Good morning,
I don't know if I should have opened a new topic, but I hope someone can help me.
The control panel in my building is proel kdc 1803-L. During the renovation, I replaced the intercom based on the old one (according to the seller) a matching digital smart-d 2v2 uniphone. Jumpers for choosing a place should be set well (No. 100). After reading about this, I uniquely took the ZW3 and ZW5, I left the ZW2 and ZW6, and the ZW1 was on the left, I connected the brown-black cable under L + and the yellow-blue cable under L- (you cannot see this test in the photo). The cables were paired by the man who fell while trying to connect, maybe they should not be in such pairs? Maybe you did make a mistake in the store and this intercom does not match, so please give opinions.
