ABSTRACT:
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.
