Hi i can not connect opener to Urmet intercom 1132/620 there are only 2 wires can you help
Hi! Try this, red&orange opener wires on “+” together with the wire what is already there, and black opener wire to “-” also together with the wire what is already there, now reset the opener to factory settings, and do a fresh setup (without ring suppression for now, if it works, we can search for this function later), and choose generic bus, on setup!
