RV Comfort Z.C

Rear ac can be controlled, but pushing the toggle to move to front ac results in no response. Unit has been working fine. Reset the breaker no luck. Suggestions welcomed.

Thanks Doug, it worked.

The Tstat is 12 volt controlled. Take the cover off the tstat and remove the fuse for 10 minutes. Reinstall and see if you can toggle between zones. If not, check the front Zone 1 control board on the AC unit. Doug
