Fluidra - Main Control PCB Assembly for Ei2 iQ 20 Salt Chlorinator

Fluidra – Main Control PCB Assembly for Ei2 iQ 20 Salt Chlorinator

This is the genuine Fluidra replacement main control circuit board (PCB assembly, LC2 variant) for the Zodiac Ei2 iQ 20 salt chlorinator. It is the brain of the unit, managing chlorine production levels, safety cut-outs, electrode polarity reversal, and communication with the Fluidra Pool app via Wi-Fi and Bluetooth. Replacing a faulty board restores full automated operation of your salt electrolysis system.

Compatibility

This control board is designed specifically for the Fluidra Zodiac Ei2 iQ 20 salt chlorinator — the connected model rated for pools up to 90 m³ with a maximum chlorine output of 20 g/h. It is not interchangeable with other Ei2 variants (12 g/h or 25 g/h) or pH evo models without confirmation from Fluidra technical support. Always verify your unit’s model label before ordering.

Why Genuine Matters

The Ei2 iQ 20 control board governs critical safety functions including flow detection, automatic electrode cleaning cycles, and overvoltage protection. Using a genuine Fluidra part ensures these protections remain fully active, preserves any remaining manufacturer warranty, and guarantees precise compatibility with the unit’s firmware and connectivity features.

Installation

PCB replacement on salt chlorinator control units involves mains voltage and must be carried out by a qualified electrician or trained pool technician. The power supply must be fully isolated before opening the enclosure. Refer to the official Ei2 iQ user manual and follow all applicable IEC electrical safety standards throughout the procedure.
