 "summary": "The ElectroVap MC (ELMC) is an electrode-boiler steam humidifier whose V3 controller talks Modbus RTU or BACnet MS/TP on RS485. The BACnet map gives contactor, level, valve and relay states as Binary Inputs, a start/stop Binary Output, current, run status, error code and steam output as Analog Inputs, and setpoint, demand, capacity limit and drain settings as Analog Values.",

  "The manual's table has no read/write column; access is inferred from the Modbus register area (coils and holding registers writable).",
  "The description column is used as the object name. The English print labels the Analog Input class \"Have\" (a mistranslation); the hex IDs confirm Analog Input.",
  "Rows marked \"Not used\" (BV 1, AV 7, AV 8) are left out.",
  "Option relays 3 and 4 are printed as BV 1 and BV 2 with the same hex IDs as the BV 1 and BV 2 rows above them, so their real instances are unclear; they are left out.",
  "AI 12 is not printed. Current, steam production and the control signal are scaled by 10.",
  "BV 2 and BV 3 only apply with the SB 8-relay option card."
