Fluidra - pH/ORP Circuit Board Assembly for Control Connect In-Line

Fluidra – pH/ORP Circuit Board Assembly for Control Connect In-Line

This is the genuine Fluidra printed circuit board assembly (PCB assembly) for the Control Connect pH/ORP/Temp in-line pool water treatment controller. It is the core electronic component responsible for processing pH and ORP sensor signals and driving the unit’s monitoring and dosing-control functions. Replacing a faulty board with this genuine part restores full system operation without the need to replace the entire controller.

Compatibility

This PCB assembly is designed specifically for the Fluidra Control Connect pH/ORP/Temp in-line controller (model 71537). The Control Connect in-line range is a wall-mounted, mains-powered system operating at 230 V AC 50/60 Hz with a consumption of 27 W, featuring 4 digital inputs and 4 relay outputs for control of pool equipment such as filtration pumps, dosing pumps, and heating. Always cross-reference your unit’s model number and serial plate before ordering to confirm fitment.

Why Genuine Matters

As the central processing board of the Control Connect system, only a genuine Fluidra replacement guarantees correct calibration ranges, reliable sensor signal interpretation, and full compatibility with the unit’s WiFi connectivity and Fluidra Pool app integration. Third-party boards risk measurement errors, voided warranties, and potential damage to connected dosing pumps or pool equipment. Always disconnect the unit from the mains power supply before replacing any internal component.

Installation

PCB replacement on water treatment control systems involves handling mains-voltage wiring and sensitive electronic connections. Fluidra’s own documentation advises that before installing or replacing any component, the system must be fully disconnected from the power supply, and only genuine manufacturer spare parts should be used. Installation by a qualified pool technician or electrician is strongly recommended.
