The Polaris Watermatic C310 Controller is designed to automatically monitor and maintain the sanitizer level in swimming pools, spas and any circulating water system that requires water chemistry management. The C310 will also monitor the pH balance. The C310 is designed for easy installation and simple operation.

The controllers are designed to be used in conjunction with the Polaris Watermatic G1000 Feeder.

During the filtration cycle of the pool or spa, the sanitizer level is maintained by a constant measurement of the ORP (Oxidation- Reduction-Potential). Measurements are displayed on the controller's ORP light bar array (see drawing below). If the sanitizer level (ORP) falls below the preset point, the controller will activate the chemical feeder until the desired level is reached.

The C310 also displays the pH level on the pH light bar array, although no control or maintenance is provided.
