    It shouldn't need to be cold outside for this problem. It may have been a coincidence.

    Unless it runs 24/7 and it only stops a compressor on a cold night, when the load is light and it drops chill water below setpoint. Don't doubt yourself now R123! I would eliminate, or verify, this possibility next.

    I had a similar problem with a RTAA do everything that I found in the past in this forum fails
    Compressor to testing all the symptoms had appeared to be lip problems put the kit to return the slide valve and the problem was not corrected

    The problem I have is I am doing a study temperature of thermal loads and flows
    I have three units and only RTAA200 the systems are operating correctly systems number 1 number two in the last 2 years have been problems with oil and I replaced 2

    In fact a new one in place a system does not operate correctly 2 and still had problems with the fall 199
    Remove compressor system 1 and place the new and it operates correctly

    So we are doing this study

    I forgot to mention that the water pressure drop was correct as requested by the manual
    is the reason why we do not have cash flow problems

    Ok I shut this turkey down overnight several times since it has finally got cold here. I cannot make it act up on first start in the morning. However, if I let it run overnight in cold weather the very next morning the damm thing will have either high pressure cutout or code 198/199 oil flow codes.

    Someone before me already performed the SB-4 bulletin for the load unload solenoid re-route on both circuits

    From all of the discussion here the problem is that she's randomly started loaded on first start during the night or early morning at some point.

    I performed every step in the slide valve troubleshooting bulletin multiple times and everything passes with flying colors I cant make it ever act up.

    Based off the randomly starting loaded where do I go from here what the heck do I rebuild replace etc to fix it when I cant ever make it act up when I am there to catch it. And again it has had the load unload solenoid re-route done in the past. Thanks for all of the help guys I'm at my wits end on this stinking thing.

    Sounds like you have a condition in the condenser fan staging that's possibly getting you right to the edge of tripping, but only going past that point every once in a while. Pull up a bucket, put your winter coat on, and watch it to see what happens. You can probably manually cycle it and watch the dp across the filter during all aspects of operation to determine when you're getting to the trip point and reconcile the cause with the conditions. Nobody said this would be easy...

    BTW, welcome to the SEC...........

    Maybe he could install a fan cycle switch on each circuit temporarily to fire a set of fans and get a jump start on the chiller controls bringing the fans on . At least just to see if the alarms go away for a week or two. Sounds like that we have a theory of what's going on but this would throw that doubt out.

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.
