Programming duotherm thermostat

Monaco motor home with two dometic roof a/cs. Duotherm thermostat that is new. With Mode on cool, one ac may run on cool and the other on heat pump. Then vice versa. Can someone suggest how to program so both work as they should simultaneously? Very experienced tech in Memphis fixed it a few months ago. Has jumped track again.
  • Thanks to both of you!! I been doing it backwards. Wonder it worked at all.
  • Google:

    Find your thermostat and print a copy

  • Thanks for responding, Chris. It has five buttons. It may well be that I don't know how to set it properly.Mode button is on top. Zone button on bottom. Pressing zone button will change mode. I thought thermostat was messing up. Perhaps all that is wrong is that I need a primer on setting it, if you don't mind.
  • Which Thermostat do you have? They made the multi zone Comfort Control Center in 4 button, 5 button and 10(12) button versions. All of these use separate zones- you must set each zone to do what ever you want it to, they will never operate completely in tandem, as they will have separate temperature sensors. You should be able to set zone 1 to cool, then switch to zone 2 and set it on cool.
