Davey - ProMatic MPS / ESR / ESC Electronic Control Board (PCB) — ProMatic 16 - M111716EUSP

Davey – ProMatic MPS / ESR / ESC Electronic Control Board (PCB) — ProMatic 16

This is the genuine Davey replacement electronic control board (PCB) for the ProMatic 16 salt water chlorinator — covering MPS 16, ESR 16, and ESC 16 models. The PCB is the brain of the control unit, managing chlorine output levels, LED status indicators, operating modes, and built-in protections against low flow, low temperature, and low salt. It is the part most commonly replaced when the controller displays persistent fault codes, fails to produce chlorine, or shows no response at the panel.

Compatibility

This PCB is designed specifically for the Davey ProMatic 16 series, encompassing the MPS 16, ESR 16, and ESC 16 salt water chlorinator variants manufactured by Monarch Pool Systems by Davey. The ProMatic 16 is sized for residential pools up to approximately 55–80 m³. Always verify your exact model designation and Davey part number (M111716EUSP) before ordering, as PCBs are model-specific and are not interchangeable with other ProMatic sizes (e.g., 24, 36, 48).

Why Genuine Matters

A genuine Davey PCB ensures full compatibility with your chlorinator’s firmware, protection logic, and LED diagnostics — preserving the system’s built-in safeguards for low flow, low salt, and low temperature. Aftermarket boards may not replicate the ProMatic’s precise output calibration or fault-detection thresholds, risking cell damage or unreliable chlorine production. Replacing like-for-like with an OEM board also helps maintain any remaining manufacturer’s warranty on the unit.

Installation

PCB replacement on the ProMatic control unit must be carried out by a qualified pool technician or electrician, in accordance with applicable IEC electrical standards. Before starting, always isolate power to both the controller and the pool pump. Handle the board carefully to avoid electrostatic discharge, and ensure all cable connectors are fully reseated before powering the unit back on.
