If your 15K Btu Advent Air RV Air Conditioner # ACM150 has 120V power but you aren't seeing the 12V power at your thermostat then you'll want to track down that 12V wire and see where the power is being lost. It could be a fuse, damaged wiring, a poor connection, or even a bad ground.

I do not have a 12 volt power source, only 120vac. Is there a way to get this to work?

@Stan @Stan David was using a unit with a wall thermostat, and the wall thermostat requires 12V power. If you don't have 12V power then you need a unit with the ceiling thermostat like the Advent Air RV Air Conditioner System - Manual # ACM150CH so the thermostat is powered by 120V instead.

Hey Matt, we have what you need but the part #ACM150 only comes with the top portion of the system so it would not be correct. You'd instead want the part #ADV32SR if you have a ductless system or the part #ADV92SR if you have a ducted system and…

Hello Berna, so the Dometic thermostat E1 error and the Advent thermostat E5 error basically mean the same thing; that the controller and thermostat are not communicating correctly. Since you are getting this error with both thermostats, that is a…

Answer 3

An E5 error code simply means there's a communication error between the relay box #PXXACRG12RB and the thermostat. If you're hooking it directly to the relay box without any extra wire and it's wired correctly and you're still getting…

Hi Ben, Without knowing the model number to confirm it's hard to say exactly what that E5 error code means. From what I can see it's either a low voltage warning, a communication error between the thermostat and controller, or an issue with…

Answer 5

Advent Air Conditioners like part #ACM135 come with a connector that pairs up directly with the standard 6-wire connector. If you have a 9-wire connector then you need the kit #ACRG15 as well. For wiring I'm attaching some photos of diagrams for…

Answer 6

Typically if there are two wires running from the furnace to the AC system then it means that the furnace has power already connected to it and it sends that through one of the wires up to the AC until the system calls for heat, at which point the…

Answer 7

The start capacitor is not something that is a necessity to use with the Advent Air Replacement RV Air Conditioner #ACCOL135. The AC will run without it, but it is something that is highly recommended, mostly - as you correctly stated - for use with…

Answer 8

For an Advent Air RV Air Conditioner #ACM135 an E5 error typically indicates a communication error between the controller and the thermostat, but it can also indicate an issue with the thermal probe. The thermal probe is typically latched onto the…

Answer 9

Hey Rocky, The A and B wires for the thermostat are just both labeled as "Data Communication". The relay (controller) #PXXACRG12RB for the #ACRG15 would have a blue 22AWG wire for A and purple 22AWG wire for B. If you're reusing the…

Hey there Keith, I am sorry the thermostat on the Air Distribution Box w/ Wall-Mounted Thermostat for Advent Air RV Air Conditioners #ACRG15 is not working correctly. It sounds like a frustrating issue, but let's go through a few things to see if…

Answer 11

Hey John! Yes, the Advent Air RV Air Conditioner System #ADV92SR has everything you need for a complete installation. This comes with the AC unit, thermostat, air distribution box, and a start capacitor. Since this is a new R32 refrigerant unit you…

Answer 12

Hey Eli! The Advent Air RV Air Conditioner System #ADV92SR you ordered is not compatible with a Dometic Duo Therm. However, it really doesn't matter. This is a new R32 refrigerant unit so it won't be backwards compatible with any of the old…
