Hi, my GC controller hp18594b has a connection problem. I did buy a new interface card from Dalco Chromtech but as my controller unit is old the new interface card did not fit. I am looking for a newer controller unit but am uncertain about software etc. Anybody knows if it is possible to introduce a newer controller unit without ugrading software for the entire GC?
