BBL Posted May 3, 2023 Posted May 3, 2023 I was out checking things in the trailer yesterday and had the AC running. I noticed that airflow favors the curb side of the trailer. If you are looking at the AC from the front of the trailer (you are facing aft) there are two distinct "sides" to the AC unit. You can vary the direction of flow on each side and front/back ratio. When I hold my hand up to the AC, there is clearly more air coming out of the curb side that the street side. Is this a normal occurrence with the TRUMA? I would think it would be much more balanced.

Have you tried adjusting the directional vanes, and the "front vs. rear" slide switch in the bottom middle of the unit? That slide switch can divert air flow either all forward, all aft, or a combination of the two. And, the rotating directional vanes can move air flow side to side. 4 Hull #1291 Central Idaho 2022 Elite II Tow Vehicle: 2019 Tundra Double Cab 4x4, 5.7L with tow package
BBL Posted May 3, 2023 Author Posted May 3, 2023 Yes, front back, side to side. Air is still stronger on one side. Thanks for the tip. BL
Patriot Posted May 3, 2023 Posted May 3, 2023 @Brian and Brandelyne I will be checking air flow in our new Truma after the install next week while at Oliver and will post up if I learn anything helpful.

Does it flow equally on both port and starboard sides? Just want to ensure it is "ops normal" - probably is but want to be sure since I will be stopping by Hohenwald before the rally. Thanks - Brian

BBL Posted June 2, 2023 Author Posted June 2, 2023 They found that a piece of foam had come loose and was partially blocking the air flow and causing the noise I reported. This happened during installation and was not noticed on pre-delivery check. I spoke to Dave, the Truma rep that was at the rally, and he said it is not uncommon for those foam blocks to get dislodged during installation but there is a step to check them prior to installing the interior face plate/panel. It's all good now, have not had any issues since. I just look forward to the day Truma decides to update the CP Plus to include the de-humidification mode. Not very "user friendly" to have to use the remote AND the CP Plus to get it to work. Brian 1 4

BBL Posted June 3, 2023 Author Posted June 3, 2023 @Steve Morris Steve - not that I know of. I told the Truma rep, Dave, at the rally what I had found with respect to using the remote AND the CP Plus and he confirmed, you can only set the de-humidification mode using the remote. I have since put in a ticket with Truma to potentially add this feature to the CP Plus. Some there were surprised to learn you could not do this but they confirmed it, called me back and said they would open a ticket. As I explained to them, we go to the added expense of getting all Truma components and so we could use them from ONE panel and find that all features are not available. I also told them their remote was NOT user friendly, had a poor display and eats batteries for breakfast. They did not disagree with my statements. What I normally do, is set my a/c via the CP Plus then go to the remote, slide down the cover and hit the "Raindrop" button. You have to ensure that you see both the "Snowflake" and the "Raindrop" on the screen. You also have to be pointed directly at the A/C and watch the green light. If you have doubts that it "took" the command, there is a re-transmit button on the remote that will send the setting again (it looks like a wifi signal). Hope this helps! Cheers, Brian 1 3

Cheers, Brian We have found the dehumidify mode works really well! And we also have learned that running our Truma on low it gets colder than a meat locker. We prefer cooler sleeping temps. I don’t see us ever running it in high.🥶 With the (IR function) of the remote it does require it to be directly pointed at the sensor for sure. We learned from the Truma tech at the rally that it’s important to touch the send button on the remote when you touch a different setting. Ahhh the learning curves of the new Truma! The more you learn the better it gets! One thing for sure, it keeps the interior very cool at a very quiet sound decibel. Sleep mode is even quieter if that’s possible.

Great question. I think it just cycles less giving the impression it’s quieter when it’s in this low power mode or sleep mode. Or maybe just not having the Penguin noise banger it’s just so much quieter. A really worthy upgrade for sure.

On our previous 4 trailers with fan (AC or heat) set to auto, it would actually turn off completely when the programmed temperature was reached, a bummer it’s not the same with the truma running all the time, the auto setting is only to switch between heat/cold! 2 2023 Elite II, Hull# 1386, Lithium Platinum Package (640AH, 400W Roof Solar, 3000W Xantrex Inverter), added 400W Renogy Solar suitcase with Victron MPPT 100/30 CC, Truma water heater & AC TV: 2024 Silverado 2500HD 6.6L 10-Speed Allison

Yes, I guess there are trade offs for sure. We are really enjoying the Truma and how quickly it will cool our Ollie down. I ordered a custom made cover for the Truma as I could not find one anywhere on line. It’s due in mid week. I will post up a pic for fitment when it arrives. The design of the rear vents on the Truma are 💯 bird nest condo move in friendly. 😄 Here in Western NC we need to keep it covered when ever we are not traveling.

Ollie-Haus Posted June 5, 2023 Posted June 5, 2023 The thing I notice the most between the low setting and the night mode is the compressor seems to start softer and run at a lower level. The low rumble sound of the compressor is much reduced in the night mode. Honestly once the camper is cooled to a comfortable level, the night mode seems to be very effective at maintaining the temperature and humidity level we like throughout the day. Also based on my experimenting with my generator and running the AC, the Truma on night mode never draws more than 1800 watts on the Gen's onboard meter and seems to have very little serge when the compressor cycles on. I really like these design characteristics. I am a little jealous of the those who have switched from the Dometic unit as I have nothing to compare to.

Regarding the remote controls for both the Truma AC and the Fantastic Fan, I wanted to mount the remote holders in a location that was easy to reach, especially while working in the kitchen, that you can operate while in the wall mount without removing them. This location works perfectly every time and is easily reached while working at the sink/stove.

Do you think there’s any way to fit a screen on the “bird nesting” holes on the Truma? Ah those industrious Carolina Wrens strike again! 😄 Congrats on your new Truma, you’re gonna love it. I gave some thought about screening the holes. The Truma base is molded or formed with a robust tough black styrofoam material likely for weight reduction. Not saying you can’t mod a screen as anything is possible. There are multiple air intakes and it would be an ambitious undertaking to screen all areas in my observation. With the Truma under a 2 year factory warranty I opted not to modify the air intake holes with any mesh screening that could possibly reduce air intake and potentially void the warranty. The custom cover is easy on and easy off.
