 "summary": "The IMMP-BAC(A) (K05.2-BACNET(A)) is a Midea building control gateway that publishes every connected VRF indoor unit, outdoor unit and HTHM hydronic module as its own BACnet IP device. This is the object set of one indoor unit device: on/off, mode, fan speed, setpoints and lock commands plus room, coil and discharge temperatures and the error code.",

 "notes": [
  "The manual is in Spanish (Midea Spain); object names are kept as printed and the English descriptions are ours.",
  "Each unit is its own BACnet device. Indoor unit device instance = BACnet network number x 10000 + RS-485 port (0-3) x 1000 + indoor address (0-63); outdoor unit = network x 10000 + port x 1000 + 100 + outdoor address (0-31).",
  "Some models do not support every object (for example cooling-only systems have no heat or auto mode).",
  "Error codes are numbered 1-260 and map to the display codes A0...UU (blocks of 20 per letter).",
  "The doc marks objects L (read) or L/E (read and write the unit state); there is no priority-array information."
