Adding 3rd air conditioner with One Control question

[Staloch]

1 have a 2021 momentum with the 18 foot garage, im installing a 3rd air conditioner in the garage and my question is can the 3rd air conditioner be run on the one controller? The one controller says bedroom, main and garage for air conditioner settings but my dealer is trying to tell me that only two air conditioners can be run on the one controller. They said i would need to put another thermostat in the garage.

Does it have a temp sensor in the wall in the garage? It will be a small circle grill.

Yes, there is a temp sensor in the garage and it works on the one controller

Then I think the dealer is wrong.

He is claiming that he has been talking to Grand Design

Reach out to GD direct. The temp sensor goes to the One Control system. The wiring for prewiring most likely goes to the One Control, otherwise it would be a control wire on the wall, not a temp sensor.
