This is the genuine Davey replacement printed circuit board (PCB) for the EcoMatic COMM500 commercial salt water chlorinator \u2014 a heavy-duty automatic disinfection system designed for commercial swimming pools.

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.

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 \u2014 critical for a commercial installation. Third-party boards risk mismatched firmware and voided warranty coverage.<\/p>\n
