 "summary": "YVWA chillers connect to a BAS through the SC-EQ communication card on BACnet MS/TP (or Modbus RTU / N2). The BAS can start/stop the unit, write the chilled liquid setpoint, current limit and heating setpoint, and switch between chiller and heat pump mode. Read-only points cover chilled and condenser liquid temperatures, per-system pressures, % FLA, hours and starts, VSD values, valve positions and multistate operational and fault codes per system.",
