Davey – ProMatic MPS 40 & MPS 50 Control PCB (Electronic Board)

This is the genuine Davey replacement printed circuit board (PCB) for the ProMatic MPS 40 and MPS 50 salt water chlorinator systems. The control board is the electronic brain of the unit, managing chlorine output, the patented automatic cell-cleaning cycle, flow monitoring, and all system protections. It is typically replaced when the control unit displays persistent faults, fails to regulate production, or shows signs of electrical failure.

Compatibility

This PCB is designed specifically for the Davey ProMatic MPS 40 and ProMatic MPS 50 salt water pool systems. It is not interchangeable with other ProMatic variants (MPS 16, MPS 24, MPS 36) or with ESR/ESC-series models. Always verify your unit’s model label before ordering to ensure an exact match.

Why Genuine Matters

The ProMatic MPS series relies on a patented automatic electronic cell-cleaning system that demands precisely calibrated firmware and circuitry. A genuine Davey PCB ensures that all protective functions — including low-flow shutdown, low-salt detection, and temperature safeguards — operate exactly as designed. Aftermarket boards risk incompatibility with these proprietary routines and may void your Davey warranty.

Installation

Replacement of the control PCB involves live-voltage components and must be carried out by a qualified electrician or authorised Davey service technician, in accordance with current IEC standards and local electrical regulations. Ensure the installation area is well ventilated and free from chemical fumes, as corrosive vapours can damage the new board and void warranty coverage.
