 "summary": "A one-unit Intesis interface that sits on a Hitachi indoor unit's remote-controller bus and serves it as a BACnet MS/TP or BACnet IP device. It exposes 31 fixed objects (on/off, mode, setpoint, fan, louvre, room temperature, errors, filter, occupancy logic and remote-controller lock). Several indoor units on the same remote-controller bus can be connected but they are all driven as one group.",

  "summary": "Connect the gateway to the indoor unit (two-wire A/B remote-controller bus, gateway port RC2, up to 500 m), set the BACnet network on its DIP switches, then write the _command objects (on/off, mode, setpoint, fan) and read back the matching _status objects. One gateway serves one indoor unit (or one remote-controller group), so give each gateway its own MAC address and device instance.",

  "enable": "No enable point or BMS/local switch is documented; the gateway accepts BACnet commands as soon as it is communicating with the unit. A wired remote controller can still be used in parallel; BV 2 LockRemoteControl locks it.",
  "heartbeat": null,
  "remote_sensors": "Write a BMS room temperature to AO 1 RoomTemperature_command. BI 14 VirtualTempActive shows whether the gateway is using it, and AI 17 UserSetPoint_status shows the user setpoint written from BACnet while it is active (AI 0 then shows the setpoint actually applied).",
  "setup": [
   "BACnet MS/TP or BACnet IP is chosen with a DIP switch (MS/TP is the default); switch changes need a power cycle.",
   "BACnet IP: factory static IP 192.168.100.246; change it (or select DHCP) with the Intesis configuration tool.",
   "MS/TP MAC address 0-127 is set on DIP switches; baud rate is DIP-selectable (9600-115200) with autobaud as the default.",
   "Default device instance 246000. In automatic mode the instance is a base (246000, changeable in the configuration tool) + the SW2 MAC address; it can also be set manually or by writing Object_Identifier.",
   "SW4 sets the gateway as slave (default) or master on the Hitachi A/B bus.",

  ],
  "gotchas": [
   "Every function has a separate _command (AO/BO/MO, commandable) and _status (AI/BI/MI) object; write the command, read the status.",
   "Temperatures follow the Celsius/Fahrenheit DIP switch; the BACnet Units property changes with it.",
   "The Occupancy MV and its four AVs drive built-in logic that sets mode, setpoint and on/off; leave Occupancy at 3 (Disabled) unless you use it, and any manual on/off, mode or setpoint change cancels it.",
   "Several indoor units on one A/B bus are commanded together; individual commands to them are not possible."
