Would you agree if I said that these inverter systems were made to help the salesman not the homeowner or technicians?
100%. Would you agree that you have to have degree in engineering to operate thermostat. KISS .
@@andrzejhajder6405 unreal.
You’re saying passenger jets aren’t reliable?
As a trane dealer. Wire nuts are fine on these units as long as there is dielectric grease in the connections. As for those saying not to call tech support, bad idea. You can not just warranty parts on this unit. Purchase of that inverter board prior to talking to tech support is $3000 out of your pocket. Purchasing that board prior to talking to tech support, they will refuse warranty(if applied). Tech support has to approve your diagnosis to allow you to warranty. Also, to check your dc voltage on this unit, use the 2 voltage pins on the bottom right of the inverter. Any other place will not be accepted by tech support.
Makes sense to me. Corrosion can happen to any connection on any type or brand of unit. A surge protector once again is a good idea on any unit.
These things are the plasma TV,s of the HVAC world . Unless Train comes up with a economical solution for these type of units, their customers will be one and done with Train , and rightfully so .
Johnathon is correct. I work for American standard dealer. TRANE and AMS is the same. Same tech support. Call either and they will help. You must have diagnose from tech support to warranty. Also please ensure com wires are shielded. We install a lot of these units. There is also a much better diagnostic book for these units. You must attend a class to get the book but you may be able to find one online.
Not only that they want you to have taken classes on this unit before you can even work on it. But this is been years ago everybody should know how to do these by now. I’ve diagnosed installed nearly 100 of these and helped install them. I had to go help others. 😢🎉Some days are better than others.😅
We have a ton of these on the ocean in South Florida and it’s not good. It says do not put them and they are avoiding the warranty on a bunch of these inverters lol.😅❤
Sounds like the inverter board in the odu is kinda oscillating. Probably bad caps internal to the switching power supply internally in the inverter. Probably noisy enough on the bus to foul up communications
Had to replace drives on four different units for customer because of brown out and they didn't install surge protection, sequence to reset system, power off both indoor and outdoor, power indoor first, then power outdoor, will clear communication alert, also typically three contrlol conductors
Not a fan of these communicating systems. I like the Bosch units that don't require one and you can read all the diagnostics at the condenser unit. All these proprietary t-stats feels like the manufacturer effectively preventing the customer from calling a non-Trane contractor. Ted is a big fan but he knows them cold. Thanks for the video.
I'm a big fan of Trane. I make a bunch of money working on Trane. No way I'll sell one though. This one apartment I work on has a bunch of Trane package units and every one has had a major failure. Compressors, a bunch of txvs, blower boards. Can't blame that on installers.
WoW Curtis,these new systems are far to complicated, my origional reverse cycle A/C system was a Australian built " Email Air " it was installed in 1986 and replaced with a new split Daikin reverse cycle.. My Email Air was replacrd in 2020 due to the outside metal cabinet starting to rust out and even then it still run like new, heating and cooling, in that time it was service/checked over only a few times. 👍 Au
Electronics guy here. The noise is most likelly from the powersupply section of the main controller. It is caused by the magnetic field in the inductors causing things to vibrate. It can also becaused by the magnetic field that cause heating in the core, which cause some dillatation, which is movement, which is noise. This is usually not normal and often a sign of something that is or has failed..
The pulsing seems to indicate that the regulator is working in discontinuous mode, which should not happen. If it is the case, the output voltage can be unstable and very noisy. That make microcontrollers very unhappy.
As for wirenut, this is a low bitrate bus. Wirenuts are fine for those. If wirenut is an issue, then it mean you would require to crimp some terminals and connector, not use screw terminals. And most likelly require to use twisted pair, and not untwist anything. That said, it is a good practice to avoid them when possible.
RS485 or simmilar can work on very bad wiring condition. There is a reason why they use that in industrial machine, with wires close to high power motor wires. It is a pretty much rugged system.
For RMA, you are required to get an authorisation for almost every single manufacturers. Any warranty work need to be preaproved. The manufacturer will ensure that the repair guy is authorised and know what he is doing. A manufacturer and and does limit who can repair stuff, and that vary from industry to industry, car being the most open field. Failure to request the authorisation prior to the repair can (and will) void (part or all of) the warranty on the device!
Manufacturer usually encourage the authorised repair technicians to call them when they have anything that they are unsure about.
Call Trane Tech support to confirm diagnosis. These high efficiency smart systems can be troublesome. Hopefully new enough to have some part warranties on it.
He did call.
You have to take a class on these before they tell you anything. And be on the list of contractors allowed to work on them.
@jthonn yeah saw it at end after my comment.
@@adampajcz8719 Exactly !
@adampajcz8719 that's what I was thinking. However this one isn't in warranty, they might see $ signs.
Maybe check the three low voltage wire connections at the air handler. Maybe the D wire at the air handler is not making a good connection to the outdoor unit or maybe there is a splice between the outdoor unit and the air handler or something. I am looking forward to hearing what the fix was. Good luck Curtis
me too
There's a lot to be said for the reliability of a simple, lower-tech solution to heating and cooling. I'd gladly trade the perceived high efficiency and rich feature set of these high-dollar, highly complex pieces of equipment for a simple, traditional air-to-air heat pump.
Take care and God Bless.
They need to learn the KISS method. Keep It simple stupid. Some engineers sitting behind a desk trying to prove they have a job. Not that all engineers are bad. The ones on Southern Railroad are pretty cool.
What happens during the next supply chain disruption?
@@russingersoll5761 You'll have to wait for replacement parts for a very long time. Your customer will sue you unless you fix the unit ASAP.
Constant torque X13 motors and constant air flow motors are Sh!tty motors.
@@russingersoll5761 Or WORSE TRANE 's Rep. " Oh Sorry that model had been discontinued and we no longer carry the parts "
CDA is just a dumb monitor. Everything communicates by RS-485 twisted serial data link wire pair. Fact that CDA does not respond, and thermostat cannot communicate with outside unit means either a disruption like a shorted data line wire pair or something wrong with outside computer board.
Strange thing is outside compressor is running which I would think it should be dead if communications with air handler is lost. There must be coordination between air handler and outside unit on a variable speed unit. Having the outside unit running on its own would not be a good sign for condition of outside computer board. Outside unit should not be running if it does not receive control commands from air handler.
When units first power up there is a communication check between all devices. If there is a comm failure the outside unit should remain inactive.
Thermostat controls air handler and air handler controls outside unit. Thermostat can receive pass-through diagnostics from outside unit but does not directly control operation of outside unit.
The copper tubing loop on back of module is refrigerant flow heat sinking for three phase inverter that runs compressor. Should be clamping screws on back of module to free module from cooling tubes to allowing module to slide out upward from behind copper tubing.
Really scary thing is customer says her electric bill was abnormally high. That may mean outside unit has been running for over a month straight non-stop.
I don't think the compressor is running, it sounds to me like the other unit next to it is what's running.
Probably running the heat strips to make power bill go up.
So this could be a rat chewed wire. Is he going to replace the module?
Funny, when I open up a panel and see an inverter I usually don't say "ohhhhhhh." It's usually Ohhhhhh @#$%^&*(. !!!!
some real help:
The voltage between the data high and common, or data low and common should be 2 & 4 volts DC.
A broken/open thermostat wire to an individual component will only influence that component. If a data line breaks to the outdoor unit, Link will show the outdoor unit is offline and generate a 94.00 alarm for a comm failure. Since the outdoor unit is offline, disconnect the wire connector at the outdoor unit and look for voltages. There is no voltage between white DH and common. If the indoor init is powered up with proper voltage, then isolation troubleshooting has confirmed a broken white wire (or failed connector).
A short on the data high DH will cause the communication bus to fail. Short between DH and DL, short between either DH to DL or R. A short between DL and C may allow system operation; but have intermittent communication errors.
There is a short somewhere, board may not need replacement
Thanks
Where do u learn all this?
Nice work Curtis. Trane units are getting way too complicated.
Just another necessity appliance created, so that it can be shut down 'From the Sky' if 'The Powers That Be' wants to.
worst systems to work on 🥴
@@butlerstouchHVAC the systems were made to help the salesman. Not the homeowner, not the technicians.😮
So are Carrier and Lennox
You got to check those low voltage wires. I believe you have to hold the buttons on the cda for 10 secs to access the menu. I would say if you got no com LEDs on the inverter and it's getting proper dcv then I would call Trane for authorization to replace it. I've had those com errors from rusted wire nuts to a buried splice in the dirt.
no shit, thanks for the info
Need to tun a drive test and contact Trane tech support to get authorization for a board. That’s the only way you can get a board
Finally! I work for a trane dealer company and I wish i worked on these more , so nice to have a troubleshooting vid
Just because something like this can built doesn't mean it should.
Yep, welcome to inverters. That's mainly what i work on, 90 percent of the issues I see with units are the inverter pcb and here in Australia parts are very expensive
always check the wiring between the tstat to AH and AH to condensor first with communicating faults
All new stuff is junk!!!! Help us oh lord!!! It all started when we went from 2 refrigerants to 22 lol!!
But the smart communicating thermostat has diagnostics to pinpoint the problem. Except when it cant communicate with the inverter. Then its 1-800- Im stuck
Communicating systems don't like wire nuts, they need a straight connection and need to be away from high voltage wire due to impedance. Also, inverters need a surge protector or this can and will happen as well. I think the board is the answer though. These systems suck.
I second this. I use wago’s when I install these. There’s a reason the zone boards come with a handful of them from the factory. Running shielded wires and keeping them away from line voltage wires is paramount. Also, any inverter system should DEFINITELY have a surge protector at the disconnect or the panel. Could be something as simple as that. I’ve seen it before.
I believe you guys, but this thing was evidently working.@@zacharyloewke6366
Most over-engineered units regardless of brand and model are usually a problem for expensive repairs and maintenance!
Would you guys agree if I said that these systems were made to help the salesman and not the homeowner or the technicians?
Sun is always out when you’re working on ac. Always shady working on heat😂
Yes. Start with the wiring and connections. Tech support will most definitely have you change a cda before they will authorize an inverter drive replacement. Like the other comments said, those aren't cheap. I've worked a lot with the AS side discharge communicating systems. They can be picky to dial in, but run great after. Very precise on the charge. When it hits 100°, 5-10oz extra on an 8lb factory charge system makes all the difference on whether the system will run or not. I try to dial them in on startup, but sometimes its so hard to simulate those hotter days. I live in eastern Washington and we definitely see temps over 100°
On the XV with comm errs first check 16v at j4 unplugged that proves the AFC is communicating which is likely bc the stat shows errors, plug j4 in and voltage on the back should drop to 12v if com to the drive is good… the CDA is controlled by the drive. If you can’t get CDA to do anything you likely have a bad drive but you’d need to run a drive test from the CDA to confirm. With what you have call trane and get a drive authorization. And do not lose the personality module in the process.
But they are super easy to replace, just did one Monday.
I hated running into communicating inverter systems when I worked with an HVAC company. So complicated and many things to cause failures
Exactly ! You certainly can work and figure out what wrong with that system, it's certainly not rocket sciences BUT you have to spend times to study that system and for HOW LONG? Is it worth it ? and chances are you probably won't run into that system again because I believe there're not many of them in your service area.
oh gawd and that Personality Module dont lose it off the old board you need it to plug into new board if it comes to that
but those boards cost 1.3k under warranty, if trane approves after you ship it to them and they test it
Exactly what you need in a time when supply chain disruptions are highly likely. If it won't hold up for five years and is obscenely difficult to troubleshoot and expensive to repair and the parts aren't common, is it really progress?
I hear you. Don't try to make sense out of it, you will go nuts.
That’s why I don’t sell these units. I hate how hard and expensive it is to fix.
The price is the biggest problem. 3k for the inverter board is outrageous. If the board was 100 bucks, no big deal.@@jesrovalenzuela1346
Do a drive test, but if your cda won't give you access, to run a drive test, you can try a new cda and see if that would get access into that drive
Also, confirm you have 16vdc coming from these two wires going to your indoor unit
for heaven's sake
As someone once said to me, "more funny, more money"
Give me a contactor, capacitor, and a defrost board. Heck. I keep them on the truck and they are reliable.

A gift that keeps on giving 💩😂
@@chris76-01 if only I could be there during the sale 🤥
An inverter compressor is actually pretty simple. It's a 3 phase motor with a variable frequency driver. (Inverter). This thing is extremely overcomplicated and is designed to make Trane a bunch of money through replacement parts.
No
@@sprockkets yes
Sounds like train come up with a money racket just got have the best one they said lol
Make sure the floatswitch is breaking the proper wires at the airhandler too. The diagnostic board is doa too
Or a shorted communication wire.
I would say call train, tech-support and talk to them but they probably won’t help you because that’s why most manufactures that make their product are they don’t want to talk to an outside tech-support because they want the money themselves. It’s a shame that it’s that way in our world that’s how they try to trap you to a specific unit which is crazy.
He did call them.
Train tech support is great for someone who is not familiar with their communicating systems. Or even a trained AS technician.
No thanks. I'm perfectly happy with my 2018 simple tried and true, easy to fix, reliable single speed everything, non cap in a box unit. Heats and cools beautifully here in the NC foothills. Power bill is great. Save your money and insulate instead. Insulation is truly the biggest bang for your buck. My unit runs maybe 15 min per hour when its 25* outside at night. Strips run about 30 seconds at the end till satisfied. Save 1000's, insulate instead.
Exactly. I have one customer who's power bill is lower than any other customer I have and she has an old 10 seer janitrol. She spent her money on insulation. Trying to squeeze more out of a heat pump for thousands of dollars is dumb.
@@Bryan-Hensley for sure, $3000 for a replacement inverter board will buy a hell of a lot of insulation. Sadly the lady in the video, for some reason, is not under warranty...smh.
@@steveoh9838 I don't understand why? Is this thing over ten years old.
@@steveoh9838 since it's not under warranty, I'd be taking it apart and trying to find what is wrong. Or take it to an electronic repair shop. It might just be some bad capacitors or transistors..
@@Bryan-Hensley Janitrol ? Lol mine is Concord installed in 05 still kicking !
I called trane tech support one time about one of these. The guy on the phone gave me an attitude because I didn't take a course on this unit. So much for support
It's not very smart to avoid classes on these complex units; you need to sign up and take the class. When I was a dealer for American Standard I took courses on it as well as Trane products; some models were quite different! Retired now!
@@bobboscarato1313 I would love to take a course on these units.

Please do a follow up on this. Thanks!
Will do!
Yes please I'm an apprentice and these systems confuse the hell out of me
common mode voltage on rs485 communicating systems ranges from -7V to +12V DC. The noise you are hearing is a broken package on the bridge, FSD, or the IPM on the inverter board. Think of it in terms of its a switching mode power supply, if you are audibly hearing the switching, then you have a broken case insulator around said switching device.
Overkill in my opinion rather have a simple and reliable system 😊
Amen to that. Thing is, that is what they have and he needs to learn how to fix it.
I'm sticking with a dumb thermostat and dumb HVAC unit. Less efficient, more reliable and long run cheaper.
You know Jeff, I looked up the difference in seers and all of that and how much money you save, and it is not worth it at all. So they will never be able to sell me on efficiency. I do like my smart t-stat though, maybe I just got a good one. It's a Honeywell that I put in like 8 or 10 years ago. It was on sale for about 100 bucks. I can control it with my phone, which comes in handy when you are away. The one I had was so old, and used batteries. I did have to utilize another wire going to the t-stat and hooked it up on the ( c) wire to power it. No more batteries. @@jeffsomers28

Down here in south florida we had to replace the low voltage wires on those systems between the a/h and c/u, especially if the line set was ran under the slab which most of them down here are, the chase gets filled with water and the low voltage sits in the water and cause all sorts of comm problems.
myself, i'd kill the control power and reset everything before moving on. often, especially out in the county, power glitches cause communication problems.
The communicating type systems they are touchy about corroded wiring in the wirenuts so it could be corroded wires in the wirenuts for the com wires if they are not the dielectric grease kind of wirenuts. One thing you might try that is free is to power off both the indoor unit and outdoor unit, clean the com wire connections. Then power on the outdoor unit first, after about a minute for booting, power on the indoor unit. Wait 5 or so minutes for everything to boot and establish communications and see if the units start communicating and run normally. There are brands that require the outdoor unit to be powered on first to setup initial communications or if coms has been lost due to a fault to set up and establish the coms again.
That noise totally sounds like bad capacitors to me.
126. Cannot find condenser / heat pump most likely communication issue. Power off may be through a breaker or line voltage somewhere. My first guess we’ll see what happens from here.
Apparently UA-cam will not allow you to post in another video link.
Look up UA-cam video title "No AC on Communicating Trane XV18 Heat Pump" from 3 years ago. Sounds like identical issue.
To be continued 👍👍👍
Complaining about electric bill and they have it set at 75 for heat we run 68 for heat
68 for me too,75 is crazy warm,I'd be burning up
It's not going to make much difference. It would be equivalent to a day that's an average of 31 degree vs a 38 degree day. Very little difference at all.
Often wondered who in the heck could afford a TRANE. 🤔 Rarely see Residential Units from that Company. 🤔
IKR, my neighbor got one couple of years ago, 4 ton I think. I looked it up and it was on the high side of 12k. I was quoted 6k for a 4 ton Heil. I guess I need to make that move.
Plenty here in New Jersey. I have one but it’s not a communicating one, just a 2 stage condenser with a 2 stage gas furnace

Lawsuit for sure!
Nah, I'd tell this service call to call the elite Trane companies (that charges $180 per service call) and I would go do those other 3 or 4 calls instead.
@@jthonnif you aren't a special trained Trane tech for these systems, Trane won't warranty the parts.
You might get Ted Cook's opinion on this one, but I have to wonder if this customer was oversold an expensive, unreliable, tough-to-repair, piece of overly complex fecal material so some salesman could buy a boat.
Is there a float switch wired into the com wires in the attic as opposed to the jumper on the board? I’ve seen this done on communicating equipment and cause it to throw codes.
Board/Drive definitely doesn’t sound right.
That sounds like a whiny VFD
No way I would even touch this without Trane Factory Tech Support…you need someone to walk you through this. Unless I’m wrong, you removed the condenser unit permanently from the equipment list on the thermostat. Most Trane units have a 10 year parts and labor warranty too. Might just hand it over to a Trane dealer for repair on this job 🤷♂️
I am not worthy of making comments on this one but from the video, you disconnected the two conductor communication connector from the condenser before you went back inside to the Thermostat with no communication. Sometimes videos don't show everything. You are the Sharpest Tech Guy I have ever seen! And I'm looking forward to your solution. It would be interesting to see the waveform on the variable Motor Driver! Thanks for the Mystery!!! 🧐 🪛 😉
Just need to replace the AA batteries in the control unit. :)
Definitely the drive. I’ve never heard one make that noise. That 12vdc you read at the j4 plug was because the air handler was still hooked up. Unplug j4 and test across common and data at the board and see what it’s putting out. Also check vdc at the black and red test points at the bottom of the drive and see what you have there.
Did you try cycling power off and back on to both units, you have to turn on the outdoor first and ahu second. We get calls on these after preventative service. Maintenance techs turn off power to outdoor unit to wash coils.when they power back up, the ahu doesn’t see outdoor and you get a comm error
11:18 Pull the disconnect and rest it!.
HVAC systems today are catching up to 1980s car computer technology. It’s a bumpy road but eventually will get sorted. In the meantime we just turned away a “top of the line” Trane/Ameri Standard and installed a new, reliable Coleman 2-stage with variable speed AH. Simple happy life.
I haven't a clue. They are making things too techie or too computerised now days. It may be something simple. Communication error, yeah OK. I think you are on the right track. Wait till the geckos get to that one. Last comments someone ask what was the best units, I said I use to holler Trane, but now days I'm not too sure.
Instead of having to go back and forth between the outdoor equipment and that "thermostat" (which is really more of a computer terminal) Trane should make a way for you to "talk" to the outdoor unit by using Trane software on your tablet / connected to the outdoor systm by USB or maybe even bluetooth. Maybe even a way to connect that outdoor equipment to Trans support via the Internet to have them check it out.
You are probably right, good grief.
@@jthonn When you have a complex installation like this zone system, you are going to see complex equipment like this sold to homeowners; this system seems like overkill ( or OVERSELL! ) to me in this somewhat modest residential setting. Some huge fancy mansion, or a high-rise / commercial building, yes it would seem appropriate there. But this residential setup looks oversold and overcooked. But maybe this is the way systems are going to go as time and technology advances - if so, then the tools and the training for the average residential HVAC tech will need to advance right along with them. Curtis did a good job here trying to look into this problem, but he needs better computer tools to talk to the system and ask it how it's doing, what it's problem is..... 😎😎
@@billmilosz 😎😎🤑🤔😱
Right but in the end you increase its complexity!
The new Trane inverter link system allows exactly what you described kinda cool you can sit in your van and watch every parameter of the system pressures temperatures voltages it's pretty cool
Likely an inverter board problem. I think the noise is it attempting to run the compressor. Although, you might want to confirm the compressor is connected and working OK and not locked up. Electronic items tend to fail in the power section.
Embrace the technology as Steve Lav would say. I think it needs fixing the same way you fixed your leak detector. KISS
Check for warranty
I'm a lot like you. However this is how you can really damage your reputation. You probably shouldn't practice on a customer's unit. If you diagnose it wrong, charge them thousands in parts, then it fails again in a little while, they'll bash you like crazy. I've been down this road and it was a Trane. It wasn't an inverter system but electronic expansion valve. The system went through 3 compressor in less than 4 years.
Isn't that unit under warranty? Get a Trane tech out there to fix it!
No, it’s not
@@HVACGUYOMG. I think those boards are about 3 grand.
I think you should replace the board and the cda, cause if there’s communication vdc and 240v to board and nothings happening maybe it’s the board

Don’t need red/24V just common/b and D/data, (24V is for power shedding). Not to hard to troubleshoot due to the fact the thermostat/control tells you where to start looking. Also it’s a pain in the A** trying to get that inverter drive board got to go through tech supports steps to condemn that board before they can warranty it out. Only seen one of those go bad they are actually built robust it went bad due to a rat making a nest out of the control panel and shortening it out.
Communicating it's like it use by a electronic contacter for inverter units and cda means Communicating device assist it's locating inside the control board on a outdoor unit and the sound inside the board is not good so that board needs to be replaced.
Reboot everything first!
more parts more problems
At 1:00 the thermostat looked like it took hit , maybe moving furniture . Hoped you checked the back side ,was thinking a connection half off,
It sounds like a switching supply in current limit .
Could it be a short on a communication line ?
If it's a short or voltage from something back feeding it could kill a new inverter .
( Don't ignore ground loops ) .
So **TEST** before changing the controller .
It should be 100% idiot proof but some are on a higher pay grade .
Also some design products !
shut off power to both units and see if the problem comes back. if that doesn't work give the job to a train dealer and move on ur losing money and time.
Yeah imagine purchasing the 2 to 3 grand board and something else is wrong and damages it.
I hate communicating systems... especially from Trane. Overpriced, and a royal pain to work with.
They are trying their best to close their market. Only Trane parts. Only specific Trane service techs.
All this while the old faithful beside it heats away 😂
Are these unit DC not 24 volts??
Reminds me of Tommy Boy…”I can take a dump in a box and mark it guaranteed, then you’ll have a guaranteed piece of sh!t.” Lol
Hi bro from west Alabama
Reboot it by power cycling. That worked with my computer.
Over engineered system. This system was more then likely sold by a sales person trying to make some commission. Good troubleshooting so far Curtis.
Check if you have 12vdc coming from the air handler
if they're going to put all this stuff on one why don't they just have a port like a car dose so you have to try an look at somthing that smal just plug in an read
Don't know if you have ever worked in a coastal environment, like North Carolina outbanks, but these systems last about a year. Salt sand wind, eat them up.
That is why after 25 years in the field I'm looking for security job or janitor.
Exactly ! You certainly can work and figure out what wrong with that system, it's certainly not rocket sciences BUT you have to spend times to study that system and for HOW LONG? Is it worth it ? and chances are you probably won't run into that system again because I believe there're not many of them in your service area.
Good video Curtis, is it under warranty ?
No
That's a shame, I have a XV20i, glad I got the 10 year warranty, I worked for a Trane dealer and got a smoking deal on the system.
Those inverter boards are not cheap.
Tell us what those boards cost if you find out .
About 3 grand from what I've heard
If its not communicating its most likely a low voltage break as far as that noise im not sure i haven't herd that on them yet if you have to replace that board you should sell them a normal one...😂because its expensive....
Was there a replacement video on this unit?
I’ve worked on those before. Weren’t there supposed to be 3 wires for communication instead of 2
Hi Curtis may be I misunderstood you but at 4:58 when you checking out the communication wire connections/splices I saw the RED wire not connected/cut .I believe the red wire needs to be connected to bring the 24vac from the indoor AH to the OD condenser ? You showed us only 2 wires BLUE and BROWN ?
RED 24v hot
Blue 24V common
Brown Data
I didn't see the red connected WHY ?
You only wire the red wire if you need to load shed, does not need 24 volts from the air handler
@@numbnut257 Sorry "shed" ? meaning ? English my second language! thanks.
States like California require load shedding due to high electricity demand. Load shedding (loadshedding) is a way to distribute demand for electrical power across multiple power sources. Load shedding is used to relieve stress on a primary energy source when demand for electricity is greater than the primary power source can supply.
Per American Standard and Trane 24v to ODU only needs to be hooked up if load shed is required.
These new Trane units have completely gone too far with making a simple heat and cool system very difficult for the customer and the technician. It comes down to cost. Trane charges more for this unless technology costing the customer more money for the unit and more money for service repair. I wouldn't have it. Just give me a basic unit because all I want is to warm in winter and cool in summer.😊
Another reason not to install communicating inverter systems. The manufacture's are using the contractors and the customers for their research and development. Lead the customers away from these systems.
Trane is awesome ain’t they!
Trane inverters are awesome. They cost as much as a new system almost.
I from northeast North Carolina. We have a lot of Heat Pumps.
Know when to walk away and know when to run! Its a good time to walk away.
It's a learning experience.@@bamatractor
Sorry mam your electricity bill is high because you want your house 75 degrees so yes it will run a lot try putting it at 70 and we’re some clothes or go outside for a bit come back in
Doesn't make much difference at all. It's equivalent to a 31 degree day vs a 36 degree day. 5 degrees isn't going to be noticeable much at all.
