So a few months back I purchased a MRFA-600M-URC-WH dimmer from my local dealer and now I've gotten to finally finishing my room and installing it and it won't learn my MX900's lighting address. Ive followed the instructions and the dummer switch simply will not learn the remotes lighting address. Ive called my dealer but his install guy is on vacation and then has a rather long list of clients to see once he's back. So does anyone else had similar issues with their dimmer switch?
