Abstract:
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.
