Fluidra - HMI Control Card PCB Assembly for Hydroxinator iQ 10 R

Fluidra – HMI Control Card PCB Assembly for Hydroxinator iQ 10 R

This is the genuine Fluidra replacement HMI (Human-Machine Interface) control card printed circuit board assembly (PCBA) for the Zodiac Hydroxinator iQ 10 R salt chlorinator. It is the electronic board that powers the user-facing control panel — managing display output, button inputs, and communication between the operator interface and the system’s main logic. Replacing a faulty HMI control card restores full control and visibility over your chlorination system.

Compatibility

This control card is designed specifically for the Hydroxinator iQ 10 R, Fluidra’s intelligent MagnaPool mineral electrolysis chlorinator with a nominal chlorine output of 10 g/h, suited to pools up to approximately 40 m³. The Hydroxinator iQ 10 R features a large TFT colour display, multiple operating modes, and Wi-Fi connectivity for remote control via the Fluidra Pool® app — all functions that depend on a correctly operating HMI board. This part is not interchangeable with other Hydroxinator iQ capacity variants (iQ 18, iQ 22, iQ 35) or earlier non-R revisions without confirming compatibility with Fluidra technical support.

Why Genuine Matters

As a safety-critical electronic component in a pool water treatment system, using a genuine Fluidra PCBA ensures the board meets the original IP43 protection rating requirements and is fully compatible with the control box firmware. Counterfeit or third-party boards can cause erratic chlorine dosing, loss of connectivity, or permanent damage to the control box. A genuine part also preserves any remaining manufacturer warranty on the unit.

Installation

Replacement of the HMI control card should be carried out by a qualified pool technician or electrician, as it involves working inside the mains-connected control box. Always isolate the power supply before opening the enclosure. Refer to the Hydroxinator iQ installation and user manual for the correct disassembly procedure and torque specifications for any fasteners.
