  "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.",

  "remote_sensors": "AO 1 RoomTemperature_command sets the room temperature the MHI unit uses, but only when the gateway is configured as master of the X-Y bus; as slave the write has no effect.",
  "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, which matches the baud rate of another MS/TP device running a fixed rate.",

  "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.",
   "If an MHI wired remote is on the same bus, set master/slave roles so the two do not conflict."
