 "summary": "The AVPT is a pencil-style thermal anemometer probe for duct air velocity, sold with either analog outputs or a BACnet MS/TP output. On BACnet it exposes velocity and air temperature as four Analog Inputs (each in imperial and metric), plus objects to set the MS/TP address, the baud rate and a factory reset.",

 "notes": [
  "Velocity and temperature are each given twice, in imperial and metric units, as separate objects.",
  "The overview table prints BV 1 as \"Restore Factory Defauls\"; the property table spells it \"Restore Factory Defaults\".",
  "Factory address is 127; the device instance follows the address until a specific instance is written."
