Zodiac – Dual pH/ORP module carton – C0299900

The Zodiac C0299900 is a replacement dual pH/ORP module designed for use with Zodiac’s TNG (Tri-Nature Generator) water treatment and control systems. This module is a key spare component that enables the simultaneous monitoring and regulation of both pH levels and ORP (Oxidation-Reduction Potential) within an automated pool water management setup. By measuring these two critical water quality parameters in parallel, the module ensures that pool water remains chemically balanced and safe for swimmers at all times.

pH monitoring controls the acidity or alkalinity of the water, keeping it within the ideal range for swimmer comfort and for the effectiveness of the sanitisation system. ORP measurement reflects the actual oxidising power of the water — a reliable indicator of how effectively the disinfectant is working. Together, these two measurements give the pool controller the data it needs to dose chemicals accurately and automatically.

Technical characteristics and compatibility

The C0299900 module is engineered specifically for the Zodiac TNG product range, ensuring seamless integration with compatible Zodiac controllers and dosing systems. As a dual-channel module, it processes both pH and ORP probe signals within a single unit, reducing wiring complexity and simplifying replacement or maintenance procedures. The carton packaging indicates this is supplied as a retail or service replacement unit, ready for installation by a qualified pool technician or installer.

This module is designed to work in conjunction with Zodiac’s broader range of probes, sensors, and automated dosing pumps, forming part of a fully integrated water treatment system. Precise signal processing allows the controller to respond quickly to any drift in water chemistry, triggering dosing pumps as required to maintain target values. This level of automation reduces manual testing and chemical overdosing, extending equipment life and improving water quality consistency.

Suitability and application

The Zodiac C0299900 dual pH/ORP module is intended for use with Zodiac TNG automated pool control systems installed in residential and light commercial swimming pools. It is specifically suited to pools where automated chemical dosing is in place and where both pH and ORP need to be monitored continuously. This product is a direct replacement spare part and is not a standalone device — it must be installed into a compatible Zodiac TNG control unit. It is recommended for situations where the existing module has developed a fault, requires servicing, or needs to be replaced as part of a scheduled maintenance programme. Always verify compatibility with your specific Zodiac controller model before ordering.
