Revitalize your whirlpool tub with the Hydro Systems CIDU-252-01-01-01 Keypad Replacement Retrofit Kit — a precise, durable upgrade that brings modern control to an aging system without the cost or downtime of a full unit replacement. If the original CIDU-252-01-01-01 keypad or its paired control box has failed or been discontinued, this retrofit delivers a complete, compatible overhaul that restores your spa's performance and reliability.

What makes this kit stand out

• Original-system compatibility with a modern touch — engineered to overhaul the existing electronic setup while pairing seamlessly with your tub's original air blower, preserving the familiar feel you rely on.
• Flexible, spa-worthy control — enjoy multiple adjustable speeds for tailored hydro-massage, dynamic wave and pulse modes, a precise 20-minute timer, and a dry cycle to purge moisture and extend component life.
• True retrofit, not replacement — designed to revive your whirlpool bath without ripping out the entire system, delivering long-lasting functionality while keeping your tub's core hardware intact.
• Straightforward upgrade path — if you need a new air blower to pair with the retrofit, there's a compatible model designed to integrate smoothly with this kit.
