 "summary": "These are the BACnet objects WaterFurnace publishes for its dual-compressor water-to-air heat pumps running the FX10 DDC controller. A BAS can read space, discharge and coil temperatures, occupancy and compressor/fan states, and can command occupancy, fan, compressor stages, the reversing valve and spare outputs directly. Setpoints and configuration live in flash-backed Analog/Multistate Values, so they should only be written occasionally.",

 "firmware": null,
 "default_device_instance": null,
 "notes": [
  "Output-type points are volatile and fall back to uncommanded after a power cycle; unlimited writes.",
  "Value-type points (AV/MV) are stored in flash (about 2,000,000 write life); never write them from automatic reset logic.",
  "Multistate numbers assume the BAS shows 255 as uncommanded; if yours shows 254, every state number is one lower (0=Off, 1=On).",
  "No engineering units are printed in the source; temperatures are presumably degrees F.",
  "The sheet does not state the BACnet transport."
