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 determines an actual power consumption of the motor and compares the actual power consumption to a reference power consumption. The controller also determines that the pump is in an unprimed condition if the actual power consumption is less than the reference power consumption and that the pump is in a primed condition if the actual power consumption is at least equal to the reference power consumption.
