1. A control system for at least one aquatic application, the control system comprising:
- a pump;
a motor configured to be coupled to the pump;
a controller including a processor, memory, and a variable speed drive, the controller is in communication with and configured to control the motor; and
a user interface coupled to the controller, the user interface includinga first speed button associated with a first speed value stored in the memory, the controller configured to retrieve the first speed value from memory and drive the motor at a constant speed based on the first speed value upon actuation of the first speed button,a second speed button associated with a second speed value stored in the memory, the controller configured to retrieve the second speed value from memory and drive the motor at a constant speed based on the second speed value upon actuation of the second speed button, andan increase button and a decrease button, the controller configured to alter one of the first speed value and the second speed value to a current speed value upon actuation of one of the increase button and the decrease button and drive the motor at the current speed value,the controller configured to store the current speed value to the memory in place of one of the first speed value to associate the current speed value with the first speed button and the second speed value to associate the current speed value with the second speed button based on user input via the user interface.

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.
