Need help I have a 12 years old york water chiller model:ycaj98-xv6, this chiller has (2) 8 pistons compressor model: jf843-v46. The thing is that recently we replace one of the compressors and the new one comes with 3 solenoid valves, the old one has only 2 solenoid valves from factory. Apparently 6 pistons are working full load and the other 2 with no load. We assume that the 3rd solenoid valve is fully energized. Other thing is that the compressor is working %FLA 62 constant with no step change. What should I do in this case?
