The CAT 5500 is specifically designed for salt chlorine pool environments where monitoring salt concentration directly is critical. Choose the CAT 4000 for standard pH\/ORP control; choose the CAT 5500 when salt monitoring and dual ORP setpoints are required.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"padding:14px 0;\"\u003e\n    \u003csummary style=\"font-weight:600; cursor:pointer; font-size:15px; border:none;\"\u003eWhat does conductivity\/NaCl monitoring tell me?\u003c\/summary\u003e\n    \u003cp style=\"margin-top:10px; font-size:14px; line-height:1.6;\"\u003eConductivity monitoring measures the electrical conductivity of the water, which correlates directly to the salt (NaCl) concentration in a salt pool. The controller can display the actual salt level in PPM\/PPT, alert operators when salt is too low or too high, and provide the data needed to maintain optimal salt chlorinator performance without manual salt testing.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"padding:14px 0;\"\u003e\n    \u003csummary style=\"font-weight:600; cursor:pointer; font-size:15px; border:none;\"\u003eWhat are dual sanitizer setpoints used for?\u003c\/summary\u003e\n    \u003cp style=\"margin-top:10px; font-size:14px; line-height:1.6;\"\u003eDual ORP setpoints allow the CAT 5500 to control both a primary sanitizer (e.g., the salt generator) and a secondary backup chemical feeder. If the primary sanitizer can't bring ORP up to the primary setpoint, the secondary feeder activates — providing an automatic safety net for periods of heavy bather load or equipment maintenance.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails style=\"padding:14px 0;\"\u003e\n    \u003csummary style=\"font-weight:600; cursor:pointer; font-size:15px; border:none;\"\u003eIs it compatible with the Saline C 6.0 salt generator?\u003c\/summary\u003e\n    \u003cp style=\"margin-top:10px; font-size:14px; line-height:1.6;\"\u003eYes. The CAT 5500 is described as the \"perfect complement\" to the Hayward Saline C® 6.0 salt chlorine generator — the two systems are designed to work together for complete automated salt pool water chemistry management.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n\u003c\/div\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":48955319746811,"sku":"CAT5500-WIFICA","price":6900.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0807\/4418\/6107\/files\/cat_5500_44a0_30be1ccb-49bd-4a39-8245-a75bcec7075e.jpg?v=1780908359","url":"https:\/\/clearflowpoolsupply.com\/products\/hayward-cat-5500-chemical-control-system-wifi","provider":"ClearFlow Pool Supply","version":"1.0","type":"link"}
