The Zodiac R0568500 is a genuine OEM air temperature sensor designed as a direct replacement component for the Zodiac AquaLink Z4 pool and spa automation system. This sensor monitors ambient air temperature and feeds real-time data to the AquaLink Z4 control unit, allowing the system to make accurate, automatic decisions about heating, filtration scheduling, and overall pool management. As a manufacturer-original spare part, it is engineered to the exact specifications of the original sensor supplied with the AquaLink Z4, ensuring full compatibility and reliable performance without the need for adjustments or workarounds.

The sensor comes supplied in its original unopened bag, preserving component integrity until installation. It is a plug-and-play replacement that connects directly to the AquaLink Z4 control board, making the swap straightforward for a qualified pool technician or experienced installer. The part is part of the broader Zodiac AquaLink Z4 sensor family and works in conjunction with the system’s water temperature sensor to provide complete environmental monitoring for automated pool and spa control.

Technical characteristics and compatibility

The R0568500 air temperature sensor is specifically designed for use with the Zodiac AquaLink Z4 automation system. The AquaLink Z4 is a compact, entry-level pool automation controller that manages the key functions of a pool installation including pump control, lighting, and heating. The air temperature sensor plays a critical role in this ecosystem by providing the controller with accurate ambient temperature readings, which are essential for optimising heating efficiency and maintaining comfortable water conditions relative to outdoor conditions.

As a genuine Zodiac spare part, the R0568500 is manufactured to the same tolerances and material standards as the original component. It is important to note that this product has been listed as discontinued by Zodiac Pool Systems, meaning availability may be limited to existing stock. Buyers are advised to source this part promptly if their AquaLink Z4 system requires a sensor replacement, as new old stock units represent the remaining supply.

Suitability and buying context

This air temperature sensor is intended exclusively for pool and spa installations controlled by the Zodiac AquaLink Z4 automation system. It is not compatible with other AquaLink models or third-party controllers. If your AquaLink Z4 is displaying incorrect air temperature readings, triggering false alarms, or failing to respond correctly to ambient temperature conditions, replacing the air temperature sensor with this genuine Zodiac part is the recommended first step in restoring accurate system operation.

This product is suited to residential pool installations of all sizes that are managed via the AquaLink Z4 platform. Given its discontinued status, it is particularly valuable for owners maintaining older AquaLink Z4 systems who require a like-for-like OEM replacement rather than an aftermarket alternative. Installation should be carried out by a qualified pool technician familiar with Zodiac AquaLink systems to ensure correct wiring and calibration.
