About This Item
The Pentair Motherboard 8 Aux Single Body (520711) is the OEM replacement circuit board for the EasyTouch Automatic Control System single-body configuration, providing up to 8-auxiliary circuit control.
⚠️ IMPORTANT: ELECTRICAL CONTROL COMPONENT — LICENSED PROFESSIONAL INSTALLATION REQUIRED
This motherboard operates at mains voltage (120V/240V). Installation or replacement must be performed by a qualified electrician or certified pool technician. Do not attempt to service this component without proper certification.
The motherboard is the central processing unit of the EasyTouch single-body control system, managing all automated pool and spa functions across up to 8 auxiliary circuits — including pumps, lighting, heaters, and accessory equipment. When the motherboard fails, the entire control system loses the ability to execute scheduled operations, respond to sensor inputs, or communicate with connected devices. Replacing this board with the correct OEM part restores full system functionality without requiring a complete controller replacement.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.
Pro Tip
Before ordering, confirm your EasyTouch system is the single-body configuration — the dual-body version (separate pool and spa control) requires a different motherboard. The configuration type is printed on the inside of your EasyTouch enclosure door or in the system's installation manual. Also note the auxiliary count on your existing board: this listing is specific to the 8-auxiliary version. Matching the part number stamped on your original board to 520711 is the most reliable verification step before purchase.
