A swimming pool control system automatically controls the daily maintenance functions of a swimming pool. The control system actively monitors system conditions, makes adjustments for abnormal conditions, and provides remote feedback of system problems during its daily cycle. In addition, the control system provides operator assisted manual override operation and control of additional auxiliary equipment. The system includes a novel filter valve, a novel water level system and a novel suction valve that can be run and monitored non-manually by a digital controller.

[ What is claimed is:] [1.] An automated pool maintenance system for use with a water supply line, a water waste line, a pool fill line, and a pool drain line, comprising:a pump for fluid communication with said pool drain line;a filter having a filter input port and a filter output port;a multi-port valve body having,a first port for fluid communication with the filter input port,a second port for fluid communication with the filter output port,a third port for fluid communication with the water waste line, anda fourth port for fluid communication with the pool fill line,an actuator connected to the multi-port valve body to control fluid connection between said valve body ports, the actuator including:a rotor arranged adjacent to the valve body, and having a high pressure input for fluid communication with the pump and also having a low pressure output, and rotating relative to the valve body to select a fluid flow condition originating at at least a first selected port of the valve body and continuing through at least a second selected port of the valve body by aligning the high pressure input to the first selected port and the low pressure output to the second selected port;a biasing mechanism applying a force on said rotor tending to disengage the rotor away from the valve body;a solenoid which, when energized, applies a counter force on said rotor in a direction counter to said force of the biasing mechanism, whereby the rotor moves into an engaged position with said valve body when the solenoid is energized and into an disengaged position with said valve body when the solenoid is de-energized;a motor to rotate the rotor when the rotor is in the disengaged position;a water level sensor for fluid communication with the pool drain line to sense the pool water level,a pressure sensor for fluid communication with the pump and high pressure input of the rotor to sense the pressure of fluid output by the pump;an electronically controlled valve regulating fluid flow from the water supply line to the pool fill line; andan electronic controller for electrical connection to the pump, the solenoid, the electronically controlled valve, the motor, the water level sensor, and the pressure sensor, whereby the electronic controller automatically:filters pool water by activating the actuator to align the high pressure input of the rotor to the first port of the valve body and to align the low pressure output of the rotor to the second and fourth ports of the valve body, and then activating the pump;recognizes a high pressure condition from the pressure sensor, and backflushes the filter by activating the actuator to align the high pressure input of the rotor to the second port of the valve body and to align the low pressure output of the rotor to the first and third ports of the valve body, and then activating the pump;recognizes an overfull condition from the water level sensor, and wastes pool water by activating the actuator to align the high pressure input of the rotor to the third port of the valve body, and then activating the pump; andrecognizes an underfull condition from the water level sensor, and fills the pool with water from the water supply line by activating the electronically controlled valve.
