Been having problems with a RTAA 100 ton chiller, two circuits. I replaced circuit B compressor about a month ago and it has been running fine until the past week. We have had 100F ambient air also for the past month down here in Texas. Circuit A is fine. On install, I weighed charge in to 100lbs. Unit calls for 98lbs but I added a suction line drier. It is a remanufactured compressor and was shipped with no oil. I follow directions and put about 2 pints in suction cavity of compressor and primed oil filter two hand pumps of oil. I also put in fresh three gallons of Trane 15 oil. I previously cleaned entire system because of burnout. After changing drier cores out multiple times I checked for acid and system was clean so I took suction drier cores out and button her up. I added two extra pounds of freon because of the extra piping. So it has been running fine for a month and that was the history of it. Now it is going off on winding temp. I have checked all condenser fans, cleaned condensers very good, checked for restrictions on LL drier all good. Got a clear sight glass, around 5-6 superheat and 18-19 subcool. I have a normal suction pressure, about 90psi with 65F water leaving. Head pressure is a little high, around 360. I cannot seem to find anything about the compressor winding stats. The cover of the panel on top of compressor shows three t-stats, I have mine hooked up from W to BT. What are the three for? Can I switch them around if maybe one is faulty? I'm open to ideas, thanks!
