 "summary": "One-unit Intesis interface that plugs into the S21 socket of a Daikin residential indoor unit and exposes it on BACnet MS/TP as 34 fixed objects. Every function has a _command object to write and a _status object to read back. It adds occupancy logic, a remote-controller lock, humidification (on units that have it) and a virtual-temperature function that uses a BMS room sensor.",

 "notes": [
  "This MS/TP model has a larger object set than the older INBACDAI001I000 gateway (BACnet IP and MS/TP, listed separately): occupancy objects, LockRemoteControl, humidification and outdoor temperature are added.",
  "Object names are taken from each object's Object_Name property. The summary table in the manual spells a few with different capitals (Setpoint_status, UserSetpoint_status, Setpoint_command, OccupiedCoolSetpoint and the other occupancy setpoints, UnoccupiedDeadBandAction).",
  "Up/down and left/right air direction only offer Stop and Swing on this model.",
  "ErrorCodeM has 156 states; the full Daikin error code table is in the manual.",
  "Temperature units follow the °C/°F DIP switch (SW2 position 8)."

  "heartbeat": null,
  "remote_sensors": "Write the BMS room temperature to AO 1 RoomTemperature_command and the setpoint to AO 0. The gateway then runs its Virtual Temperature function and recalculates the setpoint it sends to the unit; BI 14 VirtualTempActive shows it is active and AI 17 UserSetPoint_status shows the BMS setpoint.",
  "setup": [
   "Default device instance 246000; in automatic mode it is 246000 + the MS/TP MAC address set on DIP switch SW2.",
   "Writing Object_Identifier from BACnet switches the gateway to manual addressing until a factory reset.",

   "The Occupancy MV and its four setpoint AVs drive built-in logic; leave Occupancy at 3 (Disabled) if the BMS handles scheduling.",
