Abstract	This research project mainly focus on proper coordination of chiller and supporting components in order to reduce it's operating cost, improve temperature stability and improve equipment life. Control algorithm measures critical parameters and adjust variable outputs to optimize number of running compressors, chill water pumps and air handler units with improved performance. Case study was done at fashion lace knitting facility at Biyagama, Sri Lanka. Temperature stability is a one of the basic requirement of this warp knitting facility. Implemented PLC base controller is compatible to handle any type of high and medium capacity multi compressor chiller system. It has remote critical data and impotent parameter display. System can be control through remote logging and there is history data table and graphs. This controller eliminates KVA peaks which generated during chiller starting and chill water pumps starting period. Further electricity cost further reduces by 5% through three band tariff system.
