Abstract:
Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller receives input of a performance value that is determined utilizing information from operation of the motor and compares the performance value to a reference value. The controller also is configured to prime and run the pump when the performance value equals the first reference value and to continue to do so until the performance value equals a second reference value. Alternatively, the controller receives user input of an amount of time the system can take to attempt to successfully prime the pump and is configured to operate the motor at maximum speed until the amount of time elapses.
