Zodiac – AquaLink Z4 PCBA circuit board replacement kit – R0568200

The Zodiac R0568200 is a factory-replacement PCBA (Printed Circuit Board Assembly) kit designed specifically for the Zodiac AquaLink Z4 pool and spa automation system. This board serves as the central electronic control unit of the Z4 controller, managing communication between the user interface, connected equipment, and the various pool and spa functions the system supervises. When the original PCBA fails due to electrical damage, component wear, or power surge, this replacement kit restores full functionality to the automation system without requiring the replacement of the entire control unit enclosure.

The PCBA is the heart of the AquaLink Z4 — it processes all control logic, receives input signals from sensors and keypads, and outputs switching commands to pumps, heaters, lights, and auxiliary equipment. A faulty circuit board can cause erratic behaviour, loss of communication, or total system shutdown. Replacing the PCBA with the correct OEM part ensures that the repaired system operates exactly as Zodiac designed it, preserving all programming capabilities and equipment compatibility.

Technical characteristics and compatibility

The R0568200 is an OEM Zodiac spare part, meaning it is manufactured to the same specification as the original component installed during production. It is sold as a complete PCBA replacement kit, supplied as shown by Zodiac, and carries the manufacturer part number R0568200. It is also cross-referenced under part number 961079, which may appear on older documentation or packaging.

This board is specifically engineered for the AquaLink Z4 automation system — it is not a universal board and is not intended for use with other AquaLink models unless explicitly confirmed by Zodiac documentation. Because it is a special-order item, lead times are typically 2 to 3 weeks from point of order, which should be factored into any maintenance or repair planning. Installation should be carried out by a qualified pool technician or electrician, as the PCBA is housed within a mains-voltage control enclosure and requires safe handling procedures.

Suitability and application

This replacement kit is intended for pool and spa installations that use the Zodiac AquaLink Z4 automation system. The Z4 is a mid-range automation platform suitable for residential pools and spas of varying sizes, typically controlling equipment such as variable-speed pumps, heaters, lighting circuits, and auxiliary valves. If your AquaLink Z4 controller is displaying fault codes, failing to communicate with connected equipment, or is entirely unresponsive, the PCBA is a primary diagnostic target and this OEM replacement is the correct sourcing solution.

Choosing the genuine Zodiac R0568200 over a generic alternative ensures full compatibility with the Z4 firmware, connectors, and relay layout, reducing the risk of post-repair issues. This product is recommended for service technicians maintaining Zodiac automation installations and for pool owners working with a qualified installer to restore a malfunctioning AquaLink Z4 system.
