 "summary": "The Technologic Constant Speed Pump Controller runs a multi-pump constant speed system and has a BACnet MS/TP interface on RS-485 (B-ASC profile). Its PICS lists 60 objects: pump state codes and process readings as analog inputs, six process commands as analog outputs, failure flags as binary inputs, and start/stop, reset and alternation as binary outputs. Which process readings and commands are used depends on how the controller is set up.",

  "The PICS prints PSI as the unit of every analog output, including the flow and temperature commands, and lists Amps and Horsepower without units; check units on site.",
