AstralPool – Electronic Control Card D300+ V1 for Salt Electrolysis & pH Control D-65/300 EX/Plus

This is the genuine AstralPool Electronic Control Card (V1) for the Salt Electrolysis and pH Control D-65/300 EX/Plus system — the main PCB responsible for managing electrolysis output, pH/ORP dosing logic, alarm handling, and operator display functions. It occupies position 2 in the official Fluidra exploded view diagram for this unit and is the authoritative replacement board for restoring full system operation.

Kompatibilität

This electronic card is designed exclusively for the AstralPool Salt Electrolysis and pH Control D-65/300 EX/Plus range, covering parent SKUs 35259, 35260, 35261, and 35262 (D-65, D-120, D-180, and D-300 Plus models). Always verify your unit’s model number and exploded view position before ordering, as control cards are model-specific and not interchangeable across different product families.

Warum Echtheit zählt

As the nerve centre of the electrolysis and pH control system, the electronic card governs chlorine production levels, automatic ORP/pH dosing, safety alarms, and the backlighted LCD interface. Using a genuine AstralPool replacement ensures full electrical compatibility, correct firmware behaviour, and preserved warranty integrity — critical in a system responsible for commercial or residential pool water safety.

Installation

Replacement of the electronic control card involves working inside a live electrical enclosure and should be carried out by a qualified pool technician or electrician. Power must be fully isolated before opening the unit. Refer to the official Fluidra exploded view (position 2) and service documentation for your specific D-65/300 EX/Plus model SKU to ensure correct fitment and reassembly.
