1 .1 .3 Modulating-controlled burner
Control: ON/OFF/continuous
The PLC uses the actuator IC 20 to move the air butter-
fly 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.
