Its a brand new hub but I will give it a try

Hey Guys

I have a site which has two BCU's, one BMTW and the other is a BMTX they both have staic IPs and are on a stand alone network not tied into the building network.I had an issue with...

Just got one of these under contract but no literature. Does anyone have any literature on these chillers? Also what is your opinion on thse compared to the Trane RTWD?

Hey guys

I am looking for an exploded view of the compressor as I have to do some testing on the slide valve. It would make it much easier if I knew what things looked like in the compressor!
...

Hey Duke

So with all the items you have listed how are they the similiar? How about the fact that trane uses a closed wheel where carrier uses an open wheel. Basically all you are saying is a...

any news on a fix? I am in a pickle, site computer crashed installed lonwatcher 3.25 and tried to import the (old) database with the same error. Anyway around this? I do not have a copy of 3.24

never had a leak their before. I believe the valve is made by a company called Sure Torque? I would look into any recalls on their valves

I have found leaks on two different occasions on the suction butterfly valve seats. You have to order the whole valve because the gasket is incorporated into the valve plate

Anyone out there have the McQuay software or know where i can get it from? IE. microtech, microtech II. Please let me know!

Hey HeatXfer

Its a new microtech II the the chiller is only about a year and a half old. Do you have the the Microtech II software?

Okay, where can I get the microtech software then?

Hey does anyone out there know where I can get the software to communicate with the new Mcquay touch screens on their chillers

service software for trane chillers with ch530/531 controls

Comm 1 is the default port that techview uses. So set up your adapter to run on Comm 1

Plugged in with rover today and the unit at first was not responding "normally" as soon as I changed some setpoints and downloaded them to the vav, the box started to work "normally" again. I guess...

Thanks for claifying. I am going back to site tommorow with the new board. But I am going to connect with rover first and comfirm the output is hooped.

Hey Mallron, thanks for the input, tracer says that "heat active: no". To clarify: if my vav is part of a vas then when I overide in rover the overide command will not work?

Thanks. Just wondering if I can manually fire the heat output triac through Rover to comfirm that the output is buggered?

Hey Guys

I am not a controls guru by any means but I am trying to learn. Today I had a service call complaing that a Trane VAV was running its electric heat with no call from Summit. I disabled...

With the time spent on trying to get the valves to hold, wouldn't it be easier just to pull the charge?

Manu1, Do you get a lot of motor burn outs on RTHA's? The only failures that I have seen are mechanically (Siezed)

In your picture what are the 2 lines in place of the oil filter? Are you using some kind of different filter? Hey drivewizard you are right they don't make them like that anymore, I would like to...

Exactly! The funny thing is the fact that it was a condenser flow issue and not a low discharge SH problem. So why am I getting this trip? I s it a CH530 glitch?

The problem is that the chiller is apparently tripping on Low discharge superheat but it is not logging in the diagnostics and giving me a condenser flow trip in the log

Thanks,

I went to site today and found that the chiller has been tripping on condenser flow according to the diagnostic history. So I reset the chiller and watched it. Within 10 seconds the...
