Nine auxiliaries covers an elaborate equipment pad: multiple colour lighting zones, a cleaner, a booster pump, water features and solar, with intake and return valve control built in for automated pool-to-spa changeover.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThis is a legacy part number.\u003c\/strong\u003e Pentair's Transition Guide supersedes 521908 with \u003cstrong\u003e523965\u003c\/strong\u003e, and it has dropped out of the current 2025–2026 catalogue. The re-numbering was driven by the salt cell moving from IntelliChlor IC40 to IntelliChlor Plus40 (523735). The system ships in an \u003cstrong\u003eIntelliCenter Load Center\u003c\/strong\u003e with a 150 A built-in circuit breaker subpanel and five pre-installed high-voltage relays, the i10PS personality adding five more for ten in total.
