I have a 2012 Cedar Creek 36B4. While trying to troubleshoot a problem I reset the Dometic CC2 thermostat. The original problem has been resolved but now the thermostat will only recognize Zone 1. Can't get it to acknowledge that Zone 2 even exists. Has anyone out there run in to this problem? Any ideas would be appreciated.
Thanks

I am having the same problem with my CC2. It was displaying a "E1" code for zone 2. I removed all power and it recognized zone 2. I went away and when I came back, "E1" again and the AC was off. Later, it did the same thing with zone 1. I removed power again and it found zone 1. Still no zone 2. I finally did a reset per the manual and now zone 2 is nowhere to be found on it. Not sure how to even get it to look for it.

The units both run (when recognized), so I think it might be the thermostat. What does anyone else think?

Is there a residential model with multiple zones that can be used to replace the piece of trash Dometic?

Odds are 99 percent it is the OEM INSTALL of the system. There is nothing wrong with the Dometic controls. Usually it is the COMM cables that the OEM make and install. You need to check the COMM cable connections. You do NOT know how and what you are doing but you trash Dometic. I never understand that. NO, there is no other Tstat control system you can use with this type control system. Doug

Apparently, Doug, you have had better luck with cheap RV equipment. These companies make **** (I didn't put stars here either) in the name of keeping things light. The whole RV, and every one I have owned, have been the same from multiple companies. So, thank you for your answer. I am going by a dealer now to talk to them. BTW, I just removed the thermostat off the wall and the plug, that had been glued to the back of it, fell off of it. Not sure if that's my problem or not, but I am starting with a new thermostat. Good day.
