Before i saw your 2nd post i called an mobile RV tech and he walked me threw a factory hard reset and the E1 code is gone. Its showing one unit instead of two but won't turn on the zone 1 unit. He had me try the heat pump and the fan. They show on for unit one only. I ordered another thermastat as he told me. I will keep you all posted so as if someone else runs into a simular problem.
I can guarantee the tstat is NOT your problem. A reset just verifies the settings on EACH control board. Nothing else. Since the control cable between the 2 zones is defective, that is why the other Zone does not show up. Zone 1 is not communicating with Zone 2. Zone 2 is the control board that is connected to the Tstat. Doug
