 "summary": "The DCM014A51 software option turns a Daikin intelligent Touch Manager into a BACnet IP server. The iTM acts as a BACnet virtual router: each indoor unit becomes its own virtual BACnet device carrying the same 37-object list, and a separate system control device holds schedule, auto-changeover, timed-override and forced-off objects. Objects can be enabled or disabled per unit during commissioning, so a site may expose fewer points than listed.",

 "firmware": null,

 "notes": [
  "Each indoor unit is a separate virtual BACnet device behind the iTM's virtual router; instances 1-37 repeat on every indoor unit device.",
  "The last four points (BO 1, BO 2, MV 3, BO 4) live on the iTM system control device, not on indoor unit devices.",
  "Temperature units follow the iTM regional setting (Celsius or Fahrenheit).",
  "Commands that the indoor unit rejects are reverted by the iTM after about 10 minutes.",
  "Only the remote-controller group's designated unit (#0) should receive commands in a multi-unit group.",
  "Freeze Protection (BI 37) is only available on certain indoor unit models."

  "enable": "Writing Occupancy Mode (MO 1) is the start/stop: Occ sends On, Unocc sends Off, Standby sends On with energy saving (setpoint offset by 3.6 F / 2 C).
