The Polaris Watermatic C1500 Controller automatically monitors and maintains either the sanitizer level or the pH balance in swimming pools, spas, or any circulating water system that requires water chemistry management. Designed for easy installation and simple operation, it can be used with liquid feed pumps, granular feeders, tablet erosion feeders, and ozone generators. It is not warranted or recommended for use with chlorine gas systems.

During the filtration cycle, the Watermatic C1500 controller maintains sanitizer levels or pH balance by constantly measuring the Oxidation-Reduction-Potential (ORP) and pH balance of the water. If the sanitizer level (ORP) or pH falls below a predetermined set point, the controller activates the chemical feeder.

Settings and measurements are displayed on an easy-to-read LCD text screen and adjustments are made via a touch key pad.
