Black we've got our yellow and then this one here is kind of hard to see it's a little bit sun bleach, but this is a brown, so this is going to our start. Winding of our condenser fan motor. This is run. This is common and down here.

Similarly, if blue is going to our start, yellow is going to our run. Black is going to our common okay. So today we're going to take a look at this carrier straight wheel, unit, very simple system. We're gon na look at it through the eyes of understanding.

Schematics, specifically so buddy those are the schematic, we're going to point out some of the components and hopefully give you a little bit of a kind of a grasp, but just the basics. It can be very simple, but this is the way to really learn how to read schematics and diagrams always pulled it. Isn't it and then reconfirm to make sure that voltage is actually off to ground and late? Today they say here we have a connection diagram and asking at a schematic diagram that show essentially the same thing on a connection. Diagram are l1 and l2.

These dashed lines that means field connected power, they're coming in the side here, in order to look more like real life, whereas here you're, connecting in between l1 and l2 on either side. So, let's start there we'll identify this l1 and l2, l1 and l2 as well as ground. That's the symbol for equipment ground that little pyramid gon na upside down pyramid blind. So let's identify a car.

I will still connect just come in. We've got our hell coming into our contactor. Next, let's take a look at our contact points. You can see that we have this, what we call a plus one, which is just a bar that goes across the contactor so on this.

That would be this side over here, because again, this is splitting it up based on l1 and l2, so that 23 and 23 it's gon na, be the same as over here and that is contactor here. That's this metal bar on the right side of the contactor! So that is 23 and 23 point see that mark there 23 and 23 on that factory contactor now we've got points 11 and 21. This is what breaks l1. These are our normally open contacts that then closed and we're gon na bring on the condenser in order to bring on the compressor and the outdoor fan motor.

We can also identify those over here. These are gon na be 11 and 21 sure enough 11:21. Our contacts right underneath there you can see our equipment grounding block. That's how that looks our run.

A connection diagram in here - that's gon na - be this terminal right here. That is our ground for safety. Next, let's take a look here at this crankcase heater circuit. Now we're gon na look for this extra black wire.

That goes from one side to the other you're gon na notice. These have stars on them. Ch, that's crankcase, heater CHS. Let's see what these say: they are ch, crankcase, heater, crankcase, heater switch and the star means.

Maybe factory or field installed, so that means that's not necessarily here sure enough. It is not here because, let's see, we don't have a black going to the other side circuit. All we have is our compressor condom right here. It's big wire.

This is air compressor common and then this is their condenser fan motor comfortable, so that is not present in this particular application. Let's take a look at our capacitor. This is another one. We've got our blue wire.

That goes to our start winding on our compressor. Let's see if we can find that on our capacitor shearing off this is our blue wire. This goes to the start, winding of our compressor, and you can see it's marked firm there now a lot of people misunderstand, and they think that the start winding is only in during start. This is known as a permanent split capacitor motor, a compressor, and so that start winding is actually in all the time, but the only power that can go in and out of the serve winding these power moves in and out of that run capacitor.

So, in this case, the start winding is actually connected to run on a run capacitor. This is called a run, capacitor sort of a confusing terminology there, another set of accessories you've got a ASR here. That is a start relay and an S see a start capacitor and an STI start semester notice. These all have stars on them.

So actually, in this case, this unit does not have any of these, but this could be a factory installed option and that's why it's shown here. These are actually not going to be in this piece of equipment. So, let's look at our next player here on our compressor: we've got our common, which is black, goes to C connected to terminal 21 and sure enough terminal 21. This is our compressor, this big wires, our compressor common and the small one is our condenser fan command.

Let's see if we can locate that one condenser fan comment goes to black and up to 21. So that's what we got now. That's you've got two yellows one goes to run on the compressor, so it goes to our run winding and that's right here, big one and then this yellow one, this other yellow one. Here, let's see it's, it says it's going to see on the capacitor.

Let's see if we can locate that one. So if we look here, there's C on the capacitor and there's that yellow wire going to term of under-23, you look over here, we can find that right here see if we can find that there is our see it's coming over here to terminal 23, because again This latter form schematic is setup where it's making the connection between l1 and l2 all the way across now. Let's see here, we've got some of our low voltage. Connections are shown here, so we got yellow, which is our compressor contactor.

It's going through all these controls. According to this, but you notice these all have stars low pressure switch DTS. What is that discharge temperature switch in HBS, which is our high pressure switch? So, let's see if we can find the yellow wire coming in sure enough, we get this yellow going to yellow and blue and that's just going directly to the contactor. So we're not.

We don't have any of those accessories in place. This is our 24 volt call from our thermostat. It's going straight to the contactor and the other side of the contactor, which is our 24 volt common. It's going straight over here and it's connecting to it looks like phasing black for coming here below is commonly used for common, often, but in this case they're using black.

So it's using black and yellow as our Yello call, which is contactor call and 24 volt common. So we've already identified everything inside this condenser. Let's go ahead inside this condenser panel. That's on this diagram.

We already pointed out every wire. So now, let's open it up and see what we've got on the inside black we've got our yellow and then this one here is kind of hard to see it's a little bit sun bleach, but this is a brown, so this is going to our start. Winding of our condenser fan motor, this is run. This is common and down here.

Similarly, if blue is going to our start, yellow is going to our run is going to our comment. Let's take a look at that on the diagram. Just show it once again: let's go up here to this schematic side Ron is doesn't show a color here, but it's going to terminal 23 start, as our blue C is our common and going to the other side, see if we can see it here there. It is black, is common.

Blue is start going to the run capacitor on the firm terminal and then yellow move to the other side of the contactor to run on the compressor outdoor fan motor yellow moving over here terminal 23 Brown. Let's go to the F terminal. Let's actually says opinion on the capacitor: that's that brown! That's our start and then black is our common going to the other side. So that's how you apply this and again, when you start with these, it's good to look down here and kind of pay attention to the notes.

Symbols are electrical representation; only they have inherent thermal protection, meaning that there's overloads thermal overloads tells you what size VA. The Transformers required there's lots of really good information on here and you'll find that it makes a lot more sense when you're working on a you know for the first time, especially if you're new to it to go through and understand everything. That's on here pay attention for there things that may not be present. They may just be on the diagram because they could be installed and you'll find that it makes a lot more sense.

That's a little basic connection and schematic diagram walk through and I carry your straight hole thanks for watching.
