 "summary": "Intesis interface for one Hitachi commercial or VRF indoor unit on the AB remote-controller bus, serving BACnet MS/TP or Modbus RTU (DIP switch). It exposes 35 fixed objects: on/off, mode, setpoint, fan and up/down vane as _command/_status pairs, error code with reset, filter sign with reset, occupancy logic, a remote lock, a virtual-temperature function and a reset-behaviour setting.",

  "Sibling of the INBACHIT001R000 (listed separately); this model adds DIP switch read-backs and the ResetBehaviour object.",
  "The manual's object list gives ErrorAddress as AI 2 (clashes with ErrorCode); its property table says AI 4, used here. The list also spells FilterSignAddress as FilterSingAddress and ResetBehaviour as ResetBehavior; names here follow Object_Name.",
  "FanSpeed_command prints six states (up to Fan Speed 5) while its Present_Value range is 1..5 and FanSpeed_status has five; Fan Speed 5 may not be accepted.",
  "ErrorCodeM has 45 states; the Hitachi error code table is in the manual.",
