Jandy AquaLink RS4 Upgrade Kit

Yes, this kit is specifically designed to retrofit existing AquaLink RS4 systems. It is intended to bring older hardware up to current standards without requiring a complete system replacement.

The primary benefit is expanded compatibility. Once installed, your system will be able to communicate with modern variable speed pumps and advanced LED lighting systems that older firmware versions could not support.

While the kit includes all necessary hardware like the CPU board, chip, and bezel, it involves working with your pool's electrical control system. If you are comfortable with basic electrical troubleshooting and board replacement, it is manageable, but we recommend hiring a pool technician if you are unsure.

Yes, this upgrade enables support for remote panel integration. Once the firmware is updated to Version QQ, you can interface with newer remote control options that were previously incompatible with your older system.

No, this is a retrofit package. You will replace the internal components—specifically the CPU board and chip—and the bezel, but the existing wall-mounted enclosure remains in place.
