Bill I think you may have less confusion/better answers if you start a new post and mention that you are looking to add a thermostat to a non-ducted a/c unit. From the comments I think some are thinking you want to change out an existing thermostat.

I think one challenge will be getting the wire for a t'stat over to the wall.

Any personal thoughts/experience on the Penguin II versus the Brisk II? I’m reading the Penguin may actually be somewhat louder inside, but what a/c unit isn’t (non-ducted). Any noise level that’s lower is a bonus for her.

The design of the Penguin makes it inherently louder than the Brisk-aire. The reason is the size of the airbox. The Penguin, because it's a smaller unit, has a smaller airbox. That causes the input (warm) air and the discharge (cooled) air to flow through the airbox at a faster velocity. Fast rushing air is "louder" than "just rushing air" which is louder than "slow air"... Think of a 20" box fan. Turn it on low, it moves a little air and is relatively quiet. Turn it on high and it moves more air. Stand in front of it and you can hear the air and the fan blades "rushing through the air". The faster the blades and the air move, the louder the fan "discharged air". It's the same with the Penguin vs the Brisk-Aire. This is a case where, even in an RV where size is a factor, bigger is better....

I’ve looked at the thermostat wire scenario and believe it’s doable over into a into a cabinet area. You’re correct, a new post would put more eyes on the subject. I’m also considering a different roof unit and if that becomes the case (possible warranty issue at hand currently, waiting on answers), then a thermostat ~might~ be possible for us.

Thanks John, Danny and Marshal. Enjoy the knowledge you all have here. (The Penguin noise is understandable). We’ll stay the course with the Brisk.

I can empathize with your wife. I've had 7 cervical spine surgeries myself. Not only is looking up problematic for me so is reaching overhead. Hope you find what you need to make the conversion or replacement.

If you are looking for "less" noise - whatever that is with an RV AC. The Brisk Air II is a bit more quiet. We had a 15k Brisk Air and had a Penguin II added before we took possession of the last trailer. The Brisk Air was ducted and the Penguin was not and in the bedroom The Penguin was louder due to a few factors so if going that route keep that in mind. For us the Penguin was fine because we like "noise" when sleeping; heck, at the s&b we have 3 (yes THREE) fans around our bed just humming away year round. For the past few decades I have been a very light sleeper and the slightest noise wakes me like a shot. 3 fans = lots of "white noise". Puppy and the alarm system can/will alert me if needed.

Good luck on getting the right unit w/thermostat. Keep in mind that the Dometic CT thermostat appears to still be problematic. It's already acting up in this trailer and folks with new units on another forum are reporting the same issues.....

Danny,
I came across this while on the search for the micro-air a/c soft start unit earlier this morning. I thought of you and your problems with the Dometic thermostat. This may or may not be an option for you and others. (or maybe this is a BTDT moment?)

Thanks Bill! That thermostat looks very interesting. I'm thinking I'll give one a whirl when I get back to give it a try. When I've been able to put it through its paces I'll report back.

I am resurrecting this thread for an update. The Micro Air thermostat has received a lot of conversation since it came out earlier this year (best recollection). As one of thousands of folks that has had non stop trouble with the Dometic CT thermostat, replacing them over and over plus carrying a spare at all time.....all I can say is WOW!

I'm on several forums and these things have been installed by others and to the person of all I'm aware of they are very happy - count me in.

Got mine some time ago but haven't had my trailer (in for repairs). Got the trailer back several days ago and the first thing I did was install the Micro Air. Easy install...very easy. Works like a charm. What you don't realize is that it operates more intelligently that the Dometic thermostats ie; run full power, go to low fan, high fan, compressor on/off...shut off....turn on - a never ending cycle. The Micro Air? Turn it on and you just don't know the AC is running. Yes, you hear it in the background but all that kick in, kick down, turn off, turn on is gone - lovely!

Anyway, I bought one to replace the stat for the main unit but I will now replace the one for the back AC - far too many positives not to. Now....I've updated as I said I would.

Excellent news, Danny! Thanks for sharing and updating this. You would think that Dometic would take note and redesign. Meanwhile... Micro Air does its thing and sounds like it does it right. I know the Micro Air A/C Easy Start module I installed works very well.

Yes Bill, you would think that Dometic would take note and redesign...by now. This has been going on since they starting using the CT thermostat. Now, 7-8+ years later, the CT thermostat is still defective, and Dometic is more than aware of it. On this 2020 we started having the same old "what the heck is going on with the AC/furnace"? Sent Dometic an email about the new unit malfunctioning and the response? "We're aware of the issue and will be addressing it". ?? They did say they would send a new unit...as they do repeatedly to anyone with one. It's silly IMO.

If it was mine with that capacitive touch thermostat it would be gone and replaced with the unit from Micro Air...

That’s exactly what he already did.

I have to agree. From everything I've read and those I've talked to that have installed one, they are all as pleased as I am. It's hard to believe it can change the operation so much - I just thought that's the way RV ACs operated (I've never owned a Coleman Mach). Apparently the thermostat can drive your stuff a little batty. I've not used it on the heat pump or furnace because it's been too warm but I expect to see the same benefits. Another positive IMO is the ability to set a temp and the stat will keep it there whether it has to heat or cool; wifi; bluetooth - pretty cool. Wish I had done it years ago.

I've seen other threads where folks are having problems with the soft touch Dometic thermostats having a mind of their own.

I saw this in a different forum. Maybe it's a solution. So far reports are very good.

My 2020 Passport 2600 came with the Dometic Capacitive touch control... until I was advised by this forum, on what the settings needed to be at (specifically blower on Auto) I had the AC blower and furnace blower both on at the same time...and didn't know why and General RV was of zero assistance..
My only complaint now is that it isn't even close to accurate temperature wise.. if you set this thing to 68 it will cook you out of the trailer...you dial it down to 62 and it shuts down but then it seems that you have to bump it back up to turn it back on to heat back up... so it's really an unreliable thermostat... Also isn't reliable on AC either.... doesn't hold a temp there either...

Is this Micro Aire unit a plug and play type of replacement for the Dometic one I have in my passport?
