The burner control unit QBK [cubic] is suitable for the control of pilot burners up to 350 kW and main burners of unlimited capacity, pursuant to EN 746-2, for intermittent or continuous operation. Flame control by means of UV scanner or ionization rod (even shared with ignition) and high-temperature option for flame surveillance bypass. Specific output for air valve or fan, following cycle or independently controllable. Times and cycle are configurable: the same device can be used to control different types of gas, oil and mixed burners. User interface providing a led-bar flame signal indicator, seven segment status display and reset/shutdown button.
