Abstract: An actuator in a HVAC system includes a mechanical transducer, an input data connection, a feedback data connection, and a processing circuit. The processing circuit is configured to use a master-slave detection signal communicated via the feedback data connection to select an operating mode for the actuator from a set of multiple potential operating modes including a master operating mode and a slave operating mode. The processing circuit is configured to operate the mechanical transducer in response to a control signal received via the input data connection according to the selected operating mode.
