 "summary": "One-unit Intesis interface that plugs into the CN105 socket of a Mitsubishi Electric indoor unit and exposes it on BACnet MS/TP as 31 fixed objects. Each function has a _command object to write and a _status object to read back. It includes left/right vane control, occupancy logic, a remote-controller lock and a virtual-temperature function that uses a BMS room sensor.",

 "notes": [
  "This MS/TP model has more objects than the older INBACMIT001I000 gateway (BACnet IP and MS/TP, listed separately): left/right vane, RoomTemperature_command, virtual temperature, DIP switch status and serial number are added.",
  "Object names are taken from each object's Object_Name property; the summary table spells some with different capitals (UserSetpoint_status, Setpoint_command, the occupancy setpoints, UnoccupiedDeadBandAction).",
  "AirDirectionLR_command gives Present_Value 1..6 and Number_Of_States 6 in its property table, but its state table shows 7 states (Pos1-Pos6 Wide, Swing) like the status object; the state table is used here.",
  "Fan Speed 1 is the Silent speed on units that have it; available fan speeds and vane positions depend on the indoor unit.",
  "Temperature units follow the °C/°F DIP switch (SW2 position 8)."

  "enable": "No enable point is documented; the gateway accepts commands as soon as it talks to the unit. BV 2 LockRemoteControl can lock out the wired remote.",
  "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": [
