Pentair Genuine OEM Replacement UOC Motherboard, 4 Aux, EasyTouch

The Pentair 520659 is the genuine UOC motherboard with four auxiliary circuits for EasyTouch pool and spa automation systems. It is the main board in the load center, the part that drives the relays, reads the sensors and runs every schedule and control function.

When it is the fix

A board that has taken a lightning surge or stopped responding takes the whole system down with it. Replacing the motherboard restores the panel without replacing the load center, relays or transformer, all of which carry over.

Before you order

This is the 4 aux board. Confirm your EasyTouch panel is the four auxiliary version; eight aux systems use a different motherboard.
