Well my 2011 36RE has the Dometic CC2 thermostat in it. The thermostat went crazy tried everything could not find how to do a system reset.
So ordered a new one happy to say the new one is working now. Only difference between the two the old one had a display for inside and outside temperature. This new one only displays the inside temperature.
New book with the new thermostat says to do a reset when you first install it and it will pickup how many zones you have and it did.
Here is how to do a system reset to a Dometic CC2 thermostat.
1.Turn off the thermostat.
2.Hold down the Zone and Mode buttons it will then display Init.
3. Turn back on the thermostat will now be back to factory settings.
