Function
- General safety functions
Light oil pre-heating
(version R)
If the system demands heat, the pre-
heater is switched on first.
When the oil preheating temperature is
reached, a thermostat in the pre-heater
activates the program sequence.
The heating time with cold start is
approximately 1 minutes.
Operating function
- If heat is requested by the boiler
regulator, the automatic oil combustion
control unit starts the program
sequence.
- The motor starts, the igniter is switched
on and the preventilation period of 15
seconds commences.
- During the preventilation period, the
furnace is monitored for flame signals.
- At the end of the preventilation period,
the fuel-oil solenoid valve opens and the
burner starts.
- The igniter remains switched off while
the burner is in operation.
Controlled shutdown
- Boiler thermostat interrupts heat
request.
- The fuel-oil solenoid valve closes and
the flame is extinguished.
- Burner motor switches off.
- Burner enters standby.
Safety function
A safety shutdown occurs:
- if a flame signal is present during
preventilation (parasitic flame
monitoring).
- if no flame is produced within 5 seconds
(safety time) of start-up (fuel
authorisation).
- if no flame is produced after an
unsuccessful restart attempt in the
event of flame failure during operation.
A safety shutdown is indicated by the
malfunction lamp lighting up and it is then
only possible to reenable the burner by
pressing the reset button after the cause
of the malfunction has been rectified.

automatic combustion control unit
description.
