 "summary": "The Energy Valve V3 is a pressure-independent characterized control valve with a flow sensor and two temperature sensors, so it reports flow, delta T, power and heating/cooling energy. It talks BACnet MS/TP or BACnet IP. AO 1 is a % setpoint read as position, flow or power depending on ControlMode (MV 100); the setpoint only follows the bus when SpSource (MV 122) is Bus.",
