 "summary": "The Midea GW3-BAC gateway serves V8 VRF systems on BACnet IP and creates one virtual BACnet device per outdoor unit. Each outdoor-unit device has 42 objects: on/off and fault status, mode, fan speeds and status, outdoor temperature, compressor frequencies, status, discharge temperatures and currents, high and low pressure, error code, EXV openings, solenoid valves, auxiliary electric heaters and an emergency-stop command.",

  "The manual is in Spanish; object names and state texts are kept as printed. The device may report different (for example English) names.",
  "Every VRF unit is its own virtual BACnet device. Device ID = ABCDEFG: ABC = gateway BACnet setting (2-400), D = RS-485 port (0-2), E = refrigerant system (0-7), FG = unit address (indoor 0-63, outdoor 96-99). Example: 192405 = setting 19, port 2, system 4, indoor unit 05.",
  "No units are given in the manual.",
  "The manual describes inputs as read-only and outputs as write-only; no priority array is documented.",
  "The object list names AI 2/3 Velocidad del ventilador 1/2 and BI 20/21 Manivela 1/2; the detail pages name them Fan1/Fan2 and Crank1/Crank2 (used here). BI 2 has no name on its detail page; the list name is used."
