Speed Control
First Claim
1. A pumping system for at least one aquatic application controlled by a user, the pumping system comprising:
- a pump;
a variable speed motor coupled to the pump;
a memory storing a first speed value and a second speed value;
a user interface including a first speed button to select the first speed value and a second speed button to select the second speed value, the user interface including an increase button and a decrease button for altering one of the first speed value and the second speed value;
the increase button and the decrease button being capable of an actuate and release operation to alter one of the first speed value and the second speed value;
the increase button and the decrease button being capable of a first touch and hold operation to alter one of the first speed value and the second speed value;
the first speed button and the second speed button capable of a second touch and hold operation to store in the memory a new speed value that replaces one of the first speed value and the second speed value;
the user selecting at least one of the first speed button, the second speed button, the increase button, and the decrease button to specify a current speed value;
the user interface displaying the current speed value to the user as the user alters the current speed value; and
a controller in communication with the variable speed motor, the memory, and the user interface, the controller obtaining one of the first speed value and the second speed value from the memory and operating the variable speed motor at a substantially constant speed based on the current speed value.

Abstract
A pumping system for moving water of a swimming pool includes a water pump, an infinitely variable speed motor, and an arrangement for operating the motor. In one example, the pumping system includes a memory configured to store a plurality of retained speed values, an arrangement for providing a plurality of retained speed values to the memory, and an arrangement for reading a selected one of the plurality of retained speed values from the memory. In addition or alternatively, the pumping system includes a storage medium for digitally storing a plurality of pre-established motor speed values and an arrangement for receiving input from a user to select one of the pre-established motor speeds. In addition or alternatively, the pumping system further includes an arrangement for restarting operation of the motor at a previously selected speed value when power supplied to the motor is interrupted during operation of the motor. A method for controlling the pumping system is also provided.
