It activates the fan and positions the butterfly valve for pre-purge and ignition. After burner startup, it signals an external controller for valve adjustment as needed. Post-purge follows burner shutdown. Kromschroder 88600373 BCU370WI1FEU0D3B1-3 gas burner control box monitors gas and air pressure, with an optional tightness control function for valve monitoring. Programming via optical interface and BCSoft software ensures precise adaptation. Adjustable start-up attempts and automatic restart enhance flexibility. Quick-start allows compliant burner startup without pre-purge, ensuring rapid heat output upon demand.
