When we opened up our camper for the first time, our Zone 2 unit wasn't working, initially there was an error code E1. We have a Dometic thermostat 50-070701-g is the number. Zone 2 isn't even showing up when I press Mode and Zone, only Zone 1. We have tested and there's power to the air conditioner unit. We replaced the circuit board in Zone 1 and Zone 2, nothing changed and it still wouldn't run. We set the Dip switches the same as the originals. We ran a phone line from the working unit to the non working unit and the Zone 2 unit kicked on, but still didn't show up on the thermostat. Any suggestions on how to get it to register?
