Fluidra - Control & Auxiliary PCB Board Kit A1 + A4 for Zodiac Z300 TD8 Heat Pump

Fluidra – Control & Auxiliary PCB Board Kit A1 + A4 for Zodiac Z300 TD8 Heat Pump

This genuine Fluidra kit contains the A1 regulation (control) PCB and A4 auxiliary circuit board for the Zodiac Z300 TD8 pool heat pump. These electronic boards govern the core operating logic and supplementary functions of the heat pump, and replacing them restores full, reliable performance after electrical faults or component failure.

Compatibility

This kit is designed specifically for the Zodiac Z300 TD8 pool heat pump — a dual-function (heating and cooling) model in the Z300 range. Always verify your Z300 variant and serial number before ordering, as board configurations differ across the M4, M5, M7, MD5, MD8, TD5, and TD8 models. This kit (R07151) is not interchangeable with boards from other variants.

Why Genuine Matters

Using authentic Fluidra replacement boards ensures the control logic, sensor calibration, and safety thresholds all match the original factory specification. Third-party alternatives may not be fully compatible and can compromise compressor protection, defrost cycles, or flow-switch responses — potentially causing further damage to the unit.

Installation

PCB replacement on a pool heat pump involves live electrical components and refrigerant-circuit electronics. Fluidra provides a dedicated board-replacement procedure document (available in English) for this kit. Installation should be carried out by a qualified pool heating technician or electrician familiar with the Z300 platform.
