Newly installed Duotherm AC not working in Zone 2

Just had a brand new rear AC installed but the controller is not recognizing that there is a Zone 2 for that AC in our coach. Anyone know what might be the problem? Seems that the person that installed the AC is now handing the issue over to Dometic saying AC is no good. Thanks.

The 2 A/C units must have compatible electronics and be connected to one another in order to function propely! I suspect that the PC Boards are not identical and the Newest one may not be designed to work with the Comfort Control Center in Your coach.

I wonder if the Telco type connectors are plugged into the correct sockets?

Did the installer set the Dip Switches correctly on the control circuit board inside the rooftop A/C unit? They have to be different for the front versus the rear.

Are the data cables inserted correctly and tight with good clean contacts?

There is a zone controller for each a/c, with the dip switches that Dr4film mentioned. It may be a separate box with some thermostats, or may be built into the a/c unit. Get that wired and configured right and it will work.

If you have the Comfort Control Center thermostat, do you have a 4 button or 5 button? The new units use a 5 button and will not work on the 4 button thermostat. You will have to change the control board on the other unit as well as the thermostat and set the dip switches. Once set then reset the thermostat and you should be good to go.
