About This Item
IntellipH® Controller Faceplate and PCB Replacement
The Pentair Faceplate and PCBA (521513) is the OEM replacement faceplate and printed circuit board assembly for the Pentair IntellipH Controller Unit. If your IntellipH display is unresponsive, damaged, or the controller is failing to communicate pH readings accurately, this assembly addresses the core electronic and interface components in a single replacement unit.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
This part contains mains-voltage circuitry. Electrical control components must be installed or replaced by a qualified electrician or certified pool technician. Do not attempt to service this component without proper certification.
The faceplate and printed circuit board assembly serves as the primary user interface and control brain of the IntellipH Controller. The PCBA processes pH sensor input and drives the controller's dosing decisions, while the faceplate provides the physical interface for system status and programming. Failure of either component — whether from moisture ingress, electrical surge, or physical damage — typically presents as a blank or corrupted display, loss of pH control response, or complete controller lockout. Replacing this assembly restores full controller function without requiring replacement of the entire IntellipH unit.

Pro Tip
Before ordering, confirm your IntellipH controller's model number matches 522711. The IntellipH product line includes multiple controller variants, and the PCBA is model-specific. Check the label on the back or base of your controller housing for the model number. If your display is partially functional — showing corrupted characters or intermittent readings — document the symptom pattern before disassembly; this helps your technician confirm the PCBA is the root cause rather than the pH sensor or dosing pump.
