Abstract
A pumping system for an aquatic application includes a motor to be coupled to a pump and a controller in communication with the motor. The controller is configured to determine a speed of the motor, determine a current performance value of the pumping system, compare the current performance value to a referenced performance value, determine an adjustment value based upon the comparison of the reference and current performance values, and adjust a speed of the motor based on the adjustment value.
