 "summary": "The PR..-BAC-.. is a Belimo rotary actuator for butterfly valves with BACnet MS/TP on board. The BMS writes a % setpoint to AO 1 (0 up to the Max limit in AV 98) and reads position and status; two sensor inputs can be read over the bus. The setpoint can also come from a 0-10 V signal, chosen with SpSource.",
