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 88600047 BCU370WI1FEU0D1 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.
