Control box reset
6.6.1
Reset using built-in button
To carry out the control box reset, proceed as follows:
Press and hold the reset button for 1-2 seconds.
In case the burner does not restart it is necessary to check if
the limit thermostat (TL) is closed.
If the control box reset button continues to blink, signalling
the cause of the failure (red LED), it is necessary to press
the button again for no more than 2 seconds.
6.6.2
Reset using remote connection
An accessory connection is provided for the remote reset of the
control box.
6.6.3
Colour code of the control box reset button

6.7
Recycle function (in the event of flame disappearance during operation)
The control box allows recycling, i.e. the complete repetition of
the starting programme, for 3 attempts maximum, in the event the
flame goes out during operation.
The further disappearance of the flame (4
th
time) determines the
lockout of the burner.
If there is a new heat request during the recycle, the 3 attempts
are restored to the switch-over of the limit thermostat (TL).
6.8
Logging of burner operating parameters
The control box allows the logging (even without the electrical
power supply) of the number of lockouts that have occurred, the
type of lockout that has occurred (only the last one) and the op-
erating time of the opening of the oil valve.
That way, you can determine how much fuel has been consumed
during operation.
For the display of these parameters it is necessary to connect the
diagnostic software kit.
