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, 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

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.

Control algorithm of variable speed pumping system

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, and an arrangement for providing two-way communication between the arrangement for controlling and the auxiliary device. The arrangement for controlling is capable of receiving a parameter from the auxiliary device through the arrangement for providing two-way communication. In one example, 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. In addition or alternatively, the arrangement for controlling is configured to optimize a power consumption of the variable speed motor over time based upon the parameters received. A method for controlling the pumping system is also provided.
