 "equipment_type": "VRF BACnet gateway (per indoor unit)",
 "applies_to": "Sinclair SDV5 VRF indoor units reached over the outdoor-unit XYE bus through a GW-BAC gateway.",
 "summary": "The GW-BAC connects up to four XYE buses (64 indoor and 32 outdoor units per bus, 256 indoor units in total) to BACnet IP. Every indoor unit appears as its own BACnet device with the same small object set: on/off, mode, fan speed, setpoints, locks, room temperature and error code. This file lists that per-indoor-unit object set. Outdoor units appear as separate devices with their own read-only object list.",

 "notes": [
  "Each indoor unit is its own BACnet device. Device instance = BACnet network number x 10000 + 485 port number x 1000 + indoor unit address. Ports are numbered 0-3 (0 = the port next to the Ethernet jack); indoor addresses are 0-63.",
  "Object instances are the same in every indoor unit device; only the device instance changes.",
  "Outdoor units are separate devices: network number x 10000 + port x 1000 + 100 + outdoor address (0-31). Their objects (mode, on/off and alarm status, ambient temp, compressor frequencies and discharge temps, pressures, error code, fan speeds) are in section 4-2 of the manual and are not listed here.",
  "Not every indoor model supports every object; cooling-only systems do not support Heat or Auto mode.",
  "Temperatures are in °C. Malfunction Code numbers map to display codes (1-20 = A0-AU, 21-40 = b0-bU, and so on) in the manual's error code table.",

   "Switching a unit on with BV 1 restores its last mode, fan speed and setpoint; a unit that was off when the gateway started defaults to cool, 24 °C, low fan.",

   "In Auto mode the cooling setpoint (AV 2) must be at or above the heating setpoint (AV 3), or the gateway changes the heating setpoint to match.",
   "Re-addressing an indoor unit or moving it to another port changes its device instance."
