Davey - ProMatic 24 Electronic Control PCB (MPS / ESR / ESC) - M111724EUSP

Davey – ProMatic 24 Electronic Control PCB (MPS / ESR / ESC)

This is the genuine Davey replacement printed circuit board (PCB) for the ProMatic 24 salt water chlorinator controller. The PCB is the brain of the control unit, managing chlorine production levels, cell protection logic, timing, and safety cut-outs. It is the correct replacement when the existing board has failed due to age, moisture ingress, chemical vapour corrosion, or electrical fault.

Compatibility

This PCB is designed for the Davey ProMatic 24 controller unit, covering the MPS, ESR, and ESC series variants of the ProMatic range. The ProMatic is a salt water chlorinator suited to residential pools, and the 24 designation refers to the chlorine output capacity of the unit. Always verify your exact ProMatic model and controller housing type before ordering to confirm fitment.

Why Genuine Matters

The ProMatic control unit houses sensitive electronics that regulate electrolysis cell output, low-salt protection, low-flow cut-out, and pool cover interlock signals. A genuine Davey PCB ensures all these safety and performance functions operate exactly as designed, maintaining warranty compliance and protecting the electrolysis cell from premature wear. Non-genuine boards risk incompatibility with the unit’s firmware and protection circuitry.

Installation

PCB replacement involves live mains-voltage wiring inside the control enclosure and must be carried out by a qualified electrician or authorised Davey service technician. The control unit must be fully isolated from the power supply before any work begins. Ensure the installation area is well ventilated and free from chemical vapours, as acid and chlorine fumes are a known cause of PCB corrosion.
