Good information
one item to note we just replaced both 20 yo old Penguins with new high capacity units for the same noise issue.
in replacing the 5 buttons with the new CCC2 on our 2001 Dynasty it was plug and play for all Zone 1 functions Air, Heat pump, Furnace and Fans with the original cabling.
However even though the CCC2’s are capable of 4 zones each it was not documented anywhere that each zone required its own controller.
our coach has 3 zones for the Aquahot so each Air had a controller but zone 2 for bathroom furnace only in the rear was unrecognized.
Turns out Monaco hid a 3rd 5 button controller in the coach just to control bathroom rear Zone 2 for Furnace. It was undocumented as to location and is different in each unit.
after locating it and replacing it with the “New style CCC2 controller” everything works as before.
(ours was inside a false wall inside the overhead cabinet above the kitchen table against the refrigerator)
5 hours of unanticipated disassembly hunting the location
Dometic Support seemed to not realize the need for the extra controller per zone as all it controls is a “Furnace” Zone for Aquahot
