Abstract
In accordance with one aspect, the present invention provides a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, an interface associated with the pump designed to receive input instructions from a user, and a controller in communication with the motor. The controller determines a blockage condition based on a power consumption value of the motor, and further includes an auto-restart function that is designed to allow the pump to automatically restart after detection of the blockage.
