I have 2 chillers that have 4 comp. each. they have the "High IPLV Capacity Control" option installed. This starts all 4 comp. at start up to bring down chill water in a quick manor. When it starts it brings water temp down to set point which is 44. it then reduces the drives to 50 hz which is min. at 105 deg. At that point as my chill water temp. continues to drop it should turn a comp off.
All comp. continue to run until me chill water temp reaches 41.9, as my return temp is 43. At this point the chiller cycles off all 4 comp. and goes into anti recycle. then starts all 4 comp. again and continues to run all 4 and shut down all 4. Thank you for any help.
