Having trouble with a rebuilt Tecogen 50 Ton engine driven chiller. Since we rebuilt the chiller (engine and compressor) ourselves (the unit is just over 10 years old) Tecogen will not assist in solving our troubles. With a rebuilt compressor and engine the controls tend to shut off the unit after an hour or so. To a lesser extent the unit had these issues before being rebuilt but seem more frequent now. Is there anyone out there who could devise a common sense control system out there? We would love to have ours reprogrammed or booted. We're located in Indiana.
