8.1.2 Function LMO14.113
1a.
Operations switch ON, thermostat ON
The burner motor starts, ignition sparks initiated and pre-ventilation
continues until the set pre-ventilation period is over and the
solenoid valve (2) opens.
1b.
Operations switch ON, thermostat ON
The preheater is energized and the pre-heating period begins.
This continues until the operating temperature is reached and the
preheater thermostat closes. The burner motor starts, ignition
sparks initiated and pre-ventilation continues until the set pre-
ventilation period is over and the solenoid valve (2) opens.
2.
Solenoid valve opens
The oil mist is formed and ignited. The photocell indicates fl ame.
The ignition spark ceases 15 sec. after fl ame indication.
3.
a
b
Safety period runs out
If the fl ame is not present before the end of this period, the
oil burner
control blocks further operation.
If the fl ame for any reason disappears after this time period, the
burner will make a new start attempt.
4-5 During operation
If burner operations are interrupted via the main switch or
thermostat, a new start will be initiated when conditions accord-
ing to point 1 are fulfi lled.
Oil burner control blocks
Red light on the oil burner control illuminates. The burner is re-
started by pressing the reset button.
