 "summary": "YVAA, YVFA and YAGK 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 chiller, write the cooling setpoint, current limit and sound limit, and inhibit the free cooling valve. Read-only points cover chilled liquid and ambient temperatures, per-system pressures, temperatures, % FLA, kW and lockouts, VSD values, condenser fan data, free cooling (YVFA) values, and multistate operational, fault and warning codes per system. This is the standard list; separate lists exist for the YT3 panel and the YVAA Style B.",

  "Access is inferred: the sheet has no read/write column. The remote block (AV 1, AV 2, AV 3, BV 1, BV 2, BV 3, BV 4) is treated as commandable and MV 65001 as writable; everything else as read-only.",
  "AV 37 and AV 42 mean subcooling on microchannel condensers and evaporator level on round-tube condensers; they are merged into one row each.",
  "Free cooling points (BV 35, BV 40-41, AV 48-54, MV 12, AV 450) only apply to YVFA units with free cooling enabled; condenser fan points depend on the fan control type.",
  "Operational and fault code MVs (MV 1-4) use the Status Codes tables + 1, as the sheet says to add 1 for BACnet MSV values; the AV copies (AV 501-504) and the warning code AVs (AV 417-418) use the raw code. This list has no warning code MVs.",
  "Multistate states with their own enum in the points table (Units, system state, free cooling mode) are shown as printed, from 0. BACnet multistate values start at 1, so the device may report the printed number + 1; confirm by discovery.",
  "Units shown are the IP units; with MV 65001 set to SI the card reports °C, bar and so on. Spare and reserved objects are left out."
