Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners - White

The installation of this, replacing all my original Dometic parts and wiring, is fairly straightforward, although you won't get much help from the instructions as they are written for 1st time installs. When you get to your furnace wiring, you get just one wire from the Advent thermostat, where my Dometic unit had 2 (+/- 12v). After much research and reading a few blog posts, I learned that taping off the positive 12v lead (stuff it out of the way) and connecting the negative lead to the Advent thermostat wire allowed the Suburban furnace to cycle properly. The real frustration with this is that the plastic vent cover for the distribution box assembly is too big for the opening thereby blocking air flow through the louvers, should you choose to use them (they are flush against the ceiling). Of the 6 factory pre-drilled screw holes, 4 line up with the Advent factory assembly, 2 do not. The fix for this is to just put screws into my RV fiberboard ceiling. That is a poor workaround. I believe this poor fit is a design mistake although the Advent folks believe otherwise. If you buy this packaged kit, be prepared to have to field engineer it or use your original plastic vent (in my case Dometic) if you are using the standard 14x14 opening. I give the etrailer folks high marks for trying to help, however, they only sell it. Advent imports it. I include photos to better explain this.1544767

Going with 3.5 stars, rounding up to 4. Seems very odd that the rear two mount holes do NOT go into the frame, but rather into the ceiling of the coach. Distro box itself is soft plastic and really directs a huge amount of air along the roof and rear, not much for being able to adjust down or around.

Going from analog thermostat with 6 wires to this digital thermostat and controller with 4 wires did have me run new leads from the unit down to my furnace. Having 3 fan speeds and the smaller thermostat controller is nice. I ran the 12vdc+, 12vdc-, furnace lines down to the same lines at my furnace, pictures included may help explain. From the control box, red (box) to red (lead) to red (furnace) and blue (coach) 12VDC+...Black (box) to Black (lead) to Yellow (furnace) and White (coach) 12VDC-...Brown (box) to Yellow (lead) to Blue (furnace) thermocouple control, previously the white wire at the analog thermostat.

Otherwise, seems to do all the things that it should, looks nice and is easy to operate. This unit replaced the coleman mach unit of unknown age in my 1993 Tioga Class C1673759

I reached out to Advent and they would like to speak with you directly. I will provide them with your contact details.

These people are awesome! The air distribution box came, but would not function (we had a certified RV tech installing it). We contacted etrailer.com customer support and they sent us a return shipping label and a new air distribution box (which worked great). If I need anything etrailer.com carries, you can be sure I'll buy from them again.1321797

Excellent! No problems at all.

The unit itself works great. We have to remove the cover when closing our slides. The cover is beautiful bigger than the original.1683360

Great customer service, communication, super fast shipping ordered on Tuesday and received on Thursday. Both items arrived at same time, 4 days before expected delivery date.
Will continue shopping with etrailer.com. 5 stars AAA++++++1677710

It has been a good unit. It is still kicking out cold air. It would be even better if it wasn't as noisy but I have yet to see any rv acts that are. The price was the main reason I went with this unit along with free shipping, couldn't be beat. Also the customer service was top notch. Thanks1630504

Ordered this to replace the 13.5 air conditioner I had this one has been great so far no issues definitely would recommend1608298

Excellent service and fast delivery. The only reason for 4 stars instead of 5 is the unit is not 100% compatible with some Dometic units.
If you are replacing a unit that has a Dometic 3313379 control or similar with 2 furnace wires labeled y3 and y4 this will require a additional relay.
The advent system has 1 wire labeled 12 volt dc-Furnace.
The Y3 and Y4 on the Dometic are 12v dc and ground. If you put a jumper on them even with nothing else hooked up, the furnace will start.
Buy a 12 volt dc relay (either 4 or 5 terminal) at your local auto parts store for about $10.
Hook the Advent wire labeled 12 volt dc-Furnace to one side of the relay coil, and the other side of the coil to negative dc.
Hook the Y3 and Y4 wires to the normally opened terminals on the relay.
Mount the relay, and you are done. When you select furnace on the thermostat it closes the relay you added and after the normal delay (about 30 seconds), the furnace will start.
If you are familiar with wiring you shouldn't have a problem.
Hope this helps someone with a similar system.1531619

The product quality as excellent. Installation went easy considering I knew what I was doin. If I had to rely on the directions if would have for sure been more difficult.1629331

Product works well but the instructions were abysmal. I bought this part right before Covid-19 stopped us all in our tracks so it sat around for a very long time before I got a chance to install it. I purchased it to upgrade by Advent AC which only had knobs to control it and no thermostat. I really don't understand how anyone would want an AC without a thermostat but that's how the AC came. First I had to run a thermostat wire -- looking at the part online I determined that I needed 4 wires for the thermostat so I bought that in advance on [resell store] for a few dollars. I drilled a hole where I wanted to mount the thermostat and fished the wire all the way to the existing AC. I removed the existing grill and "dumb" control module and then reassembled the new parts pretty much the same as they came off. I turned on the breaker and pressed the on button on the thermostat but nothing. Thinking that I did something wrong I dug out my multimeter to check for voltage at the thermostat but nothing. Back to the directions and after looking over the circuit detail I figured out that this smart control needed 12V DC to run. So I fished a 12v DC lead and connected it to the control -- now everything worked -- well almost. In putting on the cover I discovered that it would not fit because unlike the "dumb" unit which had the control board hanging down, this one needed it up. So I cut off all of the wires, turn it over and wired everthing back up. Turned the breaker on at voila, everything works and the cover fit too! One more note, the ACRG15 is for non-ducted use but the cover sent which clearly said ACRG15 on the box had the vents covered with a piece of metal and some sticky foil tape -- taking it off wasn't an issue but the manual included was also for an ACRG12 (don't know if they even make one for this one).1115294

Thank you for your detailed review. The ACRG12 is on the manual because it installs the same as the ACRG15.

Working as it should!

Odelia was Great. she was very helpful in assisting me with what I needed She directed me to the Advent site who also helpful.
She was the first person at e trailer that gave me her direct line which I was able to call back and get the right parts that I needed.1561565

Product delivered in a timely manner and as advertised1684997

Works good needed to contact ASA for wiring of 12 volt supply1687858

Great customer service!! Very fast delivery. Will continue to shop with etrailer1576678

Install was straightforward and pretty easy. The unit runs good but we haven’t had a chance to use it in hot weather yet1622378

Have installed box and thermostat. This was wired into an older dometic system that was a hardwired setup. As a work around due to no plug to plug the new advent ac to. Rather spendy but worked well. Unit is up and running and all works well. This allows all functions of the ac1079686

Operating very well.well satisfied with purchase.

Great service. Thank you 1673616

The connection where the thermostat wires connect to the thermostat is weak and broke. I was able to solder the connection. Otherwise would be 5 Stars1553374

You didn't explain the air-conditioned on line when I order it if I knew it was a heat pump I would have never order it1489174

Exactly how described 1671199

The product itself is good! The customer service is horrible! I have a five person list of people that were suppose to return my call immediately. Not one of them reform my call and it's been a full week.

(1) First of all it was going to take months to get the 15k ac I wanted. I had to downgrade to a 13.5k in order to get out this year.
(2) Second
The rep told me I didn't need the control panel. She said I could use my old one. After I installed it, it worked for a few days fine. It just dropped blowing after those few days. I spent a week trying to figure out if I needed to order that box or something else. I left multiple messages with the first woman I spoke with. No response. I stayed over with 3 additional sales people with the same result. Nobody knew what to do. Nobody called me back. They sent me to the manufacturer. The manufacturer was zero help also. He told me to call the person that sold it to me. I did this circle jerk for about a week. Finally I spoke with someone with half a brain who told me I needed to buy the distribution box. He looked it up and shipped it out after I paid extra to "move to the front of the line"! No apologies no discount on the product. He did give m e a small refund on part of the shipping. He emailed me the product that HE CHOSE to send me. WRONG PRODUCT! I told him I needed it to fit a ducted system. He sent me the one for nonducted!
3 (Three)
I called back...of course the same person was not available. Kind of lucky I guess because I finally spoke to someone whom I believe carries the load of a full brain. I think it was Paul that finally sent me the correct product (twice the price of the first)

4 (four)
I again had to pay extra for priority so I didn't have to wait a week.
Keep in mind that etrailer is only 30 minutes from my doorbut they do not have a will call.
Anyway...I paid extra to get it the next day. Next day comes....no part!

My overall experience? My overall experience is that it was horrible! I will try my damndest to never order from etrailer again!!!1337133

This unit is perfect replacement part. Easy to install.1557310
