The only thermostat option we offer for the Advent Air RV Air Conditioner # ACM150 is apart of the Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners # ACRG15, which also includes an air distribution box.

The wall mounted thermostat included has a LED display that allows you to control the mode, fan and temperature settings.

I have also included a review video for you to check out as well.

OK I've been going nuts with this and have blown 3 new control boxes. I have the Advent AC 150, It had the Dometic part 3313191.000. So since it's an advent ACM 150, can you tell me which part will actually work with the unit, control box wise, It's a ducted system with a Dometic wall mount thermostat. Any help would be greatly appreciated. Mike

@MikeR Hey Mike. It sounds like your Advent AC unit is an older model that uses the old r410a refrigerant. This would only be compatible with a distribution box and controller made specifically for the r410a Advent units. Sadly, the r410a units are no longer being made so they are unavailable. Unless you can find one secondhand, the best solution here would be to replace your entire AC system so rooftop unit, controller, distribution box and thermostat. This is the only way we can guarantee everything will intercommunicate correctly and work together.

@MikeR Yep they are. Those models are being discontinued though since they use the old r410a refrigerant.
