Speed control
First Claim
1. A control system for at least one aquatic application, a pump coupled to the at least one aquatic application, the control system comprising:
- a variable speed motor adapted to be coupled to the pump;
a memory storing a schedule of speed and timing, a first speed value, and a first time period;
a user interface coupleable to the variable speed motor,the user interface including a first button to select the first speed value and the first time period;
the user interface including a first visual indicator associated with the first button;
the user interface including an increase button and a decrease button to alter at least one of the first speed value and the first time period; and
the user interface including a visual display element to display a present speed value; and
a controller in communication with the variable speed motor, the memory, and the user interface, the controller operating the variable speed motor according to the schedule, the controller responding to activation of the first button by obtaining the first speed value and the first time period from the memory and initiating operation of the variable speed motor at a constant speed based on the first speed value for the first time period and subsequently operating the variable speed motor according to the schedule after the first time period.

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.
