It initiates the fan operation and positions the connected butterfly valve for pre-purge and ignition. Following pre-purge and burner ignition, it sends an Enable signal to an external controller to adjust the butterfly valve based on output demand. Post-purge occurs once burner operation ceases. Kromschroder 88600015 BCU370WFEU0D1 control unit also monitors gas and air pressure, with an optional tightness control function available to check valves using an external gas pressure switch. Programming via the optical interface and BCSoft PC software ensures optimal adaptation to specific applications. Adjustable start-up attempts and the option for automatic restart enhance burner equipment flexibility. The quick-start feature permits compliant ignition of forced draft burners without pre-purge after regular shutdown, minimizing unnecessary air intake into the combustion chamber. This facilitates rapid availability of heat output upon temperature demand.
