Zodiac - Ambient Temperature Sensor for Z250 Heat Pump - 75336R0029

Zodiac – Ambient Temperature Sensor for Z250 Heat Pump

This is the genuine Zodiac replacement ambient temperature sensor for the Zodiac Z250 pool heat pump (WH000555). It monitors outdoor air temperature and feeds real-time data to the heat pump’s control board, enabling the unit’s Full-Inverter system to continuously adjust its output and maintain efficient, accurate pool heating. A faulty or failed sensor can trigger error codes or prevent the heat pump from operating correctly, making like-for-like replacement essential.

Compatibility

This sensor is designed exclusively for the Zodiac Heat Pump Z250 (parent SKU WH000555). It corresponds to position 24 in the official Fluidra exploded-view diagram. Always cross-reference your heat pump’s model number and exploded-view documentation before ordering to confirm fitment.

Why genuine matters

As a genuine Zodiac/Fluidra OEM part, this sensor is manufactured to the precise tolerances required for accurate ambient air temperature readings. Using an authentic replacement ensures seamless integration with the heat pump’s control electronics, preserves reliable performance across the unit’s operating range (down to -7 °C), and helps protect any remaining warranty coverage on the appliance.

Installation

Always disconnect power to the heat pump before beginning any service work. Locate the existing ambient temperature sensor (position 24 on the exploded view), disconnect its wiring harness, and fit the new sensor in its place following the manufacturer’s installation instructions. Restoration of power and a functional check of the unit’s temperature display and operating modes should follow. If you are not a qualified technician, professional installation is strongly recommended.
