Hello everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at the replacement digital relay box for the Advent Air RV air distribution boxes. Now, this part here will replace the digital relay box that's on your Advent Air RV air distribution box. This one is designed to fit the part number ACRG15. That part number we do sell separate on our website.
Now, you can see there's a bunch of wires that come out of this box, and we're just gonna go through these wires. So, you can see there's four wires right here that are all taped together. And you can see marked, it says thermostat only. And then each individual wire is labeled to help you for your connection. These will connect to the thermostat.
There where we do have this gray wire, this large gray wire here and it has two plug-in connectors on the end, and it is marked heat pump only. And then we have this single black wire that has a plug-in connector on it, and it is labeled connect to the free sensor. Now, the free sensor is not included. That we do sell separately on our website. And then the three remaining wires you can see, there's a brown, a red and a black wire.
Basically, the black wire is the ground. The red is the power. And the brown is marked to the furnace. And that's what all the wires are marked and labeled for easy connection. But that should do it for the review on this replacement digital relay box for the Advent Air RV air distribution boxes..
Perfect replacement for my 2012 Advent Air RV Air conditioner. They moved the location of the 120 volt power entering the unit but I was able to make it work. All other wiring was exactly the same. Shipping was two days later than originally scheduled.
Great product it was an exact match to what I wanted. Thank you so much!
Works perfectly.
Old box stopped working, bought replacement now AC is back on. Great service had it delivered next day. It's hot in Orlando.
I installed it powered it up I’m getting nothing out of it!

Thanks for reaching out on this, I know that’s frustrating when you get everything installed and then nothing happens. A couple quick things to check, this relay box needs a solid 12V power and ground, and it also has to be paired with a compatible Advent Air distribution box and control setup. If any of those connections aren’t lined up just right, it can act like it’s completely dead. If you can, double check your power and ground at the unit, and make sure all the plugs are fully seated. If everything looks good there, it would really help to know what exact Advent Air system you’re running or even see a quick photo of the wiring. We’ll help you get this figured out
