Abstract

The present invention relates to a control system adapted to control water flow in a swimming pool system including a swimming pool having a filter tank. The pool control system includes a control circuit for controlling at least a first pool water valve assembly and a second valve assembly so as to control water flow to the filter tank and from the filter tank to the swimming pool. The control circuit is adapted to maintain the water levels in the filter tank and swimming pool to within a prescribed water level. Each pool water valve assembly is preferably fitted with a potentiometer and air solenoid coupled to the control circuit for respectively determining the position of each respective water valve and controlling the position of each water valve. The system also features a central, programmable processing unit and apparatus for transmitting data between a remote location and the processing unit.
