sorts of connections.
The thing is, I should be able to open the common door for visitors with this unit. And it is also a door-bell (I dunno where the speaker is however) so visitors can ring from outside.
Im not sure where these wires should go, and I also do not know how to be able to open the outer door from this unit. Also on the bottom right of the picture there is a switch.
