Hayward Salt & Swim 3C PRO Control Unit (30,000 Gallons) | W3SAS-PRO

Take your pool care routine to the next level with the genuine Hayward Salt & Swim 3C PRO Control Unit. Engineered specifically for in-ground pools up to 30,000 gallons, this advanced electronic controller delivers Hayward's legendary 3Cs of salt chlorination: unmatched comfort, ultimate convenience, and exceptional cost savings. By automatically managing your sanitation system, this unit coordinates the continuous conversion of ordinary pool salt into a self-renewing supply of pure, highly effective free chlorine. It eliminates the need to manually lift heavy chemical buckets, measure out powder, or store hazardous liquid chlorine jugs around your property. Instead, you can look forward to crystal-clear water all season long with a fraction of the physical labor.

This professional-grade PRO model features a heavy-duty design with durable 2-inch slip-fit union connections, making it an excellent choice for seamless integration into standard in-ground filtration plumbing layouts. Equipped with a highly intuitive LED indicator display panel, the control unit gives you real-time visibility into your system's operational status and salt levels. For times when your pool experiences heavy bather loads, intense rainstorms, or extreme heatwaves, the built-in Super Chlorination feature allows you to temporarily boost chlorine output to shock the water and prevent cloudy conditions or algae blooms before they start. Designed to plug directly into a standard 120V GFCI outlet, this control system offers a streamlined way to modernize your equipment pad while creating a safer, more natural, and highly efficient swimming environment for your family.
