This had to be reloaded because it got deleted while adjusting it with my phone. Sorry for the second notification.

Understanding the concept behind a DOAS is important if you are going to fix one, it is its own beast. In Cali we don't see a lot of these. I do have one on a hotel but haven't had to seriously get in to it yet. The day is coming! It's seriously struggling. Dont worry about it It's working!" LOL

There are plenty of guys on YouTube that specialize in residential HVAC. We don't need more of it. We need content in comercial / lite-comercial.

An example, I like the fact that HVACTIME now specializes in chillers. Do I miss his content on VRF? Yes but I understand It gives those chiller guys somewhere to turn to.

Very nice unit. And that Frenchie is beautiful. I want one

Nice unit. I work on a 100% OA with 30 k cfm it took the Contrators 1.5 yrs to get the setup right for extreme cold. I had to use them for warranty purposes. I still have to tweak it from time to time. Niagara N4 automation. Beautiful dog. One more thing. That EZ condensate trap is great for indoor use, but will dry rot in the sun.

That is a Greenheck RV Unit. The RVE has an energy recovery wheel in the unit has well. The school district that I work for has been having several of these units installed during building renovations. They are used as 100% DOAS units in conjunction with the VRF systems. I have some videos of them on my channel as well. Consider me a new subscriber!

It’s amazing how a little set up can screw up the operation. I have some Valiant units very similar to those units. Once you get them dialed in they’re pretty much worry free. You figure out more when the season cycles. Good video.
