 "summary": "This SC-EQ list covers the YORK scroll product family: air- and water-cooled scroll chillers, heat pumps and condensing units. The SC-EQ card serves BACnet MS/TP (or Modbus RTU / N2). The BAS can start/stop the unit or each system, write setpoints, range, load limit stage and heat pump mode. Several objects change meaning with the unit type (condensing unit, heat pump, YCWL, EEV, refrigerant), so the sheet prints more than one row for them.",

  "System 2 points only report on two-system units; EEV, heat pump and condensing unit points only on those units.",
  "Operational and fault code MVs (MV 1-4) are the printed code + 1, as the sheet says to add 1 for BACnet MSV values; the AV copies (AV 501-504) carry the raw code. MV 10 / AV 505 are shown as printed, from 0; the card may report the printed number + 1.",
