 "summary": "The JR..A-BAC-.. is a Belimo rotary actuator for butterfly valves with BACnet MS/TP on board. The BMS writes a % setpoint to AO 1 and reads position and status; two extra sensor inputs (0-10 V, passive temperature or switch) can be read over the bus. The setpoint can also come from a 0-10 V signal, chosen with SpSource (MV 122).",

  "heartbeat": "AV 130 BusWatchdog, 5-3600 s, default 120 s. If neither AO 1 nor MV 1 is rewritten within the timeout the actuator runs the action in MV 130 BusFailAction (default None) and MV 135 shows Bus Watchdog active.",
