Operating function
Safety function
Operating function
- Following the request for heat trans-
mitted through the boiler regulator, the
light oil control (combustion) program-
mer initiates the programme.
- The motor starts, the plant ignites and
the 15-second pre-ventilation time
starts.
- During the pre-ventilation phase, the
presence of the pilot flame on the
brazier is checked.
- At the end of the pre-ventilation
phase, the light oil solenoid valves
open and the burner starts.
- The burner's operation disengages
the ignition.
Normal disengagement
- The boiler's thermostat interrupts the
heat demand.
- The light oil solenoid valve closes and
the flame dies out.
- The burner motor switches off.
- The burner is ready for operation.

Safety function
Switching off due to possible
disturbances can occur in the following
cases:
- if during the pre-ventilation phase a
signal flame appears (external light
monitoring);
- if, during the start-up phase (consent
to fuel), after 5 seconds (safety time) no
flame switches on;
- if, when the flame switches off while
the plant is functioning, after a failed
attempt to restart the appliance, no
flame is generated.
A fault indicator light turns on whenever
the appliance switches off in case of
anomalies, and can be newly reset
once the cause of the malfunction has
been resolved, after pressing the
unblock button.
For further information, consult the
control (combustion) programmer
