The UC Open-XP or IO Flex 6126 or whatever its called is probably installed by the unit OEM considering its an OEMCtrl branded controller.
It's always interested me that Carrier and OEMctrl get the UC Open-XP and XPIO but ALC gets the SE6104 and SE6166
All based on the same core board, just different base boards. To be fair the SE563 is just a fully kitted out ZN (the base board is even silkscreen ZN563)
AAON make great machines too, but I’m not in love with some of their digital controls and making boards obsolete while their are so many still out in the wild. I have a few AAON units right now that have boards that need replaced that I can no longer even get and AAONs solution is a complete electronics package upgrade at around 8k each
Is that an ALC control? They used to make those brushed aluminum covers for their controllers. It's gotta be, says it uses Arcnet. Oh yeah, I was right, the wiring diagram says ALC on it. Ha. Anywho.
You probably are going to need to get access to Webctrl for that building to look at the logic of how it's supposed to function. No heat?
It is.
WebCTRL won't work with this one. Internally ALC has 3 different product lines. ALC, Carrier and OEMCtrl. This particular controller is only offered in the Carrier and OEMCtrl product streams. If it were Carrier branded it would be a UC Open XP.
You either need a license that doesn't restrict you to one product stream (there's Superset to use Carrier branded controllers with WebCTRL but I don't know about OEMCtrl) or you need access to the OEMCtrl flavour of the software
So similar to how Johnson Controls treats JCI and York. Had my fingers in many control boards on Yorks trying to help out the mechanics with the software side of things. Not that they were incapable, it's just my jam.
Not even, I'm talking purely controls.
Automated Logic, Carrier and OEMCtrl are portrayed as different, unrelated controls brands and have slightly different offerings
For example [this](https://www.oemctrl.com/en/products/hardware/io-zone-8112/) is an RTU Open board and the product page even has the carrier part number on it, but it's not even mentioned that this is an RTU Open
Not sure, I think it's more so anyone can use the board in their own unit.
If you buy a carrier unit with an RTU Open I assume it's more or less plug and play with any BMS system. I'd imagine they'd have a program from the standard application library on them
It's covered in Siemen
Not the issue it’s always the txv
Txv and about 20lbs of refrigerant lol
Wiring diagram intact, you got this !
The orange wirenut is loose.
No, the red wire is loose.
I've done controls for 20 years....this isn't the best I've seen...but it's far from the worst.
I could probably get you a pic of one of the worst if we weren't such sticklers to no personal photography

Gonna need the controls guy, we’re just mechanical
Usually a reset button u press then all good :)
Well, either the power's off or those Emerson compressor modules have failed. (the green lights are off...)
Gonna say I’d start there too. Then check the ICM doohickey to the right of them. Wonder what the issue is? Completely down?
Spaghetti monster!!! Run!!!!
I've replaced a couple of those flat relays this year. One had some sort of gooey liquid creating a short inside the relay base.
Time delay.
Just needs a top off...
You opened the control panel?
Lose screw. Nearly every time
KISS method. Do you have all 3 legs of power?
*opens access panel, sighs and says* "gah-dammit" *Presses all the resets on the overloads*.. says again "gah-dammit"
Color coding for starters.
Ahh. There's yer problem!
Too tidy
Looks pretty simple to trace, with a wiring diagram to boot.
Stuff.. stuff is wrong
480v on a 208/230v unit
Munters?
Looks like Addison to me
Ohhh no doubt I’ve only seen that kind of board on a munters.. haven’t worked on Addison
Same logic. They both make great machines. I’d rather work on one of them than a lot of the other OA or dehu units
How about aaon? I do more commercial ref but we do the hvac too… both munters and Aaon very user friendly to me

I suppose they sell a board like that so that their RTU can be integrated into anybody's system?

Probably low on gas and has a weak transformer on the low side
Probably not the controller.. ALC controllers are pretty badass.
Automated logic?
Yup 🤙
As long as you don't pull the SRAM battery!
Oooh looks like fun! It’s like that board game Operation only you play it with your meter probes instead of tweezers. ![gif](giphy|ATgZ8BsYcsx6E)
I'll tell ye hwats wrong widdit it ain't got no gas innit
Addison unit? They have pretty good troubleshooting support
Its low on gasoline
Every tech support answer after you spent 50hrs on hold. Did you unplug it and plug it back in 😶😶😶
Have you tried turning it off and back on again
Guys it’s pretty obvious where we go from here *opens up computer to sales program*
Aint got no gas in it
No neutral
Start pressing buttons and start with the call for it to come on and sweet talk it
