DUAL ELEMENT HEAT CONTROL PART 2
You're up to like 50 gallons. Let's get into building the P ID controller for a multiple element circuit. It may look like a hot mess but it really is straightforward. My transformer, my hot leg, and my neutral leg. When I plug it in the transformer is going to work and the fan will come because of a 12-volt. Now I've also added my donuts I just call it a donut. Its a sensor for the amp meter that I've put in.
I've put it on the main, a live wire coming in because you only put a sensor on one of the hot wires, everything else is relatively simple. My 120-volt receptacle got a neutral line. I've put a switch in the lid. So I've got hot and that's going to be the other hot that goes to the switch. So when I turn the switch on the light will on when I turn the switch off of course that'll be off. I know it looks like a hot mess inside but believe it or not, it all makes sense to me. There are my 230 amp twist lock receptacles and there's my 120-volt accessory.
I did was let the panel in the front panel. I've got a master’s power, that's a lighted master power and I've also got the light switch, which turns on the accessory. So the water pump, that'll turn that on and turn that off. They're going to control the elements but the P ID there's my amp and voltmeter in the plugin for the thermal probe. So this is going to work remember the two solid-state relays. I'm running around I got a hot wire going in from The red side and I've used all black because that's all I've got.
The 10 gauge wire that goes from the black into number one then from number two, it's that goes from it then to the receptacle from number two goes to the receptacle. the link goes actually to the receptacle, the one goes to this receptacle. Now the only thing I had to add it to another screw. I needed 120 volts to remember.
I got to take the hundred and 20 volts from the opposite leg. So the one comes from the leg and then the wire that goes to the leg and the same thing to others. The one goes to the leg and this one goes to the other leg. That gives me the 240 volts on each. I'll do is it for the switching, you know that the P ID is going to come when it's required, it is going to send the signal, two pins three and four in both the cases, because I'm just going to run them parallel.
As it turns on the P ID, it makes a connection of course, and then it energizes my element. What I'll do is I'll switch over on pin four, which will go to pin three on the P ID, pin four will go to pin three on the P ID. Pin three will first go to the switch.
It will just go to one of those screws on the switch then from the other side of that switch, it'll go to pin four on the P ID. and the same thing from pin three. I'll go to the other switch to one of the screws. And I'll go from the switch to pin four on the P ID. So remember, four goes to three and three goes to four on the P ID itself and that's for the month.
We'll get it all cleaned up and wired up. It’s completely wired and ready to go live. All the individual elements, element one, element two and it is for the ACC, your accessory water pump, whatever that maybe it’s the main power on and off. Now before we fire it up. Let me know what kind of plug you need in the end. In particular, is going to be the four-wire 100 and 240-volt four-wire. So it helps if you just take a picture of the receptacle you're going to plug it into but I just want to make sure that when you get it, you can plug it in and you can start working. So what we're going to do is we're going to add a plug on the end of it and we're going to plug it in.
My P ID, my dual-element p ID all assembled in to say I got my volt amp meter so I can keep track of. I could always use the P ID. It has a power output mode that you can track as well. The accessory for my water pump, my main power for my P ID when I turn that on, I rewired a different sort of fan would come on when I turn the P ID on it's really the only time I'll need it anyway. My controls for the irrelevant number one, it's flashing because it's requiring some heat or power. It will indicate every time that element is fired.
Every time I pee it fires at the lights. So that's just a visual indicator and it's manufactured and it goes McCool points.
