Upgrading CCC to newer model
our coach has the original COmfort control center 5 button model....
I see there is what appears to be a MUCH more user friendly version like this link:
https://www.amazon.com/dp/B00CXB8BY6...&pd_rd_w=IEXAi
Would seem logical that it is possible to update to something that is much more programable and comprehensive.... not sure this one is, but looks fancier anyway...
So what are our upgrade path options? Desired functions would be to be:
Programmable by time of day for all 4 zones, and the ability to auto switch from heat strips to ac on demand for the desired temps....seems pretty basic, but the old 1990's technology CCC leaves a lot to be desired.
I guess I should have posted first, it is a vantare, 2000 XL chassis, with 4 rooftops and aquahot on their own zone old school thermostats...

Ok, So problem located but still need some info...
AC number 4 appeared to be leaking causing come corrosion on the RJ-11 Connectors and Butt Connectors.... PLease see pics....
After some research, it appears the CCC unit ( 4 button) probably ??? puts out some type of serial communication data to the units up top.... they are daisy chained control to 1, then out 1 to 2 etc... all the way down the roof to 4.... the fourth unit has an empty slice butt connector that was all corroded and it appears to have recently shunted the signals from one of the 4 pins to another melting plug.... that in turn then went to the next connector and melted that one as well... but stopped there I guess because it probably melted to an open state or near open state... which is why the number 1 and 2 units appear to work, but the back 2 didn't. it also appears maybe the controller handles these in pairs, and although it can control 4 zones, when I unplug from the first unit back I can still control zone 1/2 and once i started messing with the wires, and moved the3rd connector that had also got hot and melted, my zone 3/4 returned walla... so I dug deeper and yes here are pics of the connectors and the crimp connectors were just as bad..... months ago we thought we smelled some plastic getting hot, but searched and searched for days and couldn't locate it ( there is probably a million miles of low and ac wiring right? lol... Will confirm this once I recrimp new RJ-11 and replace these spices ( pretty sure I still have some, somewhere, the somewhere being the problem)
So here in is my questions... Can someone confirm this shoots some control voltages down that 4 wire phone RJ-11 and also some Serial BUS type of data? not seeing how it could control all the functions just using hi/low voltage logic, and want to confirm... a bonus would be a pinout of the RJ-11 so I can nail down which pins melted, and the results for all to document...
Second question, is it appears ( as I cannot find an output wire on that last connector, that it probably was wired from Vantare as a standard best practice to keep allowing daisy chaining for whatever needs, i.e. maybe a 5th rooftop in some cases? curious as I hate seeing stuff without something connected, and would like to label it as such....
thanks, and finally, can I assume, a 5 button or even a newer controller will plug and and work? before I spend 100+ on the newer 12 button style I'd like to know if it will work or not...
