Zodiac - High Pressure Sensor for Z900 Heat Pump - R07791

Zodiac – High Pressure Sensor for Z900 Heat Pump

This is the genuine Zodiac replacement high pressure sensor (SKU R07791) for the Z900 commercial heat pump series. It monitors refrigerant pressure within the cooling circuit and feeds critical data to the unit’s control system, protecting the compressor from operating outside safe pressure limits.

Compatibility

This sensor is a direct OEM replacement for the Zodiac Z900 TD20 (WH000270), Z900 TD30 (WH000271), and Z900 TD50 (WH000272) heat pumps — the full range of Z900 standard models designed for large commercial and semi-commercial pools. Always cross-reference your unit’s exploded view diagram before ordering to confirm fitment.

Why genuine matters

As a safety-critical component in the refrigerant circuit, using a genuine Zodiac part ensures accurate pressure readings, correct electrical compatibility with the Z900 control board, and compliance with the unit’s original design tolerances. Non-OEM sensors risk false trips, undetected faults, or compressor damage in this high-capacity heat pump.

Installation

Replacement of a high pressure sensor in a refrigerant circuit must be carried out by a qualified refrigeration or HVAC technician, as it involves working within a closed cooling system. Always isolate and depressurise the circuit before beginning work, in line with Zodiac’s service guidelines for the Z900.
