Does the Thermostat in the Advent Air Distribution Box Turn On an Off When It Reaches a Temperature?

Updated 10/08/2025 | Published 10/07/2025

Question:

When you say, built in thermostatinch I assume its not an actual thermostat that turns off and on by reading the inside temperature? Basically its manually turned off or on, correct?

No, the Air Distribution Box w/ Built-In Thermostat item # ADV48SR turns on and off when it reaches a certain temperature inside the trailer. This one is exclusively for Advent ductless systems with R32 refrigerant.

What AC Unit are you looking to install the item # ADV48SR on? This system has the new R32 refrigerant in it and is not compatible with any AC built before 2025 that doesn't have the new R32 refrigerant, including Advent ones.

You can add this information and any other questions you have where it says Reply to Jerred H and I'll be happy to answer them.

Ok, Jerred, here's my situation: I bought a Dometic Brisk 2 from Camping World 3 months ago for my little 20ft travel trailer. It cost a lot. Now it no longer produces cold air and CW refuses to honor the warranty. Therefore I'm strapped for money to replace it but found an Advent 15,000btu with etrailer that is reasonable but, I've the old Dometic ceiling distributor that looks just like this Advent one we're discussing. I believe mine will work but it does not have an actual thermostat. However, if the Advent one does and can be set at a temperature that will automatically turn the a/c on and off, I'd be willing to purchase it? Darrin

@Darrin Yikes! That sounds like a complete mess. Not sure how old the camper is but have you tried contacting Dometic directly? If they can't warranty it they may have some troubleshooting steps they can run you through. The Advent Air Distribution Box item # ADV48SR only works with the Advent systems that came out in 2025 with the R32 refrigerant. It does not look much different than the older ones that worked with the 410a refrigerant so you'll definitely want to pay attention to that detail when looking at buying AC systems separately. The 15,000 Btu Advent Air RV Air Conditioner System item # ADV32SR would replace your entire Dometic Brisk 2 system. It comes with a 15,000 btu AC unit, the air distribution box we were discussing, a start capacitor, and a 2-year warranty.
