Abstract: Actuated bypass valves for use in swimming pool systems are disclosed. The valves automatically bypasses a swimming pool heating unit except when the heating unit is placed into service. The disclosed valves reduce the energy requirements of the circulation pump when the heating unit is bypassed. The valves comprise a tee-shaped valve body. Flow within the valve body is controlled by a sliding plate which slides relative to a stationary plate, where the sliding plate and the stationary plate each has a plurality of openings. Means for actuating the valves may comprise a 24 VAC solenoid. Minimal travel of the sliding plate is necessary for the valve to open from a minimum flow area to a maximum flow area. Methods for utilizing the disclosed valves are also disclosed.

Abstract: A system and method for reducing the energy consumption of a swimming pool cleaning system is disclosed. The system operates the skimmer for a first predetermined time period inputted into a programmable controller. At the conclusion of this time period, the programmable controller activates an actuator which causes a diverter valve or in-line valve to isolate and selectively operate a suction vacuum for a second predetermined time period. Isolating and selectively operating the suction vacuum from the skimmer allows the centrifugal pump to be driven by a motor in low speed mode to be used all of the time for skimming and cleaning operations, thereby greatly reducing energy consumption.

A similar system is disclosed for isolating and selectively operating a pressure cleaner. Methods for employing both systems are disclosed.
