This product combines a pool equipment controller with a water chemistry controller to do more and save money. This aquatic controller is running a Linux web-server, which means you can configure, control, and monitor your pool or spa from any computer (touchscreen, iPhone, or PDA) with a browser that you already own. Say goodbye to expensive incomplete proprietary systems. Pool controller can send email notifications based upon pH, ORP, temperature, or any of (4) input values.
