Everybody Welcome Back Final Day of the Symposium Fourth Annual Symposium And uh Emerson has come back this time with some cool things, right? White Rogers has come out with uh, some incredible boards, some sweet replacement items for your unit, and uh Jim Here is going to tell us a little bit about about what he has and you guys can't be here to actually see this in person. So we want to go over some of these products and at the same time you guys are here giving back to what we're doing, actually helping out and training and helping out in the investment of the industry clearly care about the industry. So what has White Rogers done recently? What's one of the most recent things you guys have put out? Well, thank you for the opportunity to chat here today! Our newest control we have on a simulator here and this control. It replaces the 50m56u843 which is a single stage PSI HSI excuse me PSC All these acronyms, Um, yeah and and for lack of understanding them, let's spell those out.
The the 50m56 U843 is the single stage hot surface ignition integrated furnace control. There you go. Uh, there's also another control that we made which was a 50 X 57 843 which was a single stage hot surface ignition integrated furnace control for X13s or Ecmx controls. Okay, and we've taken both of those controls and put them together into one control.
So our one control now does both PSE and or permanent split capacitor and X13 Ecmx controls all together in one. The other other thing that as I was out in The field and talking with technicians. The biggest anxiety was this bag of harnesses that you had to figure which harness do I need to make this board work with my existing furnace and its harness. How to you know? The adaption of that was something that was a little anxiety to get through for sure.
and with this there's no harnesses in the Box We totally eliminated all of the harnesses and on the control. This area right here is for like the low voltage for like the limit circuits, the pressure switch circuit, and all of those circuits. There's five options there and you install this plug-in whatever harness the existing furnace has directly into the board. it'll only fit one of the five and and the same way with the hot surface, igniter and inducer.
there's options up here. There's multiple options here to directly plug in whatever style you have so you don't need a harness. And the next question is well, how does the board know what I'm plugging in and we've actually built that into the control so that the first time that the board Powers up it's going to look at those plugs and and see which plug has something connected to it and it will configure itself internally for those plugs. so there's There's no dip switches, there's no any type of adjustment.
It's What I Call Auto Harness configuration: It automatically configures itself to whatever harness is in there. That's awesome. All right. So I can say like we we did, we put this in our furnace I wanted to test out the board and it was just plug and play. It wasn't this plug for us, it was this one the 11 Pin from carrier and it was just plug and play and then igniter plugs straight in and you have you even have like the plugs are exact like you can't turn them and put them in the wrong way. It's not. There's not an easy way to mess this up. correct? Yeah, so yeah.
and and you look at it and say well there's two that are the same like the one this is plugged in below, they're they're 12 pin molexes. yeah but they're different colors and if you actually look internally in them, one has male pins in it, the other has female pins in it. so if you tried to plug in the other one they're not even going to work. they're not going to go together.
So it's the same as as almost impossible to plug in the wrong one. So the uh, the other feature we have on here is is our little thermostat bus which you can unplug and it's actually got some wires hooked up to it but all of the the thermostat wires connect directly to this so you can actually be connecting your thermostat wires out a way further. Make sure everything's good and tight and then come in and plug it into the board after you've got all your thermostat wires. Just make it a little simpler.
The board also has the test pins for the flame sense. so and it's the same as all the rest of the boards that we've been making. Currently, you don't have to have a DC microamp meter, you just have to have a DC meter nice and a standard DC meter. You put your probes on the pins and it's a conversion ratio of one microamp to a one volt.
DC So you can do a direct conversion on it. but we'll fire this up here right now because there's another really cool feature that that I like to share with this and the simulator is set up. So once we turn the thermostat up, we'll actually go through the process and and the there's a digital LED I Don't know if the camera can can catch that low or not. Yeah, but it will actually read what's going on.
So right now it's showing that it's in the heat mode in pre-purge PR and the pre-purge would be the inducer running 20 30 seconds. whatever that that it's set up for. Now, the inducer settings can be changed on this, but 90 percent 90 actually more like 99 of all Ifcs have one standard inducer setting on pre-purge and a purge and post Purge And so if you see those settings as an option to change, typically, you don't Have to worry about them because you don't. If you have, this is the most common.
it's going to be safe. Yeah, yeah, exactly So and we're continuing to run here, it should show trial for ignition igniter and I don't know if the the the camera can get there's a little blue flame there and that will get warm up there. Yeah, that feels great. Yeah.
Wow. I Literally we have our own little mini furnace right here. I mean this is the cutest thing I've ever seen. So so the flame Rod right here is picking up that there's flame present keeping the burner on. This is the real cool feature that I really really like about this board. Okay, the LED display right now is telling us that it's in the heat mode, but it's alternating between showing heat mode and microamp current. Okay so there if you look at this it'll have a little or a Capital C and it'll have a digit dot digit. Yep, and that's telling you exactly what your micro so you don't even have to pull a meter out to see if your flame sense has got a good reading or not.
That's incredible. It's telling us right directly on the board exactly what we have so that makes that takes one more step out of the technician and of having to do something that he should be doing on your your flame sensor amps. That's just incredible. I Love it! So and and what I like to share about that is is what you can do is when you commission this, when you first install it, you can document on the furnace what the flame sense is so that the tech coming back in the fall to do any type of a tune-up can look and see what it was when it was installed new and they can say oh yeah, it's dropped a little bit or no, it's holding steady and and when they clean the flame sense during the tune-up it should be back up to where it was at.
They know if if the flame Rod itself is good or not the flame Rod if if they do have a bad one, if they have one that's that's Rusty or or the surface is compromised. We also came out with Universal Flame Rods here this last year and our Universal flame Rod I Think you've shared some on your channel already that they're bendable. They're cutting really easy to use, really easy to install. Yep, the instructions are really straightforward.
Yep, it's something that's going to be on every truck that if you guys are doing furnace work, get one of these flame sensors, put it on every single truck. Yeah, it's it's that easy to put in. It has the instructions that actually match manufacturer flame sensor type so it'll walk you through it too. So it does.
Makes it really easy. I Always like to add that if you're doing a flame sense and you have to bend it, look where the little flange plate is and the screw hole is and make sure that your Bend is in the same direction from your screw hole as the old one. You might have the right angle, but it it. and when you go to screw it in, it'll be just angular.
Your flame sense might be going down instead of up in front of the burner and it shows you that in the instructions, where to lay it, where to actually put your screw in the front engine, that and which angle to bend it out and not to worry if you happen to bend it the wrong way, you can tweak it and turn it the other way. You may have a little bit of a dip there. a little little odd shape, but it doesn't have to be used. It does not have to be perfect like the OEM as long as the sensor probe itself is in the flame. As long as you got a good bit in the plane the flame just like the old one, you're good to go. So uh, one thing that I Just noticed watching the hot surface igniter. Come on. Um, not all hot surface ignitas are the same voltage.
So what do you guys do to solve that problem with the board? So this board here comes with a hot surface igniter with it which is a good idea if you're replacing a board anyway. it it is. So our original our original board was a 5855 843. Yeah, the 55 is the one for 120 volts.
the 5865 would be the one for 80 volts ignition hot surface igniter. So those and we still make those Okay, we actually still move a good bit of the 5855 and I think part of the reason we we do is because the cross reference isn't as great, but it doesn't come with the hot surface igniter. So if you don't need the hot surface igniter on the job, sure you have a control that's taking care of the customer and you're saving that expense for that hot surfacing iron. Now if you're going to use it anyway, whether you use it on the job you you're on or save it and and sell it on another job, that's up to you.
but that does give you the option. That was one of my favorite things. In opening the package was just the fact that if I have this on my van I'm gonna have everything I need for whatever situation and so you've got a customer stuck without heat. And one of the few things that as a technician we can't fix is when that circuit board has gone down and the frustration of being like we got to order this.
You got to figure something out for tonight. like the pipes in your house are going to freeze. I'm sorry. yeah like yeah that.
but uh, actually having a um replacement option on your truck that covers everything? All your options. Yeah, that's great. So it also has NFC on it. Okay and NFC we introduced last year with Allspark and All Spark is a spark ignition module and that module only works with the burner compartment of a furnace.
There's nothing to do with with the blower. there's no blower settings on all spark and so all of the NFC app configurations dealt with the burner side of things. With this, the only adjustable portion of the burner area is that inducer Purge time. This NFC is designed for the blower side of things and so when you go into to that and I I got the app right here we'll we'll bring it up really quick.
WR Connect is is the app. We actually have a QR code on the front of the controls so that you can scan that to get the app. you hit connect to control and I'll actually have to turn it off because it it will connect. but I like to to make sure that it's off I know for like all spark, you can't connect to it when it's sparking.
the the NFC is this disconnected? Yeah, a little privacy here. Yeah. so so we're ready to connect. Put our phone up here and it says data read successfully So the first time you're reading the data and the first item is the blower selection menu and with that that's where you choose whether you have a PSC or an Ecmx blower. Okay, and you can, you can determine or choose how many speeds that you're working with. this. uh in in that that's one of the things that when you're setting these up you need to go in and make sure that's accurate. The other thing that I share is the heat off delay and all of the old boards that are out there.
the vast majority of them. They're not a factory set number. Yeah, your old boards either have dip switches or or pins or something. Their jumper where you can adjust from 60 to 180 typically seconds of the band off delay, right? And so this, if you was to set this and say this is exactly like the old board, it still doesn't know how many seconds that fan off delay was, so you still need to look at the old board and match it in here.
Okay, to make sure that those match most of the rest of the settings in here if you're wanting to adjust the the cool on or off, the heat on or the fan on off. All of those are adjustable within the app. The the other cool part about the app is you do have the the Diagnostics tab so that if there's any errors that occurred within the last 14 days, they would show up on the app and if you hit the little information button it'll tell you what the error code meant and I'll give you a little direction of troubleshooting so you know what what direction to go to. One of the things I notice is just pulling the board straight out of the out of the box I could take the phone, the app and disconnect right there like you obviously have some sort of built-in battery.
Well so it Powers up. So so that's a good. That's a good point. American Express Does this have a battery in it? No, it doesn't.
So so when you go to to the store and you take this and you tap it on that card reader, it's taken your card number, your expiration date, all of your data and it's pulling it into that reader. Only one of the two devices have to have power. That's right. So with your phone having power, no power is needed in in the board for that to function.
That's pretty cool. So there there are the the app is continuing to be updated and we're in continuing to improve it and the only thing that we Mo you might experience out there from time to time is if you are connecting without power you can get an error code on a rare occasion that can show up and the solution is really simple. All you got to do is get the 24 volts to the control and once you get power to it, then you can go back and read it again and you're good to go. So most of the time you can set it up without the power right.
but again, that's that's just part of of brand new technology. We're diving into something that's never been done in the industry before. Uh, in uh, it was just a fun little thing. I was like okay I like that? Yeah, but yeah. yeah. but the point. and I think the takeaway is just how Universal this is and how simple it is to have something on your truck. It's an immediate solution.
It's an immediate answer to the problem that any technician is not going to feel intimidated. You put that in there and it's Plug and Play A pretty straightforward setup. so yeah, that that makes it simple. and and along with that, when it first came out, you would read it.
It would take two or three seconds to read it and then when you was taking and making the configuration changes and pushing it back in. I Explained it was kind of like downloading a new app on your phone. It's more than a 16 digit credit card number that you're just tapping. It's something that takes a few seconds to load in.
The original uh, upload time was about 10 seconds. Okay, and we have got that down closer to five seconds. So we're improving that we're working on. we're continuing to work on improving that every every opportunity we have to to lower that amount of time and and make it faster and easier to to make that connection.
Sweet. So yeah. Great Cool. Great new features.
550 Cross references on that and part of the reason of that large number is the fact that some of those controls are 80 volt controls and and the rest of them are are the 120. And actually we have one of the boxes right here. Uh, on on this this box you can see part of those control numbers right here on the side of the Box This doesn't have all of them. Yeah.
So if you're wanting the complete list or if you're wanting to to check and make sure that it's compatible, it is compatible. Uh, WR Mobile is a wonderful tool for every technician. It's not only good for our control boards, you can look up thermostats, you can look up gas valves. I Had a technician tell me the other day that he was out on the job site had a bad gas valve.
Went to WR Mobile and found that there was what the replacement part number was and called the supply house and said hey, this is what I need and he's like well do you need me to cross that over for you or you're just like no, that's the the new part number and he says he says so if I get out to the job and it don't work I'm the one to blame. it's nobody else because I know that I've used the app from the manufacturer and it's exactly the cross that I need and just saves you that step in that time of doing it. Cool. So cool.
Well uh we appreciate you giving back and actually helping out what we're doing. and like the setup here. You can see this is a diagnostic setup so technicians here can come and play around. We got all pressure switches, you can see the error code on the board and and uh but yeah it's just I appreciate what you guys are doing here and what you've given back. So I appreciate you having us here and and love the event it's it's an awesome events here it uh after. yeah after coming a couple years it almost seemed when I got here it almost seemed like a family area. We're definitely a group that any one of of the instructors here you can walk up and have a conversation with. It's it's so awesome we're all.
We're all here to help any way we can. So thank you Appreciate uh, everything that you're doing here as well. Yeah, yep, all right well enjoy the last day. Thank you All right thanks for watching our video if you enjoyed it and got something out of it.

Love this. You know I'm already ordering it 😉
Do you guys still install 1 stage furnaces in US? Here in Canada most of the furnaces are two stage. But even single stage furnaces use blower motors with serial communication. Which is really sad. Some customers without heat for several days, for motors and boards are not interchangeable.
That makes things easy
Ice board for sure Service area Orleans??
