NORMAL OPERATION / FLAME DETECTION TIME
The control box has a further function to guarantee the correct burner operation (signal: GREEN LED permanently on).
To use this function, wait at least ten seconds from the burner ignition and then press the control box button for a minimum of 3 seconds.
After releasing the button, the GREEN LED starts flashing as shown in the figure below.

wait at least 10s
The pulses of the LED constitute a signal spaced by approximately 3 seconds.
The number of pulses will measure the probe DETECTION TIME since the opening of gas valves, according to the following table:

43 - The gas pressure in the gas mains lies very close
to the value to which the minimum gas pressure
switch has been set. The sudden drop in pres-
sure after valve opening causes temporary open-
ing of the pressure switch itself, the valve
immediately closes and the burner comes to a
halt. Pressure increases again, the pressure
switch closes again and the ignition cycle is
repeated. And so on
