It monitors pH and sanitizer activity around the clock and feeds acid or base and sanitizer in proportion to demand.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is in this package\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe controller and the pH and ORP sensors. The flow cell and flow switch that come in Hayward's complete CAT 2000 packages are not included, which suits a facility replacing a controller on an existing installation. Hayward treats the flow sensor as required, so the controller must be wired to one before it is put into service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow it controls the water\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe controller comes set to pH 7.5 and ORP 650 mV. ORP measures how active the sanitizer is rather than how much of it is present, and the controller paces feed to the gap between each reading and its setpoint. High and low alarms, overfeed timers, a pH interlock and an optional pH priority guard against feeding into bad water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it fits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt works with chlorine, bromine and salt systems, has a chlorine generation interface and a remote alarm relay, and reports through an RS232 serial port. The enclosure is glass filled polycarbonate rated NEMA 4X, and the controller is certified to NSF\/ANSI 50.\u003c\/p\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":68353713963220,"sku":"CHT-45-1005","price":2468.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/hayward-cat2000cso-cat-2000-controller.jpg?v=1794330827","url":"https:\/\/www.activepoolsupply.com\/products\/cat-2000","provider":"Active Pool Supply","version":"1.0","type":"link"}
