Abstract

Embodiments of the invention provide a pumping system for at least one aquatic application controlled by a user. The pumping system includes a pump, a variable speed motor, a memory, and a controller. The pumping system includes a user interface with a first speed button, a second speed button, an increase button, and a decrease button. The buttons provide an actuate and release operation, a first touch and hold operation, and a second touch and hold operation. The controller operates the variable speed motor at a substantially constant speed based on a current speed value selected by the user using the buttons.
