The E-BCU GAS fuel gas/LPG control and
safety unit controls and monitors the
forced draught burner. The
microprocessor-controlled program
sequence ensures maximum stability of
time periods, regardless of fluctuations in
the power supply or ambient temperature.
The design of the automatic combustion
control unit protects it from the effects of
R
brownouts. Whenever the supply voltage
drops below its rated minimum level (170
V), the control unit shuts down - even in
the absence of a malfunction signal. The
control unit switches itself back on again
once the voltage has exceeded the 178 V.
