 "summary": "The BUPNF product data sheet includes the BACnet MS/TP object list of its VRU-...-BAC control electronics: 39 objects (Device not counted). The BMS writes the relative setpoint to AO 1 (flow, pressure or damper position, depending on MV 2 ApplicationSel), can force states with MO 1, and reads airflow, differential pressure, damper position and five status objects.",

  "The PICS names the product VRU-D3-BAC, VRU-M1-BAC, VRU-M1R-BAC; the object list follows the Belimo VAV-Universal VRU numbering, so it shares firmware with that Belimo product.",
  "Several objects go Out_Of_Service depending on MV 2 ApplicationSel, MV 122 SpSource or MV 220 Sens1Type (see the status-flag notes in the data sheet).",
  "SpSource leaves the factory set to Analogue; set it to Bus before writing AO 1.",
  "The object name RmPCasacade (MV 10) is spelled this way in the data sheet."
