It’s hard to really get in there but yea, they’re all right across from where those connections are which is strange

I was checking out an aquasnap that has 5 out of the 6 coils which show signs of a leak. I can’t seem to pinpoint where exactly the leaks are coming from, but the oil spots all appear around where...

I got it directly from Trane. I don't know how much a generic coil costs, but the pan was only ~$. I know the oem coil is pretty expensive, relatively speaking.



You're right, it does. I went...

Probably a dumb question, but I’m replacing the drain pan on my parents unit which is vertically mounted, and wanted to see if the pan on the right was needed for anything outside of being used on...

Oops.. meant to post this in the controls section

It’s been a while since I messed with the ucm4 boards, but I have several vavs I need to work on that we’re set up as comm3 devices. What’s the method for connecting to them on rover?

Had a fellow tech talk about bitcoin early on before it got into the 10s of thousands mark. Sold most (if not all?) early on too and made a little over 200k which he used to pay off his house. He...

I originally joined back around ~06 and have always come here for informational resources as well as entertainment. In the few times I needed assistance, you came through with no questions asked. I'm...

A bit of a bump, but I was just recently looking at this and noticed a purge and braze setting on their gauge. Are you supposed to leave it on purge for x amount of time before dropping it to braze?...

I replaced a failed OAT sensor with the ribbon style cable. I was getting the random comm issues, so I reconnected my cable, restarted the laptop, the whole thing. Went to the binding screen again...

Found an old Trane manual and thought you guys might like this :pop:

I don't work with those thermostats much, so I can't really help you on the error message but, with the wire setup that's there, it sounds like a stand alone unit and you should be able to use any...

Not that it matters but, at least the unit wasn't charred in the process.

Actually I meant 40°

Good point. I do recall someone from Trane mentioning that a while back (using entering side) but can't remember what exactly the range was (20-30*, 20-40*). I’m pushing right at the 30* mark, so if...

I was just thinking about approach on the condenser side of air cooled chillers and whether that's a value people typically log. I'm familiar with the air in/out measurement, but never heard of...

I seemed to have lost them =(



I used to take care of these hub sites for a major telecommunications company in the area and they had this exact setup throughout all their hubs. Basic...

It gets worse :X pic coming soon lol

But yea, this is one of several mechanical rooms with a similar set up..

Found this in a mechanical room next to a CW AHU with a puddle on the floor from a leaking CW valve. Oh yea, don't forget the water valve next to it

Thanks

I got a leaking CW valve at the stem and found this tag nearby. Was hoping to get some info on how to identify what valve this is to try and get a packing kit for it. Any info would be appreciated.

It looks like the cable worked. The issue was that my files were corrupted somehow.

So what are the steps to back up the files? I notice that when I create a new PCM, it automatically adds files...

Thanks all. I do have some r12 with me. Not sure when he wants me to head out there but I’ll let you all know what I find.

Ah ok thanks. It looks like I’m missing a couple of pins. Here is the setup I was given

I got a guy who wants me to check out an old coke cooler from the 50s that he states everything works, but it does not cool. I haven’t seen it yet but it looks like the pic below according to him....

I have a building with 8 of these things in there. Another building I have which had these had their old controls ripped out, so I took a spare PCM home with me to practice on. This was a functional...

I guess there's no point in asking about the big glob of foam in the 2nd pic :LOL:

I'm having issues backing up files onto my computer from a CCP (w/display). Under the "previous backups" window, it shows that a backup was done anytime I click proceed but, under the destination...

Is that a window above the toilet?

Thanks everyone, the info helped out. I heard back from jackson systems and titus, still waiting to hear back from trane. I plan on utilizing the existing controls, so damper/actuator is all I really...

So they don’t offer retrofits? Guess I’ll have to stop by there and get clarification on what they were taking about.

I sent a quote to rebuild the older style Varitrane VAVs (threaded rod, back plate, end switches, etc.) and the customer requested to also have a quote sent in for a retro fit. I called Trane to see...

Yea sorry guys. Not sure what happened. This has a bypass setup. The contactors sounded like they were chattering intermittently. I ended up tracing it to the incoming power dropping in and out. The...

Looks like the pic got rotated on my iPad. Not sure how to fix that

After using

Sorry forgot to update. The new one which came in that Monday was part number CTR02949 and it worked out. It came with the screw connections like the old Benshaws had and the existing shorting bars...

Never mind. I reread what you posted

Awesome, thanks. I'll give that a try!

Have a building with many of these ZS2P-ALC sensors and some of them have locked screens while others don't. I'm trying to unlock one of them so the occupants have control of the space temp but I'm...

Got the new shorting bars. Too big. They had the next size down in stock. Too small! Apparently, there's another cross reference sheet that he found which shows a different contactor as a...

Most of the building is occupied 24/7 and they have chilled water lieberts in their data center to top it off.

Thanks for the info

Just curious as to how this works. There are 5 AHUs here and the schedule for all of them show a start time at 12am with no stop time, 7 days a week. Does that mean there is no schedule and these are...

I can't even tell what's going on there !

I think that right there pretty much sums it up. He did it once. Let him do it again!

You did the right thing lol

I think the interlock part is the same. The issue is that the 60a has a smaller depth than the 90a. Apparently, the've had issue where the contactors "float" if you try to interlock the two different...

The existing shorting bars don’t fit the new contactors, so I’ll have to order all new ones. It’s crazy how much they cost but whatever.. my concern about the clamping force on the new contactors is...

I don’t have tech supports info so I tried getting in touch with Trane through their site and was simply told to get in touch with the local supply house. The guy from the supply house is out this...

*This is for an RTAC140, not 200*

So Trane sent me the Benshaw cross over sheet they used and I went on comfort site to see what I had then crossed referenced it to the ones he ordered for me. It...

I purchased some new contactors for an RTAC200 and from what I’ve seen, the new ones are slightly different in size so I can’t use the old mechanical interlock or aux switches (these come with...
