    Does anybody have 3rd air conditioner connected to One Control?

    Im pitting a third air conditioner on my Momentum in the garage. My one controler has thermostat control for bedroom, main, and garage. The RV place that i bought the RV from said the talked to Grand Design and you can’t connect the garage to the one control. It has to be on its own thermostat. I find that hard to believe beings it has garage on the one controller already

    I added a a holding tank to my momentum, and was able to hook it up to the one control. So I think it is possible.Doing the wiring after it is built, may be a problem though. That could easily be the real issue.

    Yes. 3rd factory unit is on One Control. Only reason you wouldn't be able to add to one control would be wiring from control board to A/C nonexistent. If there's a wire pre-wired, should be doable. If not, you'll have to run wire, again doable depending on how much effort you're willing to go through or pay for.

    My 2021 395MS came with only 2 ACs. Dealer installer 3rd and it was pre-wired for one control.
