Zodiac - Outlet Water Temperature Sensor - 75311R0075

Zodiac – Outlet Water Temperature Sensor

This genuine Zodiac outlet water temperature sensor (part no. 75311R0075) is an OEM replacement component designed for Zodiac pool heat pumps. It monitors the temperature of water leaving the heat exchanger, enabling the unit to calculate the temperature rise (delta-T) between inlet and outlet and regulate heating operation accurately. A failed or drifting sensor can cause fault codes, erratic cycling, or heating shutdowns — making timely replacement essential.

Compatibility

This sensor is specified for Zodiac heat pump models covered by Fluidra exploded views 77252, 77254, WH000583, WH000585, WH000593, and WH000595, which include models in the Zodiac PX25 heat pump range (MD9, MD12, and related variants). Always cross-reference your unit’s exploded view or service manual before ordering to confirm fitment with your specific model.

Why genuine matters

As an original Zodiac spare part sourced directly through Fluidra, this sensor is manufactured to the exact tolerances required by the heat pump’s control board. Aftermarket sensors may deliver inaccurate readings that trigger false fault codes or prevent the heater from reaching its set temperature.

Installation

Replacement of the outlet water temperature sensor should be carried out by a qualified pool heating technician. The sensor is typically located at the heat exchanger outlet port; the system should be powered down and depressurised before removal. Use PTFE tape on the threads when fitting the new sensor to ensure a watertight seal.
