Abstract
A method and apparatus for automatically adjusting electrolytic production or feeding of a sanitizer such as halogen for treating a water body such as a swimming pool or spa. A microprocessor is responsive to sensors monitoring pH and temperature of the water body to predict demand for sanitizer which varies dependent on pH and temperature and direct a controller which automatically modifies the ON time during an ON/OFF cycle for the sanitizer production system in response to changing demand resulting from changing measurements in temperature and/or pH of the swimming pool water. The controller also modifies an ON/OFF cycle for a circulating pump when demand predicted by the microprocessor exceeds the capability of the sanitizer producer or feeder under an existing ON/OFF pump cycle.
