Control algorithm of variable speed pumping system

A pumping system for at least one aquatic application receiving inputs from a user, the pumping system comprising:

• a pump;
• a motor coupled to the pump;
• a filter coupled to the pump;
• and
• a controller in communication with the motor, the controller obtaining from a filter menu a total size of the at least one aquatic application as input by the user and a scheduled time including start and stop times for at least one cycle as input by the user, the controller calculating a filter flow value by dividing the total size by the scheduled time in order to self-adjust to any total size of the at least one aquatic application.

A pumping system for at least one aquatic application, the pumping system comprising:

• a pump;
• a motor coupled to the pump;
• and
• a controller in communication with the motor, the controller determining a current flow rate based on an input power to the motor, the controller determining whether the current flow rate is above a priming flow value in order to determine whether the pumping system is primed, the controller indicating a priming alarm if the pumping system is not primed before reaching a maximum priming time allotment.

A pumping system for at least one aquatic application, the pumping system comprising:

• a pump;
• a motor coupled to the pump;
• and
• a controller in communication with the motor, the controller obtaining a hardware input including at least one of input power and motor speed, the controller calculating shaft power based on the hardware input, the controller determining priming status based on the shaft power, the controller indicating a priming dry alarm if the shaft power is at least approaching zero for at least about ten seconds.

A pumping system for at least one aquatic application, the pumping system comprising:

• a pump;
• a filter coupled to the pump;
• a motor coupled to the pump;
• and
• a controller in communication with the motor, the controller performing routine filtration cycles, the controller automatically at least one of reducing and eliminating at least one of the routine filtration cycles when other operations provide additional water movement to achieve a desired turnover rate.
