Control algorithm of variable speed pumping system
First Claim
1. A pumping system for at least one aquatic application receiving inputs from a user, the pumping system comprising:
- a pump;
a variable speed motor coupled to the pump;
a controller in communication with the variable speed motor, the controller configured to;
determine a start time and a stop time of a filter cycle based on the inputs received from the user,determine a start time and a stop time of an additional operation,one of (a) eliminate the filter cycle, (b) adjust the start time of the filter cycle, and (c) adjust the stop time of the filter cycle, when the additional operation overlaps the filter cycle, andoperate the variable speed motor to perform at least one of the filter cycle and the additional operation.

Abstract
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.
