Zodiac – Control PC Board for Heat Pump PX50 (WH000432)

This is the genuine Zodiac replacement printed circuit board (PC board) for the Zodiac PX50 pool heat pump, model WH000432. The PC board is the central electronic control unit that governs all operational logic of the heat pump, including inverter speed management, operating mode selection, temperature regulation, and error diagnostics. Sourced directly from Fluidra, it is an official OEM spare part and appears at position 60 in the Zodiac PX50 exploded parts diagram.

Compatibilità

This PC board is designed exclusively for the Zodiac Heat Pump PX50 – WH000432. The PX50 range features Full Inverter technology with a rotary compressor and DC fan operating across 10 speeds, three smart operating modes (Boost, Smart, and Ecosilence), and an LCD user interface. Always verify your heat pump’s model number against WH000432 before ordering, as the PX50 range spans multiple variants with different part numbers.

Perché l'originale conta

An original Zodiac PC board ensures full compatibility with the PX50’s Full Inverter control architecture, protecting the compressor, fan motor, and sensor circuits from damage caused by incompatible aftermarket boards. Genuine Fluidra parts maintain the heat pump’s energy-efficiency calibration and preserve any remaining manufacturer warranty. Substituting a non-OEM board risks incorrect speed-range control, fault-code mismatches, and potential premature component failure.

Installazione

Replacement of the PC board involves accessing the electrical enclosure of the heat pump and disconnecting multiple wiring harnesses and ribbon connectors. This work must be carried out by a qualified pool heating technician or electrician familiar with inverter heat pump systems. Always isolate mains power before beginning any work, and consult the official Zodiac PX50 wiring diagram and service manual to ensure correct connector reassembly.
