 "summary": "The Intelligent Valve is a hydronic control valve with a built-in flow sensor and temperature inputs, so it reports flow, power, energy and operating statistics. It talks BACnet IP (Modbus RTU runs in parallel) and can run as a dynamic control valve, a changeover valve, a flow temperature controller, a heating circuit controller or a differential pressure controller. Over BACnet IP the valve follows SpRel (AV 16), a 0-100 % setpoint that becomes a position, flow or power setpoint depending on CtlMod (MV 39).",

  "One object list covers every control function (dynamic control valve, changeover, flow temperature, heating circuit, differential pressure); the guide marks which objects each function uses. This file lists every object ID printed in the Operation, Balancing and Commissioning chapters.",
  "Some objects have a second instance in the differential pressure (Δp) function, and some analog inputs and outputs change instance with the selected signal type; each printed ID is listed with the same object name.",
  "Heating circuit and room heating objects are only active when the flow temperature control or heating circuit application is selected.",
  "Printed IDs kept as listed, with these exceptions: PrAdaPwrMax is printed 'AVI162' (listed as AV 162); ROpModSched is printed 'Schedule 1'; DrygFnctSta is printed both as MSV87 and AV87, and AV87 is also SbstTR, so only MV 87 is kept; TnHcrTFlVlvCtr (a reset time in seconds) is printed as MSV86, which is DrygFnct's ID, so its real ID is unknown and it is left out.",
  "Units are metric as printed (°C, m³/h, kW, kPa). Access is W where the guide's Write column says Y. Modbus register addresses are not reproduced."

  "enable": "The application and setpoint source are set at commissioning; PrSpSrc (MV 54) shows the result. Option 3 (Relative setpoint remote) means the dynamic control valve takes SpRel (AV 16) from BACnet IP; options 7 and 8 do the same for flow temperature and differential pressure setpoints. VovrMod (MV 92) can override the valve (fully open, fully closed, minimum or maximum flow and so on).",
