	Modulating-controlled burner Control: ON/OFF/Continuous The external control system moves the butterfly valve for air to ignition position. The burner starts at low-fire rate, and a regulator controls the burner capacity via the butterfly valve for air after the operating state has been signalled.
	Two-stage-controlled burner ("L" products) Control: ON/OFF or ON/HIGH/LOW/OFF The BCU supports the cooling and purging processes. The burner starts at low-fire rate. When the operating status is reached the BCU advises the control unit. The PLC can now pulse the air valve in order to control the burner capacity.
	Single-stage-controlled radiant tube burner ("L" products) Control: ON/OFF The BCU supports the cooling and purging processes.
