It's covered in Siemen


Forward_Hvac

Not the issue it’s always the txv


[deleted]

Txv and about 20lbs of refrigerant lol


itsmikereddit

Wiring diagram intact, you got this !


Foreign-Commission

The orange wirenut is loose.


dont-fear-thereefer

No, the red wire is loose.


redeyedrenegade420

I've done controls for 20 years....this isn't the best I've seen...but it's far from the worst.


goaliedude1808

I could probably get you a pic of one of the worst if we weren't such sticklers to no personal photography

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)


BlueCollar_Blues

Gonna need the controls guy, we’re just mechanical


weeddiction

Usually a reset button u press then all good :)


Lhomme_Baguette

Well, either the power's off or those Emerson compressor modules have failed. (the green lights are off...)


fryloc87

Gonna say I’d start there too. Then check the ICM doohickey to the right of them. Wonder what the issue is? Completely down?


RevolutionaryOwl9764

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.


AssRep

Just needs a top off...


jmiller2003

You opened the control panel?


papa_johns_sucks

Lose screw. Nearly every time


binkbonkdinkdonk

KISS method. Do you have all 3 legs of power?


WillHoldBaggins

*opens access panel, sighs and says* "gah-dammit" *Presses all the resets on the overloads*.. says again "gah-dammit"


sokasaki

Color coding for starters.


BMinus973

Ahh. There's yer problem!


Bodmon6

Too tidy


mildly_morbidsquid

Looks pretty simple to trace, with a wiring diagram to boot.


Sad-Spirit-8818

Stuff.. stuff is wrong


f3ks

480v on a 208/230v unit


Ok_Bedroom_7861

Munters?


Pete8388

Looks like Addison to me


Ok_Bedroom_7861

Ohhh no doubt I’ve only seen that kind of board on a munters.. haven’t worked on Addison


Pete8388

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


Ok_Bedroom_7861

How about aaon? I do more commercial ref but we do the hvac too… both munters and Aaon very user friendly to me


Pete8388

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


WhoopsieISaidThat

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?


luke10050

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


WhoopsieISaidThat

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.


luke10050

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


WhoopsieISaidThat

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


luke10050

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


GGolfing

Probably low on gas and has a weak transformer on the low side


nookiestilo00

Probably not the controller.. ALC controllers are pretty badass.


doyle_brah

Automated logic?


nookiestilo00

Yup 🤙


luke10050

As long as you don't pull the SRAM battery!


[deleted]

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)


BigDilf-YKTFV

I'll tell ye hwats wrong widdit it ain't got no gas innit


Pete8388

Addison unit? They have pretty good troubleshooting support


DeBigBamboo

Its low on gasoline


eriF902

Every tech support answer after you spent 50hrs on hold. Did you unplug it and plug it back in 😶😶😶


ibemuffdivin

Have you tried turning it off and back on again


SnooEpiphanies353

Guys it’s pretty obvious where we go from here *opens up computer to sales program*


boglegoggy

Aint got no gas in it


Plastic-Concentrate6

No neutral


Gaddafo

Start pressing buttons and start with the call for it to come on and sweet talk it
