	Forced draught burners Control: On/Off Gas valve and air valve are activated simultaneously. The burner is ignited and monitored by a single electrode. In the event of a flame failure, an immediate fault lock-out occurs.
	Two-stage-controlled burner Control: ON/OFF or ON/HIGH/LOW/OFF The burner BIO/BIC starts at low-fire rate. Once the normal operating state is reached, the automatic burner control unit for continuous operation IFD 258 will release control. The PLC can now pulse the air solenoid valve VR..R in order to control the capacity between high and low fire.
	Modulating-controlled burner Control: ON/OFF/continuous The PLC uses the actuator IC 20 to move the air butterfly valve BVA to ignition position. The burner BIO/BIC starts at low-fire rate. Once the normal operating state is reached, the PLC uses the actuator IC 20 and the air butterfly valve BVA to control the burner capacity.
