Lockout types and triggering times in case of burner malfunction

DESCRIPTION OF THE FAULT TYPES
Extraneous light when the burner is turned on and off
Presence of extraneous light during standby time
Extraneous light detected during pre-purging
Extraneous light detected during post-purging or continuous purging (*)
Flame goes out during operation
No flame is detected after safety time
(*) only for suitable applications.

Control box reset

To carry out the control box reset, proceed as follows:
 Press and hold the reset button for 1-2 seconds. In the
event of the burner not restarting 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.
If the reset button is pressed for more than 2 sec-
onds, the control box goes into visual diagnostic
mode and the signalling LED begins to blink (see
WARNING 'Visual diagnostics of the control box" page 26).

Recycle function

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
lockout of the burner. If there is a new heat request during the re-
cycle, the 3 attempts are restored to the switch-over of the limit
thermostat (TL).

Logging of burner operating parameters

With this control box, data - i.e. the number of lockout that have
occurred, the type of lockout that has occurred (just the last one)
and the oil valve opening operating time - can be logged even
when there is no power supply.
In this way it is possible to establish how much fuel has been con-
sumed during the operation.
To visualise these parameters it is necessary to connect the soft-
ware diagnostic kit, as described in the paragraph "Software di-
agnostics kit".

Post-ventilation is a function that maintains air ventilation even
after the burner is switched off.
The burner switches off when the limit thermostat (TL) opens,
cutting off the fuel supply to the valves.
To use this function the reset button must be pressed when the
limit thermostat is not switched over (burner switched off).
The post-purging time can be set for a maximum of 6 minutes,
proceeding as follows:
 press the reset button for at least 5 seconds, until the sig-

To reset this function, just press the button for 5 seconds until the
signalling LED turns to red, then release it without carrying out
any operation. Wait at least 20 seconds before restarting the
burner.
If during post-purging there is a new request for heat, post-purg-
ing time is halted and a new burner operating cycle starts when
the limit thermostat (TL) switches.
If during post-purging there is an extraneous light the burner
blocks after thirty seconds.
The control box leaves the factory with the following setting:
0 blinks = no post-purging.
