I have a control4 system with an older card access Heavy duty power controller ZCA-HPC10A that they no longer sell. I have 3 of these in my system and removed one of them to relocate to a new area and having alot of trouble reidentifiying to my controller C4-EA1. I've used the proper leave mesh sequence, and now, when reidentifying the unit, it fails to establish a connection. The other units were added almost 10 years ago and have always been part of the mesh since the older HC-1000 days, Any suggesrtions on gettin the unit to rejoin the mesh or a replacemnt for the unit?
