Abstract: A system for predicting HVAC equipment failure includes an actuator and a controller. The actuator is coupled to the HVAC equipment and configured to drive the HVAC equipment between multiple positions. The actuator includes a processing circuit configured to collect internal actuator data characterizing an operation of the actuator and a communications circuit coupled to the processing circuit. The communications circuit is configured to transmit the internal actuator data outside the actuator. The controller is configured to provide control signals to the actuator and receive the internal actuator data from the actuator. The controller includes a failure predictor configured to use the internal actuator data to predict a time at which the HVAC equipment failure will occur.

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.

Abstract: A actuator in a HVAC system includes a motor and a drive device driven by the motor. The drive device is coupled to a movable HVAC component for driving the movable HVAC component between multiple positions. The actuator further includes a main actuator controller that determines when the drive device is approaching an end stop and a pulse width modulation (PWM) speed controller that generates a PWM speed output for controlling a speed of the motor. The PWM speed controller sets the PWM speed output to zero in response to a determination that the drive device is approaching the end stop. The PWM speed controller then increases the PWM speed output until the end stop is reached, thereby causing the speed of the motor to increase as the drive device approaches the end stop.

Abstract: An actuator in a HVAC system includes a motor and a drive device driven by the motor. The drive device is coupled to a movable HVAC component for driving the movable HVAC component between multiple positions. The actuator further includes a main actuator controller. The main actuator controller includes end stop location memory that stores one or more end stop locations indicating expected locations of the one or more end stops. The main actuator controller further includes an end stop location recalibrator that runs an automatic recalibration process to determine and set recalibrated end stop locations. The end stop location recalibrator runs the automatic calibration process in response to detecting that the drive device has unexpectedly stalled at a location other than a stored end stop location.
