Fluidra - Equipped Electrical Box Assembly for Zodiac Z400 IQ MD4/MD5 R32 Heat Pump

Fluidra – Equipped Electrical Box Assembly for Zodiac Z400 IQ MD4/MD5 R32 Heat Pump

This is the complete, factory-equipped electrical box assembly for the Zodiac Z400 IQ pool heat pump (MD4 and MD5 variants using R32 refrigerant). It houses and connects the control electronics that manage the heat pump’s operating modes, fan speed, defrost cycle, and integrated Wi-Fi functions. Replacing a faulty or damaged electrical box with this genuine Fluidra unit restores full functionality to the appliance.

Compatibilità

This electrical box is designed specifically for the Zodiac Z400 IQ MD4 and MD5 heat pumps running on R32 refrigerant, corresponding to Fluidra model references WH000382, WH000383, WH000390, WH000391, WH000398, and WH000399. It is not compatible with Z400 R410A variants or the Z400 TD series. Always verify your heat pump’s model label before ordering.

Perché l'originale conta

The Z400 IQ’s electrical box integrates control of multiple systems — including the two-speed fan, automatic defrost, SILENCE mode, and the iAquaLink Wi-Fi module. A genuine Fluidra replacement ensures all these functions operate exactly to the original specification, with correct connector pinouts, protection ratings, and firmware compatibility. Third-party alternatives risk mis-matched interfaces and may void the appliance warranty.

Installazione

Replacement of the electrical box involves working on mains-voltage components inside an appliance that uses R32 refrigerant — a mildly flammable gas. This work must be carried out by a qualified, F-Gas-certified technician. Isolate the heat pump from its power supply before beginning any work, and follow all safety procedures outlined in the Z400 IQ installation and service manual.
