The central unit board is the main electronic control board that manages the operation of a boiler or burner system. It processes signals from sensors and user inputs to regulate functions such as ignition, flame monitoring, and temperature control. This board is critical for the intelligent operation of modern heating equipment. If the central unit board fails, the system may not start or operate erratically. When replacing this component, it is essential to match the board's firmware and hardware configuration to your specific model. A correctly installed central unit board ensures precise control and energy-efficient performance.
