 "summary": "BACnet MS/TP-only Intesis interface for one Mitsubishi Heavy Industries indoor unit, connected anywhere on the X-Y remote-controller bus. It exposes 35 fixed objects: on/off, mode, setpoint, fan and up/down vane as _command/_status pairs, error code, error and filter resets, occupancy logic, a remote lock, outdoor temperature, the Center/Remote control state and a virtual-temperature function.",

  "Fan speed Auto (state 1) may be missing on older indoor units.",
  "Object names follow each object's Object_Name property where it differs only in capitals (SetPoint_status, SetPoint_command, OccupiedCoolSetPoint and siblings, UnoccupiedDeadbandAction).",

  "remote_sensors": "With the gateway as X-Y header (SW1-1 on), reading temperature from the remote (SW1-2 on) and the unit set to use the remote's sensor, the value written to AO 1 RoomTemperature_command becomes the unit's reference temperature; until a valid value is written the unit may show a thermistor error.
