The Pentair 520818 is a specialized Serial COM Port Expansion Module designed to increase the communication capacity of IntelliTouch and EasyTouch pool and spa automation systems. This printed circuit board assembly (PCBA) acts as an essential bridge, adding multiple RS-485 communication ports to a system that has already reached its standard port limit. By installing this module, pool owners can integrate a wider range of high-performance accessories—such as IntelliFlo variable speed pumps, IntelliChlor salt systems, heaters, and ScreenLogic2 protocol adapters—directly into their existing automation network. The kit is also a key component for upgrading legacy ComPool systems to modern EasyTouch functionality, ensuring stable data transmission across all connected backyard devices.
