 "summary": "The CQ24A-BAC is a small rotary actuator for Belimo CQ zone valves with a built-in BACnet MS/TP interface. The BMS writes a 0-100 % position setpoint to AO 1 and reads back relative and absolute position, a summary status and a device status. An override object can force the actuator open, closed or to maximum.",
