Operating mode
Oil firing, three stage
If no flame is present after the startup safety period has elapsed, the burner
enters the non-variable fault state.
If flame failure occurs while the burner is operating, a fault shut-down takes
place and the system executes a restart. If the presence of a flame is not
signalled, the system enters the non-variable fault state.
In the event of a fault shut-down, all valves are closed and the blower and
ignition are turned off.
If the presence of a flame is signalled before the gas is enabled, the automatic
burner control enters the non-variable fault state.
The type of fault or disturbance is displayed.
If air pressure switch failure is detected during the startup period, provided the
watchdog function is activated, a safety shut-down takes place and 5 restart
attempts are performed; if this occurs when the burner is operating, the
automatic burner control enters the non-variable fault state.
If the oil pressure drops, the automatic burner control enters the non-variable
fault state.
