Pentair EasyTouch UOC Motherboard w/ 4 Auxiliaries | 520659
The Pentair EasyTouch UOC Motherboard with 4 Auxiliaries (520659) is a replacement controller board for the Pentair EasyTouch Automation System. As the central logic hub of an EasyTouch panel, this motherboard provides the main processing and communication functions that allow your system to run schedules, control pumps, heaters, lights, and other auxiliary circuits, and respond with timing logic through the automation interface.

This motherboard with 4 auxiliary outputs is designed specifically for the Pentair EasyTouch Automation System.
