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 sec-
onds.
After releasing the button, the GREEN LED starts flashing as shown in the figure below.
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:
ACCESSORIES
(optional):
•
RADIO DISTURBANCEPROTECTION KIT
If the burner is installed in places particularly subject to radio disturbance (emission of signals exceeding 10 V/m) owing to the presence of an
INVERTER, or in applications where the length of the thermostat connections exceeds 20 metres, a protection kit is available as an interface
between the control box and the burner.
•
OUTPUT POWER REGULATOR KIT:
Under modulating operation, the burner automatically adapts to one of an infinite number of firing rates between the low and high flame output
position, thus ensuring stable operating conditions in terms of temperature or pressure.
Two components should be ordered: • Power regulator to install to the burner; • probe to install to the boiler).
•
