 "applies_to": "ONICON System-10 BTU meters fitted with the BACnet network interface (BACnet MS/TP or BACnet IP).",
 "summary": "The System-10-BAC interface puts an ONICON System-10 BTU meter on BACnet MS/TP or BACnet IP. It exposes energy and flow rate, supply and return temperatures, energy and volume totals, an auxiliary pulse total and the operating mode, plus BVs that zero each total. The meter runs in single, dual or bi-directional mode, which decides which totals carry data.",

 "notes": [
  "Operating mode decides which objects carry data: single mode uses only AV 1/AV 2 and BV 11/BV 12; dual mode also uses the mode 2 totals AV 3/AV 4 and BV 13/BV 14.",
  "AV 7 to AV 11 are used internally and are not part of the published list.",
  "The per-object tables print Object_Name only as \"Various\"; names here are the object descriptions from the main object table (section 2.2). The analog value table uses a few shorter variants such as \"Aux Input Total\" and \"Operating Mode\", and AV 13 appears only there.",
  "Units shown are defaults. Energy rate can be Btu/h, kW or tons; flow l/s, l/min, l/h, m3/h, gpm, ft3/s or ft3/min; totals Btu, ton-hours or kWh and liters, m3, gallons or ft3.",
  "There is no per-object read/write column; the zero BVs are marked W because the manual says to write them to reset a total."
