Each indoor-unit device has 46 objects: on/off and fault status, mode, fan speed, setpoints (single and auto dual), room temperature, error code, swing, setpoint limits, locks, coil temperatures and EXV opening, plus AO/BO commands for mode, setpoints, fan, swing, limits and locks.",

  "No units are given in the manual.",
  "The manual describes inputs as read-only and outputs as write-only; no priority array is documented.",
  "AO 1 Ajuste del modo also turns the unit on (239) or off (240). AO 15 is printed as SetLimtUDSwing on its detail page (SetLimitUDSwing in the object list)."
