Davey - EcoMatic COMM500 Replacement Control PCB - 15797-500SP

Davey – EcoMatic COMM500 Replacement Control PCB

This is the genuine Davey replacement printed circuit board (PCB) for the EcoMatic COMM500 commercial salt water chlorinator — a heavy-duty automatic disinfection system designed for commercial swimming pools. The control PCB is the electronic brain of the power supply unit, managing chlorine production output, LED status indicators, protective shutdowns, and the data communications port. It is typically replaced when the unit displays persistent faults, fails to respond to the production dial, or suffers electrical damage.

Compatibility

This PCB is specific to the Davey EcoMatic COMM500 commercial salt water chlorinator (50 g/h output model). It is not interchangeable with the COMM1000 or any residential EcoSalt/ESC range. Always verify your unit’s model label before ordering. Davey lists this part as available while stock lasts — order promptly to secure a genuine replacement.

Why genuine matters

The EcoMatic COMM500 power supply controls production indicator LEDs, the operation status LED, the production output dial, external ORP/redox input, and the RJ45 data communications port. A genuine Davey PCB ensures these functions operate exactly as designed, preserving the unit’s electronic monitoring of flow, temperature, and conductivity with protective shutdown — critical for a commercial installation. Third-party boards risk mismatched firmware and voided warranty coverage.

Installation

PCB replacement on a commercial chlorinator power supply unit involves live mains voltages and should only be carried out by a qualified electrician or Davey-authorised service technician. Ensure mains power is fully isolated before opening the cabinet. Refer to the EcoMatic COMM500 Installation and Operating Instructions for wiring diagrams and safety precautions.
