So I'm here with Donald and we're here at Norman s, right in Oakland, California, Donald and Norman s, Wright were kind enough to host me here and I wanted to have Donald give me just a look through this training center cuz. It's actually really cool. It's nothing. Like I've ever seen on the PRV side, I almost said the RF on the vrv side.

Cuz, it is old. I can I'm gon na turn the camera around and we're just gon na kind of walk through what they have in here and let Donald explain what they got going on all right. So a lot of that first time, I'm just gon na give you a quick view of the room here, and this is a really nice training center, I'm very thankful that they are allowing me to kind of storm their grounds, first being an on vrv expert. Let's start over here and just kind of walk the way through the equipment and the controls and what you have here and just kind of introduce everything we kind of specialize in in-house technical sport and the patrol side.

Really because that's that's kind of where the industry struggles, what we see out here is controls integration and how it works. So we offer to all the control vendors that we deal with anybody that wants to bring your equipment here. Let's let's test it right. So we have all of our live equipment that that is functional, that you would see exactly in the field how its set up.

We even get the error codes right. We test the product to make sure that when we get on a job site that it that it works right - and we have the answer for that random question - that you get at the end of the job - so that's really why this place is here is right. We have all live working equipment so that we can troubleshoot with the tech we offer two different training classes free to all of our clients. We have our regular install class, which is just gives you the inner the overview of how the system is installed and how it should operate.

And then the next class would be our service and troubleshooting class, which kind of gives them a deeper dive into the operations of the units. So Norman s right is a distributor, rep firm for multiple different products. So I mean you can see our lovely skylights up here. Greenheck damper so obviously gripped Greenheck and we are the solar sugar for Dyke in vrv in California.

That's not to say you can't buy the splits and smaller things from from your Johnson supply from your slakey brothers, any of the other supply houses both if you wanted to be RV product you'd, have to come through Dorman right. This is the central controlling offering from Dai kinases or my clutch manager. It's the central screen right. It gives you the the overview of what the Dyken system is doing.

You know it's a big 10 inch touchscreen, so that scares people sometimes, but really it's nothing. More than a touchscreen glorified thermostat can do scheduling. You can do it basic interlocking up from that. This is if we need to get some more in-depth controls.

I mean this is way go this everybody has seen, and most people have seen it. We use this for digital inputs, digital outputs, some analog inputs - if we need to do some specialized controls other than that, that's that's kind of Duncan's offering for the control world from factory now, there's hundreds of different options for other equipment. If you wanted to integrate, everybody knows what this is. This is a Jase.

Do whatever you need to do, control it right. These devices can be either back my clients or back end servers. So we can pull points in there. Push points out for those of you who have ever worked with a relay.

This is basically, this is really smart relays and it gives you just a lot more control over whatever it is that you're trying to grow. Also, when we're talking really big like this, it's not like we're trying to hide information from you. It's literally just very open-ended. It's like using a whole bunch of 9340 s in order to control the whole bunch of different stuff.

You know so it's very it's. It seems complicated, but it's really not that scary moving on down the line, different control options, so this is this - is a product by cool master, to integrate with the Dyken system to get through to home automation stuff make it a lot easier, then continue down the Line these are going to be our single phase v RV technology sky air units - so it's gon na be smaller tonnage. Let's hook up to the end quote right above yeah is a particular interesting product. That's called a dzk Couture and I can zoning kit, so you can have four six or eight zones coming off of one fan: coil so really perfect for the residential market, if you're really trying to space safe space yeah and the one thing that I think a Question that comes up a lot with the difference between vrv and ductless, because it does become kind of a fine line when you're talking about single-phase and so on.

This is the metering device located and the condensers are located in the area right here. That's what I figured because that's usually sort of one of one of the primary distinctions, because people said well single-phase your v --! Isn't that just ductless, but when the metering device is in the air handler that sort of becomes vrv at that point. So if we want to continue on that topic right there, the the split would be right. We have our sky air systems, which would be what we're just talking about the vrv basically speech about that the unit.

If we go down to the last unit here, that's when we get into what people would consider conventional ductless right. So this is what we call a mini split. So this is a four part: tour America mini school, so you could have up to four heads off of one condensing unit and this. Yes, the expansion valves will be at the e-ring right, so you have the expansion valves outside and so now, both of your lines.

You know your one line is saturated, you know flask gas, liquid, vapor mix and then the other intersection line going back, but they're both cold lines, and there is some disadvantage in that again compared to the RV, because you do tend to have more losses and so You're lying length limits tend to be in line quite a bit quite a bit shorter. That's the number one call we get as the system won't communicate. They didn't look at the install menu and say: hey. You've got 33 feet, RTFM read the fancy manual, so we've got sealing cassettes here.

We've got all different types of fan: coil / air handling units. Let's talk a little bit about cuz when somebody sees these condensers, these big VRP condensers they get freaked out because they look so much different. But is there anything that you need to know like if you were gon na work on one of these? You touched on right here. I read the book right that the the biggest thing we could tell people is if the piping network on the side follows the rules that Duncan sets forth, which are pretty simple, there's really nothing to worry about proper airflow coming out of the condenser keeping the coil Clean right, that's big service things right, she's just got to keep the coils clean in four and a half years of doing this, I mean obviously move everybody's seen their fair share for pressure change outs, but major failures.

I remember not really seen many install them right in the first place. Keep them clean wire them upright, set up the controls properly, and you do a lot of that sort of initial commissioning and setup for a contractor thing yeah. So the most common thing we see is they don't have power right, there's no line voltage and the communication wire is not landed or it's not run or it's not landed on the right place. That's the most common things we see.

Is we get this you for error code, which is just a general communication error rate and nine times out of ten? Is somebody didn't turn the disconnect on? No, it is not talking, and then you have. This is actually interesting because they just heard about this recently. So tell us a little bit about this. This is a project, that's probably about four years old.

At this point, though, what we take is we take a conventional heat pump right. This is our version of a heat pump right to pipe system, and you can hook up an external expansion valve to it and hook it up to an existing air handler as long as the coil meets the spec. So this is just a regular Dyke envision air handler with the coil in it. That is now a vrv air handler right.

So you can, I think, the biggest one we did was 26 tons at 14,000 CFM right. So that's up the air handler yeah because in vrv most of the intelligence is going to be in the controls in the condenser yeah, the condenser. You know that's the brains of the operation, yep, very cool, so obviously anytime you're dealing with vrb anytime. You have drives and equipment.

You have to be really careful because you've got pretty high voltages in there Patong thing very high DC voltage upwards of 750 volts DC, so it okay, you could wake you up in the morning. No all right! Well, that's! That's that anything else. Anything else you want to show us here all of our product offering is we have one of every fan coil, except for the brand-new ones in our operation here, and we have our vintage equipment on this side sounds great. So, Norman s right, training center here in beautiful Oakland California yeah, if you ever, are in need of anything like this in California, the other guys to come to, and I really appreciate them, helping us out by hosting this training event.

So Thank You Donald. I appreciate it absolutely.
