This video is brought to you by Sportland Quality, Integrity and tradition. We are all hands on deck this morning. We are getting ready to change this package unit so we've got it disconnected, the gas unhooked economizer folded in. We're just getting ready waiting for the crane to get here.

The new equipment's here. The the guy that's going to remove the units is here or take the old unit. Um, we're just waiting for the crane. He? yeah.

oh I N so I'm going to stop the video real quick and I just want to start out with you know, wishing everybody a Happy New Year This is the first video of the New Year I Got to say thank you very much all for last year. All the views, the comments, the encouragement I got from everybody. It's really awesome. Never planned on any of this but again thank you so very much.

Um, if you haven't already and you're interested in doing so, uh I'd Highly encourage you to check check out my website Hvacr Videos.com There's links in the show notes of this video too, but we have a lot of merchandise on there. It's a great way to help support the channel. This hat being our number one seller black Underbill. it's hard to explain, but this is a see-through material, but it's not a trucker hat.

Um, super popular. The black underbill is like my favorite thing about it. CU There's nothing worse than working with dirty hands and then grabbing the underside of your hat. We also have some other hats available too.

We have the dad hat. The actual uh, this one right here is like a clasp. It's for with like really short heads. Not like normal people like me that have giant foreheads.

um, but bald people. Very popular with those ones. My buddy Bill Russell who's just, you know, extremely bald ever since he was like four years old has that. but uh.

we also have the flat bill. This one is a snapback Flex Fit Uh, it's not the see-through breathable material though, like this one. Um, also have beanies cuffed non-cuffed again. Hvacr videos.com We're going to go A and get back on with the video.

Thank you so very much and again happy new here. All right! We got the new unit set. This is our first install with the core controller, so that'll be interesting. Um, it's a like for like unit, so electrical and everything comes up in the same spot.

so we're just in the process. So bring main power into the disconnect, hook up the gas line, hook up the drain line, put together the outside uh, economizer, the outdoor air eyebrow. So that's what we're all working on right now when it comes to the electrical. If you have long like I have long electrical I prefer there to be excess as long as it's not going to rub out.

So I need to do some work to make sure that these aren't going to rub together, but it leaves a little extra for in case you have a burnt connection or something like that. We uh, got all the electrical done we're working on that. We're doing the gas line right now I got some of the Nyog white thread sealant stuff. does pretty good.

Put it on there and then we'll uh finish fitting the gas line. All right here we go. Um 1 Two 3. Please don't blow up.

Okay, so far nothing's blown up. This unit shouldn't do anything and then we're going to check phase rotation right here. So what we're going to do is uh, connect. We're using the field piece Sc480 and we're going to go right here.

You want to come do this? Phase rotation will? Yeah. Do it Right in here. So 1: Two 206 Wait for it to tell us it's Line 1 Two 3 So it says that it's phased correctly. We'll find out a little bit more.

What we'll do is Bump a compressor real quick. It sounds good, doesn't sound bad. So I think the phase rotation is correct. Now we need to go ahead and connect to this guy which it says pair right here.

So we're going to hit Pair. Follow the instructions. um press pair button, wait 5 seconds and release it. Let's see what happens here and it looks like it's pairing right now.

Maybe click next. Once You are ready and let's see if it finds the Rtu. it's looking for it. Nothing yet detected within 50 ft.

So you want? Maybe we need? Maybe it was supposed to be blue? that's not connecting what is going on here? Sure. I'm doing something wrong. Hold on I Power cycled the unit I Want to see if we get that blue light again and then maybe I'm not supposed to push the pair button. It says give it a minute and we'll try.

All right. We got the blue button again, so I'm curious. If so that's what I'm confused by Maybe I'm too close. Let's try moving this over here.

Start over Okay So if you have just powered on the RT wait 2 minutes for boot up completion, press the pair button for 5 seconds, then release it. But what's interesting? Oh so now it's now it's green I wonder let's try again. Start over. No, what is going on here? One Mississippi Two, Mississippi 3, Mississippi, 4, Mississippi 5 Mississippi Ah, maybe that's what it is.

Okay, now let's try there. We go Now it's working oakly doy. Okay, looks like we are paired now. Uh, it says to check to make make sure you have the most recent firmware.

update I Don't know how to do that but we paired it so we're going to hit finish and now we're just going to go through programming I'm assuming so it tells you what you need right here. We're unoccupied at the moment. We still need to program our thermostat too. Outdoor air temperature damper position: Unoccupied.

Okay, let's go here. I Mean there's not really a whole lot here for us to do. Ah, there we go. Okay, so maybe I can set the unit up.

You can do component test through this. Okay, so that's not too bad. Maybe I'll go through install new unit setup. There we go next.

let's scroll through it. today. Is that today's date? No. what is today's date? Oh that's odd.

Oh there you go it is. December 28 28th, 2023. Done There we go and our time right now. What time is it? 9:00 900 a.m.

Done. Use mobile device. Date and time. Oh that's pretty cool.

All right. Next: Uh, Rtu name. We're going to call it Bar AC R AC I Just call it Bar. There you go.

Serial number. That's all right. Done Next, That's not too bad. I Mean it's just really just walking you through all the steps here.

Um, configuration. Okay, so that's the settings that the unit has. I'm going to verify via the door that that's correct. That's going to be the economizer.

All that good stuff. So I'm going to go verify that real quick. All right Configuration: IDE is correct. Uh, okay.

Dehumidification mode disabled? That's correct. You know. What's interesting is this unit on the panel. where's it at? right here? it's labeled humiditrol.

This is not a humiditrol unit. There's no reheat. you come in here I think they mislabeled it. there is no reheat and I don't see a reheat coil I don't see extra discharge lines.

there's nothing. so they labeled it wrong as humiditrol. We didn't order humiditrol so I was confused when I saw that this morning. I was like we didn't order humiditrol.

So let's go down here. High efficiency. Yeah, no, they did not order a humiditrol fresh air tempering kit. it says factory installed I didn't see that I was curious where that was at I don't see my Supply Air sensor I mean there's the basic Supply Air sensor right here here.

but when they do fresh air tempering, they usually want you to install the discharge air sensor like you know, far down in the duct work. and I have the the fresh air sensor from the old unit. but I don't have it I don't know, whatever. we'll deal with that later.

but yeah, I don't see any humiditrol in here. They do have sensors which is new but yeah, I don't see humiditrol, don't see a reheat coil or do I no I don't think I see reheat. No, that's odd all right. So we're good there and it's just waiting for the unit to get a call for cool or heat.

and I have will going down there to program the unit. Everything looks good. We look good, finish and we are pretty much ready to go. We can go.

We do have to program the thermostat and stuff I mean the economizer, but we're going to do that in a few minutes. So I'm going to wait for Will to finish up the thermostat programming. We'll get a call for cool and then we'll go in and do what we have to do to program the uh outside air damper and stuff. All right.

the blower came on. it's running in the right direction so that's good. The way we have this unit set up is G is my occupied signal. so from G goes to Ocp.

It's really important to have that occupied signal cuz you have features in the unit that won't work right if it doesn't have an occupied signal. So however you need to do it, some building automation system might run occupied and then let the unit. Take Over Control this one. We're going to be using the thermostat downstairs.

So um, as far as doing the upgrade over USB I thought maybe it would do it through my tablet, but no, it's asking for a uh a USB cable and I don't have one of those so we're just going to run with it the way it is right now. Um man, they sure have like a lot of stuff packed in this unit. Granted this is a 17 1/2 ton but my goodness gracious, look at that Rat's Nest wires. Holy majoli, that's going to be a mess.

Interesting though. huh? Um, Okay, Well, we're just waiting for a full call for Cool, which he should have in a few minutes. All right, we got a call for Y1. just this compressor.

There's Y. Oh no, that's the second stage for Y1 and then the other two will be dead. So we're doing good there. Um, Canel.

Next, turning the blower on near people could result in serious injury. Okay, Cancel. We don't need to deal with the blower right now. Oh, I think I just did that because cancel Cancel I don't need to make that change.

but it is cool that you can do the blower speeds and everything in this unit. Um, that's really neat. So you can go and set the blower speeds cuz this does have a two-speed blower via that guy right there from the Vfd. so it slows down and speeds up.

BAS Bas On the demand for cooling and heating to try to be more efficient while we're waiting, we know we're getting a call for cool. So let's go ahead and set our economizer options. Um, that's the offset. We don't need to worry about that and then set free Cooling Supply Air Set point: We're going to go a little bit lower I'm a little more aggressive on my free cooling, so 50 it'll go free cooling next and then, uh, ventilation options? Um, um, we'll leave that where it's at and then that's when it's going to open.

Demand control ventilation. We're good with all that. We'll leave that where it is. Uh Fresh Air Heating on Fresh Air heating set point So anytime it gets to 40 in the duct work, it's going to uh, bump the Fresh Air heating on anytime it gets above 90 and the duct work for cooling, it's going to bump the cooling on that way.

they don't just blast people with cold air so that's cool. Do that all right. This is really cool. uh I Do have to say that I Like the core controller, so far so far it's not difficult to operate at all.

Currently doing a damper. we're uh, calibrating the damper opening and closing. So right now it's opening so this is cool. Once it's fully open, you can just hit confirm so you can see it's slowly opening right now and then once it gets to open, we'll hit confirm and then we'll be able to set our minimum outside air position.

All right. We are opened all the way so we can hit next turn. Blower on Blower's coming on minimum damper position This is uh highp speeed so they got to get test and Air Balance over here. But basically I can come in here and make adjustments for now and get it where I think it needs to be and then test and balance will have to uh dial in what they want.

All right, we are good damper set up. Uh, we do have a demand right now. we need to give the unit a minute. There we go.

a demand for G and y1 So I really like that. it gives you all the information right there. That's really cool. So they make it really easy going through this because local thermostat inputs.

So that's basically what your LEDs are saying right there, which you guys can't see very well. Um, but then you can go to sensors or set points like let's say you want to do where the unit has its own control. Okay, and you just give it an occupied signal, then the units, sensors and everything take over. You can set up your occupied and your unoccupied Heating and Cooling set points.

All that good stuff. So if you didn't know, that's one thing about the Linux units. it really easy. Even on the old L Series units, you're able to put them in Standalone mode where all you got to do is give it an occupied signal to say that someone's in the building.

and when you do that, you don't need all the other thermostat wires, the unit will run itself. So if you ever have a bad thermostat on a weekend and you don't have one, you can actually just go into the unit. I've done that before. Get you through the weekend, just set your run times, you know I mean shoot, even uh, when I did it on the weekend I didn't have an occupied signal so I just gave it a permanent occupied signal and just had it maintained 75 and 68 for the weekend and then came back out and changed the stat.

But it makes it really easy cuz you can just simply do it and you don't have to get into all the real programming of the unit. You don't have to go through the trees from the prod. One Controller that would get confusing so that's really neat. Pretty cool.

You could do the testing too. Heating and Cooling So we went into component tests and then we're testing heat right now, firing out the heaters. So we're only doing first stage right now so we're just waiting for it to turn on. Look like we got to clean up a few dribbles.

but I like it. I Like this core controller so far. we're burning off the heat exchangers right now. but but we're walking around and we were looking.

From the looks of it, it looks like maybe we have two ECM condenser fan motors and two regular condenser fan motors because there's only two capacitors. But we're looking in here and these nuts for the condenser fan motors are all loose. Every one of them they didn't get tightened on. Well, that would have been a problem.

Micr: Channel Condenser condenser fan motor drops down, but all the way around every single one is loose so we got to get up there and tighten these all. That's crazy. That's why you check this stuff. Every condenser fan motor, all four bolts were loose to the point that after a little bit of runtime, those things potentially could have fallen out and that wouldn't have been good because in the middle of the summer, it would have ruined a microchannel condenser someone over at.

Linux Went on lunch a little early, huh? Probably the same person that marked this unit as a humiditrol. When it's not a humiditrol unit. let's see this. Yeah, it's doing both.

Okay cool. So that's good to know on component test. No, it's only doing one side. Oh is it oh so I'm interesting.

Something that I'm realizing is they don't have a at least I haven't found it yet. a full call for heating. So I did second stage and I was wondering if the first stage would come on too. but no, only the second stage is running.

But another thing that I just noticed this restaurant's been in existence for 20 plus years is that the combustion air vent blows right into the makeup air for the building. Oh wait, did this just light. Oh, it did just light. Okay, so that makes more sense.

Heating stage two does both stages. That makes a lot of sense there because when you're doing a routine maintenance or something, you want to fire them up into full heat. Full cool. you want to be able to do that.

So when you go into component test, just do second stage heat and then it does the first stage too. Now we're doing a cooling test. so we put it into stage four and it's turning everything on. What I'm confused by though is right here.

It says blower percent 25% blower speed I Don't know why it would say that for all four stages, but it's not doing it that low. It's running at 54 Herz So Okay So we've got all four compressors on warm discharge lines they all just came on I Just want to make sure everything's good. Let's go down here: Discharge Air temperatures. What information does it give me? Return Air temperature.

Okay, so it really doesn't tell you anything besides return and Supply temp. It doesn't let you like look in and look at the data or the vitals. which kind of sucks because if they're measuring super heat, why can't I read it? Although, they probably don't have pressure transducers, so no, they're not measuring super heat. But yeah, all right.

Well, we're cooling cooling. It's a rather cold outside to be really doing a whole lot with that, but that's cool all right. Well for now I Think that's going to be it again. we're going to be coming back with test and Air Balance we're going to be coming back with the fire alarm company.

All that good stuff. but for us today, this unit is installed and it is operating and the customer's happy. Uh this is the first time I've done a Linux core controller and I have to say so far, super easy I like it I don't like the messiness of all the wires like that. That's chaos.

pure chaos I don't know what this is about like I think they were trying to make it look neater but it just makes it look sloppier. but all right. Well oh another thing too is they used uh Ferals or whatever those are so those are kind of cool thr all the wires instead of just crushing down on the wires you actually got little terminals so that's neat. Well we are good to go I don't think that went too bad at all.

Surprisingly it it the whole process was a lot faster than I thought it was going to be I thought that uh change out itself was going to take more of the day but it's nice when it's a like for like replacement in that situation. So um, as I'm editing the video I realized that you know and I mentioned in the video too. There's a few things that I didn't show. You know these videos are not like I don't go into these thinking like okay, I'm going to show the entire process.

This is a step by step of course. I you know I try to show a few little highlights here and there but I my main priority is actually doing the work right. Um, you know and I know a lot of people people ask me like hey, how come I don't shoot with like a GoPro where you can get a first person view that kind of stuff. um honestly GoPros are a pain in the butt.

They really are. It's so easy to film with my phone. it really is and if you get you know into a routine like filming and cutting and continuing, it's just super easy. So I have a bunch of GoPros but it's always difficult.

The other thing about GoPros is they tend to to film in a much wider angle and uh, when you have first person perspective, it's really difficult for someone that gets motion sickness to edit those and that's one of the big things too is cuz I get motion sickness. So as I'm watching this trying to edit it, it's very difficult and I know there's going to be a lot of people. How come I don't get an editor? Well finding an editor that can actually edit technical videos is impossible. Like damn near impossible.

Okay yeah you know I can find an HVAC service technician that likes to edit. Then it runs into the problem I'm editing in 4k I'm using Adobe Premiere Pro like and so that just adds a lot more issues and and red tape to the whole thing you know, of course anybody can you know get cap, cut and edit and do this different stuff, but it's not doing it in 4k. It's not using the right file sizes like it just gets really complicated. So um, my brain basically makes everything really complicated.

that's typically how it is. but I I I Do wish there was a better way to film first person perspective because I wouldn't mind doing it every once in a while and certainly it would help me. but you know it is what it is. I'm going off on a tangent as usual.

thank you. You know, whatever. But um, now let's talk about the core controller. the core controller setting this unit up super easy.

I had some issues with the pairing process right and I kind of left that in there so you guys could see it. definitely with some clips that I cut out, but it was a little bit longer with the whole pairing thing. If you follow their instructions, it makes it seem like it's super easy, but it is a little bit difficult trying to figure out the pairing thing. but once you do it once, it probably is pretty easy after that point.

But I mean once I got past the pairing stuff like setting that unit up was super easy and one of the most important things that I think needs to be mentioned. and this is not an paid endorsement or anything like that I got no affiliation with Linux Okay, um is that you don't need a username or a login to access the unit. which is huge. Okay, there's some manufacturers out there.

Um, that put everything behind a pay wall or make you have their specific software. Um, this one is relatively easy to set up. Didn't need a a login or anything, just had to be so close to the unit, scan the QR code or recognize the unit like it was super easy. Um.

I Also see some potential problems with that I would have to, you know, explore a little bit more to make sure that there's like password protection. Now, this unit is not connected to a network so nobody can access it from the internet. but you know I don't know. Like I Guess the Bluetooth signal from the unit's not that strong so you do have to be probably within 10 15 ft of the unit.

So anyways, that's a another problem for another day. set the unit up. We did find some issues. Okay, uh.

number one I realized in editing this video you did not see me tap the Transformers That is one of the more important things when you're working on these package units. they typically come tapped for 230 volts in this situation or 240 volt. Um, I had to drop it down the tap to 208. Uh.

realized I didn't show that in the video, but we did get that done. The next thing is, you did not see me do a full heat startup on this unit where we tested gas pressures and checked all that. that happened actually the next day when we went back out there. uh, had someone else go back out there and do the heat startup.

So I didn't get that on film but always important, you know? I I realize when I'm editing these things that there's certain things and I usually catch it. Um, other than that, the startup of this unit was pretty seamless. Uh, it went to be a good day. You know it's important before we do these jobs.

everybody knows their, uh, you know their tasks that they need to complete for the day we have safety meeting. Everybody knows. Be care careful, don't get under the load, you know that kind of stuff. Um, and everything went seamlessly.

Often times you're working super early in the morning because this one, uh, shopping mall, they didn't want anybody in the building. We had to take all the customer or the yeah, the customer had to come out of the building and stand and watch. uh, they wanted. We had to rope off the parking lot like it was this big old, long, lengthy, ridiculous process.

That was kind of unnecessary. but whatever, you know. So we had to do an early early morning start. Um, so it's kind of cool to see the sunrise as you're going up, But overall I think this job went well.

uh, was very uh happy with the Linux core controller. Super easy to use. Uh Linux definitely needs to fix a few things you know. the unit was labeled a humiditrol when it wasn't a humiditrol unit.

Okay actually when it was sitting on the truck in the parking lot cuz I got there like an hour and a half before the job cuz I'm a Nut right? So I was sitting here and the the delivery truck was already there. so I was over there inspecting the unit, checking out, making sure it was gas heat. That's a story for another day. Ask me on one of my live shows whether it be my live stream or the HVAC overtime show about the unit that I installed that had the wrong heat package on it.

That was a mess. but anyways. um when I was in the parking lot I was looking and I was like man I didn't order a humiditrol like that's not right, you know? So I was like thinking about refusing the unit. good thing I didn't right because I get in there and it wasn't a humiditrol.

it was just labeled wrong. Okay, uh. and then the other thing was those condenser fan motor brackets. So I don't know if the video really explained what it was.

that's the entire bracket assembly for the condenser fan motor. so it has a bracket that comes down and there's little bolts that go through and everyone. The Nets were loose so over time that unit running it's going to vibrate, Those things would have fallen out. not a good thing.

so they definitely need to work on their quality control. Make sure that they're catching that stuff before it leaves the factory. Luckily we were checking a few things so we went around made sure that we tightened up all the lugs, set screws, and everything just to be sure. But other than that, this was a great job.

It all went well. I'm thankful that everything happened the way that it did and I'm very thankful for you the viewers because you guys watch these videos consistently. Thank you so very much!
