Fluidra – Air Temperature Sensor (Red) for Zodiac Z200 R410 Heat Pump

This is the genuine Fluidra replacement air temperature sensor for the Zodiac Z200 R410 pool heat pump series. It monitors ambient air temperature and feeds that data to the control board, enabling the heat pump to optimise heating performance and manage automatic defrost cycles correctly. A faulty or disconnected sensor will trigger an air temperature sensor fault code and prevent normal operation.

Compatibility

This sensor is designed specifically for the Zodiac Z200 R410 heat pump, including MD2, MD3, MD4, and MD5 variants, as well as the compatible PI20 series. It is identified by its red connector for easy and accurate installation on the control board. Always verify your heat pump model and board layout before ordering.

Why Genuine Matters

Using a genuine Fluidra part ensures the sensor’s resistance-temperature curve matches the original specification expected by the control board. An incorrect or third-party sensor can produce inaccurate temperature readings, leading to inefficient heating, repeated fault codes, or improper defrost cycles — potentially causing long-term damage to the compressor.

Installation

The sensor connects directly to the defrost main board inside the heat pump unit. Follow the red connector colour-coding to locate the correct terminal. As this task involves accessing internal electrical components of a heat pump, installation by a qualified pool heating technician is strongly recommended.
