I understood correctly your question and my answer is the same, those are diagnostics that affect that specific circuit, look on the historical diagnostics to confirm, and no there is no...

You are missing some information here, both diagnostics "low ref temp" and "HP trip are latching diagnostics but only affects that specific circuit unless you have the same diagnostic on both...

What is the diagnostics you get? when you said the "loop" do you mean refrigeration circuit?

What a bunch of crap, not having the proper clearance could cause a premature failure or shorten the life expectancy of these units and yes I have seen many units nor performing well due to people...

I wish all contactors had the mentality of bwalley, I respect and applaud your way of thinking!! keep it that way.

Check for non-condensables and make sure the condenser coils are clean, what is the subcooling do you have the model or serial? subcoolong on these units goes based on the tonnage and efficiency no...

We have seen some issues with those valves, the important part is that if you need to replace it make sure to torque it in star pattern @ 60ft/lb. I would recommend to start @ 30 then increase to 45...

Also confirmed to work is this: http://www.byterunner.com/byterunner/product_name=Y-105/user-id=/password=/exchange=/exact_match=exact the price is nice too.

If you do a notfication or recall you will have every single office and customers calling to do a "pro-active" change out and wanting the factory to pay for everything, some times is better to do a...

Apply discharge pressure directly to the piston chamber (Schrader on the front) , and monitor RLA, if the RLA increases you have a problem with the load solenoid if the RLA never increases more...

This was a compressor burnout replacement and we use the oil cleaning kit, which is a rack of filters to celan the system. :cool:

Measuring oil on a RTHB unit is almost impossible as the charging port is elevated 3" which is what the IOM manual calls to be the level, oil on these chillers moves all over the system and that is...

Check the discharge temp sensor as well as the condenser pressure transducer, make sure they are reading correct, you will need to strap s thermometer next to the discharge sensor and compare the...

I believe you have a problem with the female unloader, that is the solenoid on the left hand side looking the compressor from the discharge end, when the chiller runs with low load the compressor...

OK, back to the original question, if your computer doesn't have serial port you will need to buy a USB to serial adapter but just any adapter Trane Pueblo is recommending the following, go to the...

where I live there is a company that represents 4 mayor brands, at least on paper because when you call them they support pretty much just the brand that gives them the most incentives not the best...

a good recognized brand is important but the installer is even more important, a good brand unit installed by a guy who doesn't have a clue of what he's doing will trash the equipment and you will...

What is the circuit tonnage? and the chiller serial number? There was a problem with the EXV motor torque on circuits with 2 compressors where if the chiller stays on line for long periods of time...

If the chiller is A77 means is limited by low ref temp on the evap, and that could be caused by several things: what is the chilled water SP? what is the low ref temp cutout SP? what is the...

Try 1111 (supervisor) and 2222 (operator), if these doesn't work call Trane for help.

Pueblo produces lot more products than La Crosse, produces more money and the cost of warranty expense is also lower than LaCrosse built units the truth is Pueblo has been looked as the young brother...

You are going to spend a bunch of money, and it looks like you are doing your homework finding out the pro's and con's of each brand, if you talk with every manufacturer they will tell you why this...

Technically speaking the check valve(s) should avoid the compressor from spinning backwards, as mention before if the compressor there is not enough force to pin the compressor backwards enough to...

If both chillers are tripping on phase unbalance have you checked what is the real unbalance? This controller is design to trip when the curretn unbalance is above 25% are you sure they are not doing...

The chances of being successful replacing bearings and seals and leave the compressor at factory specs are slim, the clearance between the rotors and discharge face is 0.0024" and something similar...
