Lock-out is indicated by a lamp on the control box (4, fig. 1, page 2).

4.7 RE-CYCLE FUNCTION

The control box allows re-cycling, i.e. the complete repetition of the starting programme, for 3 attempts
maximum, in the event the flame goes out during operation.

4.8 POST-VENTILATION FUNCTION

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).
Post-ventilation time can be set to a maximum of 6 minutes. Proceed as follows:
Press and hold the reset button for at least 5 seconds till the LED indicator changes to red.
Set the desired time pressing the button repeatedly: once = post-ventilation for 1 minute.
After 5 seconds the control box automatically shows the minutes set by the red LED flashing:
1 pulse = post-ventilation for 1 minute.
To reset this function, press and hold the button for at least 5 seconds at least, till the LED indicator changes
to red then release it without carrying out any operation, then wait for 20 seconds for the burner to start.
If during post-ventilation there is a new request for heat, post-ventilation time is halted and a new operating
cycle starts when the limit thermostat (TL) switches over.
The control box leaves the factory with the following setting: 0 minutes = no post-ventilation.

4.9 CONTROL BOX RESET

To carry out the control box reset, proceed as follows:
Press the reset button for at least 1 second.
In the event of the burner not restarting it is necessary to check if the limit thermostat (TL) is closed.
