New roof airs for an FC, opinions and info wanted

Don't believe the wire colors. You are dealing with two manufacturers and their specs for what color does what are probably different. You need both installation manuals so you can compare the functions of each wire. If you've got a remote thermostat that's probably unique to that manufacturer; if it's controlled from the ceiling panel then you need the new Dometic panel.

Right on the head Stephen... I tell the guys at work, electrons do not know what color the wire is...

The controller is a Dometic as is the new roof unit. In the beginning of this thread it was discussed.

The wiring changes from old to new too.. would definitely double check..
I did away with the proprietary dometic thermostat on my trailer and wired it up like a house unit. Had to add a transformer and 2 relays. I utilized the ribbon cable for the t stat because it would have been too difficult to pull a new one. I was then able to just buy a regular old thermostat and you can get those anywhere..

Custom installations will usually void any warranty. Just a word of possible caution. The new roof units I purchased had a manual that had compatible ceiling units and accessories listed, both mechanical, and t-stat. No problems for me as I purchased all components at the same time.

My unit was an older unit, not new.. so no warranty issues.. from what I have heard about the new units, you may need the warranty more than ever.. so that is probably a good call.. but I consider most of the roof air units as throw away.. its unfortunate, but they are built for manufacturers to maximize profits... I wish a company would start making efficient roof air units, the technology is there for them to be more efficient..just cost..

the new brisk air's I got are surprisingly efficient. and are LG built r-410 units. not bad all around. no reason they cost so much other than "they always have". these roof units should cost about $400 to be in line with good 110v household units. but because of the customer base. they are sold piece meal and total out at $800 minimum for complete new system.

if anyone would simply make a *horizontal* or pancake mount 110v mini split we would all be in business.

Dometic got back to and I ordered a "kit" to wire it in. Hopefully all will be good. Thanks for the responses.

Can you post info and maybe a pic when you get the kit? I did t know they made that stuff. It’s nice to know they are trying...

Also the new air boxes for ceiling mount are relatively awful. So if this lets you keep existing old ones, and save $100. Awesome.

I had already modified the old airbox mount . I had to drill new holes for the 4 mount bolts which of course are smaller. I used 4 1/2" bolts to cinch her up the drain holes are about the only thing that was plug and play..I will post pictures when the kit arrives.
