RV Comfort. ZC thermostat.
Mine is showing 00 in temp window. Won't change to zones 1 or 2 or operate AC or Furnaces. Tried shutting power down to reset, worked once but not working again. Does it need to be replaced? Any idea...

All motor homes with that system have that problem and the manufacturer can only guess what the problem is. To eliminate the 00 remove the face and remove the fuse for 3 minutes and put back in. Generally the only time there is a problem is on generator power on the heat cycle. If you leave your electric hot water heater on it solved the problem for us. (No one could explain why)
