Zodiac - Base PCB Control Board for PX50 Heat Pump (WH000437) - ZX117250008

Zodiac – Base PCB Control Board for PX50 Heat Pump (WH000437)

This is the genuine Zodiac replacement base PCB (printed circuit board) for the Zodiac PX50 pool heat pump, model reference WH000437. The base PCB is the central control board that manages the unit’s core electrical functions, coordinating the compressor, fan, sensors, and user interface logic to keep the heat pump operating correctly. It corresponds to position 64 in the official Fluidra exploded parts diagram for this model.

Compatibilidad

This base PCB is designed exclusively for the Zodiac PX50 heat pump (parent model WH000437). The PX50 is a Full Inverter pool heat pump covering pools from 35 to 150 m³, with power outputs ranging from 6.3 kW to 24 kW and three operating modes: Boost, Smart, and Ecosilence. Always verify your unit’s model reference before ordering, as PCBs are model-specific and not interchangeable across variants.

Por qué es importante la autenticidad

A faulty or failing base PCB can cause error codes, loss of heating or cooling control, and complete unit shutdown. Using a genuine Zodiac part ensures full electrical compatibility, correct firmware integration, and preserves any remaining warranty on the heat pump. Aftermarket boards may not support the PX50’s Full Inverter variable-speed logic, risking further damage to the unit.

Instalación

Replacement of the base PCB involves working inside the heat pump’s electrical enclosure and should be carried out by a qualified pool heating technician or electrician. Isolate the unit from the mains supply before opening the casing. Refer to the official Fluidra exploded view (position 64) and the WH000437 wiring diagrams to ensure correct connector placement and cable routing.
