Fluidra - Coil Temperature Sensor for Z650iQ Heat Pump

Fluidra – Coil Temperature Sensor for Z650iQ Heat Pump

This is the genuine Fluidra replacement coil temperature sensor for the Zodiac Z650iQ MD8 pool heat pump. Mounted directly on the refrigerant coil, it continuously monitors coil temperature and relays readings to the heat pump’s control board, allowing the unit to regulate its inverter compressor, protect against overheating, and maintain peak efficiency.

Compatibility

This sensor is designed specifically for the Zodiac / Fluidra Z650iQ MD8 full-inverter pool heat pump. If you own a different Z650iQ variant (e.g. MD4, MD5, MD6, MD10, TD series), please verify the part number before ordering, as coil sensor specifications may differ between models.

Why Genuine Matters

The Z650iQ’s Full Inverter control system relies on precise, real-time coil temperature data to switch between its Boost, Smart, Ecosilence and Smart+ operating modes. A genuine Fluidra sensor ensures the correct resistance characteristics and connector fit, so the control board receives accurate readings — keeping your heat pump running safely and maintaining its energy efficiency rating of ‘A’ under EN 17645.

Installation

Replacing the coil temperature sensor requires accessing the internal refrigerant circuit housing of the heat pump. We recommend this work be carried out by a qualified pool heating technician or F-gas engineer. Ensure the unit is fully powered down and isolated before beginning any disassembly.
