A method of operating a pumping system for an aquatic application based upon performance of multiple water operations is disclosed. The method includes providing a pump and a motor coupled to the pump, and a controller including a variable speed drive that is in communication with the motor. The method also includes: operating the motor in accordance with a first water operation, wherein the first water operation includes a first start time, end time, and water flow rate; operating the motor in accordance with a second water operation, wherein the second water operation includes a second start time, end time, and water flow rate; and altering the first water operation in response to performance of the second water operation.

Pumping system with power optimization

A system includes a motor and a control system operating as a master controller with respect to at least one function, the control system including an automation system with a user interface having a display connected to the automation system. A controller is located remotely from the control system and coupled to a pump or the motor. The controller operating as a slave controller with respect to the at least one function when connected to the control system. The controller is in communication with the motor and the control system, and transmits information to and receives information from the control system over at least one communication link. The controller operates independently to control the motor when disconnected from the control system.

Pumping system and method having an independent controller

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.

Speed control

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.

A pumping system for at least one aquatic application controlled by a user. The pumping system includes a pump and a motor disposed in a first housing and coupled to the pump. A user interface is associated with a second housing, the second housing defined by a base portion shaped to interact with the first housing and a user interface portion that carries a plurality of control buttons, wherein the second housing is selectively positionable among a plurality of positions relative to the first housing.

Pumping system with housing and user interface

A pumping system for moving water of a swimming pool includes a water pump, a variable speed motor, and an arrangement for controlling the variable speed motor. The pumping system further includes an auxiliary device operably connected to the arrangement for controlling, which is capable of receiving a parameter from the auxiliary device. The arrangement for controlling is capable of independently controlling the variable speed motor without receipt of a parameter from the auxiliary device. In addition or alternatively, the arrangement for controlling is operable to selectively alter operation of the motor based upon the parameter.

Pumping system with two way communication

The present invention provides a pumping system for moving water of a swimming pool, including a water pump and a variable speed motor. In one example, a target volume amount of water and an operational time period is provided, and the operational time period is altered based upon a volume of water moved. In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption.

A method for controlling stray electromagnetic fields for a vehicle with an inductive charging system and a method for providing feedback to a vehicle operator for an inductive charging system is characterized by the addition of alignment coils to a vehicle mounted secondary coil. The methods provide sensors to detect the relative positions of the primary coil and secondary coil by determining voltages induced in the alignment coils by a magnetic field generated by the primary coil. The methods include providing feedback to the vehicle operator to guide the alignment of the secondary coil relative to the primary coil and directing the vehicle operator to position the secondary coil within an alignment zone so as to control stray electromagnetic fields.

Method and apparatus for controlling stray electromagnetic fields and providing operator feedback when aligning a vehicle with an inductive charging system

A method and apparatus for aligning a vehicle with an inductive charging system is characterized by the addition of alignment coils to a secondary coil on the vehicle. For efficient inductive charging, it is necessary that the vehicle mounted secondary coil be aligned with a stationary primary coil of a transformer of the inductive charging system. When the primary coil is energized, it produces a magnetic field which induces a voltage in the alignment coils as a function of the proximity of the alignment coils to the central axis of the primary coil. The voltage differential between opposed pairs of alignment coils is determined by a comparator which then generates a directional signal which can be used by the operator of the vehicle to position the vehicle for closer alignment of the vehicle secondary coil with the primary coil and more efficient charging.

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.

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.
