Zodiac - Ambient Temperature Sensor for Pool Heat Pumps - 75311R0523

Zodiac – Ambient Temperature Sensor for Pool Heat Pumps

This is a genuine Zodiac OEM ambient temperature sensor (part number 75311R0523), designed as a direct replacement for Zodiac pool heat pumps. The sensor continuously monitors outdoor air temperature, feeding real-time data to the heat pump’s control board to regulate heating and cooling cycles efficiently and safely.

A faulty or disconnected ambient temperature sensor can trigger fault codes and cause the heat pump to stop operating. Replacing it with this original Zodiac part restores accurate temperature monitoring and ensures the unit functions correctly in all operating modes, including automatic heating, cooling, and defrost cycles.

Compatibility

This sensor is compatible with Zodiac and Fluidra heat pump models covered by exploded views 77252, 77254, WH000583, WH000585, WH000593, and WH000595, which include models from the Zodiac iQ and PX series heat pump ranges. Always cross-reference your heat pump’s model number and exploded view code before ordering to confirm fitment.

Why genuine matters

As an original Zodiac spare part, this sensor is manufactured to exact factory tolerances, ensuring precise temperature readings and full compatibility with your heat pump’s control electronics. Aftermarket sensors may not match the required resistance characteristics, leading to inaccurate readings, nuisance faults, or inefficient operation.

Installation

Replacement of the ambient temperature sensor should be carried out by a qualified pool heating technician. The sensor must be correctly positioned to read ambient air temperature accurately — away from direct sunlight and heat sources — and securely connected to the control board wiring harness. Always isolate the heat pump from the power supply before commencing work.
