摘要： 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.

摘要： Embodiments of the invention provide a pumping system for at least one aquatic application. The pumping system includes a pump, a motor coupled to the pump, and a controller in communication with the motor. The controller is configured to store a timeout time value. The controller is also configured to initiate a pump priming process and subsequently initiate a timeout counter to begin counting a counter time value. The controller is configured to initiate a timeout interrupt routine that interrupts the pump priming process when the counter time value exceeds the timeout time value. The timeout interrupt routine includes shutting down the motor.

摘要： A pumping system includes a pump for moving water. In one aspect, this is in connection with performance of an operation. The system includes a variable speed motor operatively connected to drive the pump. A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate indicative value toward a constant. A value indicative of flow pressure is determined and the motor is controlled to adjust the flow pressure indicative value toward a constant. A selection is made between flow rate control and flow pressure control. In another aspect, the pump is controlled to perform a first operation, and is operated to perform a second water operation. Control of operation of the pump to perform the first water operation is altered in response to operation of the pump to perform the second operation.

摘要： A pumping system including a pump, a motor coupled to the pump, an automation system, and a pump controller located remotely from the automation system. The pump controller is coupled to at least one pump and the motor, and the pump controller is in digital communication with the motor, the automation system, and at least one auxiliary device. The pump controller transmits data to, and receives data from, the automation system and at least one auxiliary device over at least one communication link and operates the motor based on information entered into the automation system and received from the automation system. The pump controller selectively alters an operation of the motor based on the information received from one of the automation system or parameters received from the at least one auxiliary device. During a lockout state, the pump controller selects one of ignoring, delaying, or rescheduling a water
