Application for BCU 570 Burner Control Unit Modulating-controlled forced draught burner

The BCU 570 controls the fan, monitors the combustion media air and gas, controls pre-purge and moves the butterfly valve to pre-purge and ignition position. Once the BCU 570 has started the burner, it issues the enable signal to the external temperature control.
