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...

Replacing the tstat will not fix the problem. It is transient AC ripple thru the RV electrical system causing your problem. Lights or other 12 volt appliances are causing the problem. How long did you wait when the 00 code displayed? On some ZC tstats, waiting 5 to 10 minutes will auto reset from 00 to the correct display. Transferring 120 power from Shore and genset or switching 12 volt power disconnect on and off will sometimes cause the 00 display and waiting 5 to 10 minutes lets it auto reset. Pulling the Tstat fuse for 5 minutes is quicker. Doug
