I don't have an auto transfer switch on mine, but I don't think it will work without 12v going to it. Maybe your batteries are completely dead? Maybe use jumper cables from your TV to get enough juice to get it to work? I'm sure other will jump in who are more knowledgeable on this. Good luck!

I love your math and will be using it as my sales pitch for new Nev-R-Lube axles to my wife. She'll then return the favor by letting me know what she'll be spending that saved money on!

I find it works fairly well if you keep the phone close to the internal antenna mounted in the cabin. Usually adds 2, sometimes 3 bars for us. .

Oh, I have no doubt it will work with my Turbro, I just don't think it will have the ability to override functions programed into the control board of the unit itself.

In a perfect world, it would work just as you describe. With the Turbro/Pioneer inverter units, at least, this doesn't seem to be the case. Yes, the compressor does ramp up and down as needed but the internal supply fan works no differently than standard compressor units do. The fan has low/med/hi settings and is not a variable speed ECM motor like residential mini-splits have. Probably a money saving move and feature they thought people wouldn't miss in an RV. I sure miss it... especially in heat mode where the fan locks on high speed and doesn't allow any adjustment. Looking forward to testing with a Cielo thermostat soon to see if it can override this feature but my hopes are not high...

They also replaced the plywood subfloor with a composite, which is a big plus.

Section 551.71(F) of the NEC is specific to RV parks only so not applicable to your situation. And as @Snackchaser stated, wiring to only one side of a double breaker is fine per the NEC. Might not be needed though if your local AHJ hasn't adopted the new code yet.

I thought I read something a while back that the new code requires GFCI protection in a residential setting but RV parks were exempt. Don't have a new code book but will see what I can find. Edit: looks like the updated NEC 2023 code 210.8(A) does include any 125 through 250 volt outlets installed in a garage or accessory building be GFCI protected. The code covering RV parks was not updated so only pedestal outlets 20 amp and under are still required to be GFCI protected. Contact your local construction services dept to see if they've even adopted the new code or not, and if they have, I would just install a 30 amp single pole GFCI breaker for that outlet.

Right now my built-in sensor is reading about 5 degrees off in cooling and 10+ in heating. Hopefully the Cielo will be able to work around this for me.

This brings me to another question on the Cielo. How does it control setpoints... does it override the thermistor reading, or does it just keep adjusting the AC unit temp setting to match what the Cielo is reading if the temps between the two don't align?

Ah.. Then should work with just about all of them with a remote. Thanks!

I have high confidence that the Ceilo will work to control these units, the big question is will it override the built-in fan control that keeps the fan running when the compressor shuts down?

I could be wrong, but I think most of the noise is due to the small area inside the plenum and lack of any decent sound deadening insulation inside it. Definitely not coming from the outside portion of the unit which is whisper quiet. I do like your idea of letting some airflow bleed off around the top with spacers and may try that first before increasing the plenum size. In the end, it's not horribly loud but I know it could be better...

Have they actually ever performed this mod at RecPro for anyone before? Still wondering if the Cielo thermostat could shut down the fan with the compressor on this unit like it does on the Atmos. They'd probably sell a lot more of the Houghton's if you could skip the mods and just add a thermostat to it.

No, the Turbro unit is identical to the Pioneer. And while much quieter than the Dometic, it's not as quiet as the Atmos and some others. On the plus side, it runs on about half the watts or less than standard compressor models and it's a heat pump too.

Got a chance to test the heat pump function last night and was pretty impressed with it's performance. Operating in the high 20's / low 30's it was able to keep the inside heated to 70 degrees. Built-in temp sensor reading was off even further than in cooling mode so thinking I might have it installed in the incorrect location to read temps right. That shouldn't matter soon since I'll be installing the Cielo Max thermostat which I hope will override the temp sensor.

What were your issues, and how did you resolve them?

Looks perfect!

Recall on the 3.5 V6 twin turbo has been expanded to another 127k vehicles. If you own one, it's probably a good idea to go to Toyota's recall page to see if yours is affected. 127,000 Toyota, Lexus Vehicles Recalled for Engine Debris Toyota Recall lookup

Gary- it's likely that the support arms got bent or damaged when the wind got a hold of it. You'll probably have to have someone pulling out hard on the awning while someone else cranks it to get it open to see what the damage is.

More than a few people have had issues with the ground and neutral connections inside the EMS itself. That's the first place I'd check.

This is exactly what I'm thinking about doing- adding an inch spacer in between the two inside covers to increase the plenum area. I have a sheet of thin white PVC that I can cut 1" strips from which will be easy to mold into shape to go around the outside edge between the two. I'll also have to do the same with the inner return air opening to keep the return and supply air from mixing. Will add better sound deadening foam too. I didn't measure the height off the ceiling, but I'm sure there's plenty of room to bring it down another inch, at least for 6' tall me....

I only had about an hour or so to play with it so I could have being doing something incorrectly in the settings. Looking forward to spending more time with it, especially once I get the Cielo thermostat installed. And, If the Cielo is able to override the internal temp sensor, that will be worth its cost alone.

Yeah, seems as though little thought went into designing a proper plenum to distribute the airflow and reduce sound. Aesthetics over function? It's amazing that it's as quiet as it is... If enough of us complain, maybe they'll redesign a new inside cover?

I think they might have been more concerned with the size of the cover than managing noise level. Might want to take a close look at how the ducting is ran before installing. I didn't have the time to do so myself but will when I return on Thanksgiving.
