Zodiac – pH Controller PCB with Blue LCD Display (from 2008)

This is a genuine Zodiac replacement printed circuit board (PCB) featuring a blue LCD display, designed to restore full electronic control to Zodiac automatic pH dosing regulators manufactured from 2008 onwards. The board handles all user-interface functions — reading, displaying, and regulating pH setpoints — making it the heart of the controller unit.

Compatibility

This PCB is a direct OEM replacement for the following Zodiac pH regulator families: pH Perfect (W500702), pH Expert (W500708), pH Clever (WW000031), and GenpH (WW000253). It is suitable for units produced from 2008. Always verify your regulator’s reference number before ordering to ensure a correct match.

Why genuine matters

As an original Zodiac spare part, this board is manufactured to the exact electrical and firmware specifications of your regulator. Using a genuine replacement ensures accurate pH readings, reliable dosing signals, and continued compatibility with your existing sensors and pump connections — avoiding the risks that come with non-OEM alternatives.

Installation

PCB replacement involves working inside the controller enclosure and handling mains-connected components. Installation should be carried out by a qualified pool technician or electrician. Ensure power is fully isolated before beginning work, and follow the appropriate Zodiac service documentation for your specific regulator model.
