Zodiac – Hygro/temperature sensor for regulation box – B0201900A

The Zodiac B0201900A is a replacement hygro/temperature sensor designed for use with Zodiac regulation boxes. This sensor performs a dual function: it continuously monitors both the relative humidity and the ambient temperature inside the technical enclosure or equipment housing. The data it collects is fed directly to the regulation box, which uses this information to manage and protect the pool equipment from condensation, moisture damage, and thermal stress. As a genuine Zodiac spare part, it is engineered to exact OEM specifications, ensuring reliable performance and precise measurement within the system it was designed for.

The sensor integrates seamlessly with the regulation box electronics, providing real-time environmental feedback that allows the control system to activate ventilation, heating, or protective routines as required. The combined hygrometric and temperature measurement capability in a single compact unit simplifies installation and reduces wiring complexity. It is a direct replacement component, meaning no modification or adaptation is required when fitting it into a compatible Zodiac regulation box.

Technical characteristics and compatibility

As a Zodiac OEM component, the B0201900A sensor is specifically calibrated for the Zodiac regulation box environment. The hygro/temperature sensor is a combined sensing element, measuring both ambient relative humidity levels and temperature simultaneously. This dual sensing approach ensures the regulation box receives accurate, correlated environmental data rather than relying on two separate independent sensors, which improves system response accuracy.

The sensor is designed for indoor or sheltered technical enclosure use — typically installed inside pool equipment cabinets, plant rooms, or regulation box housings where moisture ingress and temperature fluctuations can affect sensitive electronics. Its compact form factor allows straightforward fitment within the existing housing without modification. As a genuine Zodiac part, it is built to the same tolerances and operating parameters as the original component it replaces, which is critical for maintaining the accuracy and reliability of the overall regulation system.

Suitability and application

This sensor is intended for pool owners, pool technicians, and maintenance professionals who need to restore the correct environmental monitoring function of a Zodiac regulation box. It is not a universal third-party sensor — it is a purpose-specific Zodiac replacement component and should be selected only for systems that originally used this part. It is suitable for use across pool installations where a Zodiac regulation box is employed as part of the pool equipment control infrastructure, including residential and light commercial pool setups.

If the original sensor has failed, is giving inaccurate readings, or has been physically damaged, replacing it with the genuine B0201900A ensures that the regulation box continues to operate as designed, protecting the pool equipment from humidity and temperature-related faults. Always verify compatibility with your specific Zodiac regulation box model before ordering.
