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 is configured to store a timeout time value. The controller is also configured to initiate a pump priming process and subsequently initiate a timeout counter to begin counting a counter time value. The controller is configured to initiate a timeout interrupt routine that interrupts the pump priming process when the counter time value exceeds the timeout time value. The timeout interrupt routine includes shutting down the motor.
