Function  General safety functions
Operating function
- If heat is requested by the boiler
thermostat, 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.

The E-BCU OIL fuel oil control and safety
unit controls and monitors the forced
draught burner. The microprocessor-
controlled program sequence ensures
maximum stability of time periods,
regardless of fluctuations in the power
supply or ambient temperature. The
design of the automatic combustion
control unit protects it from the effects of
brownouts. Whenever the supply voltage
drops below its rated minimum level (170
V), the control unit shuts down - even in
the absence of a malfunction signal. The
control unit switches itself back on again
once the voltage has exceeded the 178 V.

Start up  Adjusting burner output  Oil pressure regulation
Burner start
Before starting the burner, draw oil in until
the filter is completely filled.
Then start the burner by switching on the
boiler regulator. Open the bleed screw on
the oil filter to allow the oil line to bleed
fully during the preventilation phase. The
negative pressure must not fall below 0.4
bar. Close the bleed screw when the filter
is completely filled with oil and oil is
flowing out without bubbles.
Burner output adjustment
Use the pressure regulator to adjust the oil
pressure in accordance with the burner
output desired. Monitor the combustion
values continuously as you do so (CO,
CO2, soot test). Adjust the airflow
gradually if necessary.
Optimising combustion values
If the combustion values are not
satisfactory modify the position of the
combustion head. By doing this the burner
ignition conditions and the combustion
values change. Compensate for the
change in airflow if necessary by adjusting
the air flap position.
Note: observe the minimum required
flue gas temperature specified by the
boiler manufacturer and the
requirements demanded of flue gas

been out of operation for any significant
period of time.
- Starting attempt with flame monitor unlit:
the automatic combustion control unit
must switch to malfunction at the end of
the safety time
- Start with flame monitor lit: the
automatic combustion control unit
must switch to malfunction after 10
seconds of preventilation
- Normal start-up: flame monitor goes out
when burner in operation; the automatic
combustion control unit must switch to

ducts for avoiding condensation.
Oil pressure regulation
The oil pressure, and therefore burner
output, is adjusted using oil pressure
regulator 5in the pump.
Turn to
- right: to increase pressure
- left: to reduce pressure
Connect a pressure gauge at point 3(with
R1/8" thread).
Checking negative pressure
The vacuum meter for checking negative
pressure must be connected to point 4,
R1/8". Maximum permissible negative
pressure is 0.4 bar. At higher negative
pressures, the fuel oil gasifies, which
causes scraping noises in the pump and
ultimately leads to pump damage.
Cleaning the pump filter
The filter is located under the pump
cover(SUNTEC). To be able to clean the
filter, it is necessary to loosen the screws
and remove the cover first (SUNTEC).
• Check the pump cover seal and replace
the gasket if necessary.

Funzione  Funzioni generali di sicurezza
Funzione di esercizio
- In seguito alla richiesta di calore
trasmessa tramite il termostato della
caldaia, il programmatore di comando
(combustione) del gasolio avvia lo
svolgimento del programma.
- Il motore si avvia, l'accensione si
inserisce e si avvia il tempo di
preventilazione di 15 sec.
- Durante la preventilazione, viene
controllata la presenza della fiamma
segnale sul focolare.
- Al termine della preventilazione, si
aprono le elettrovalvole del gasolio e
il bruciatore si avvia.
- Il funzionamento del bruciatore
disinserisce l'accensione.
Disinserimento normale
- Il termostato della caldaia interrompe
la richiesta di calore.
- L'elettrovalvola del gasolio si chiude
e la fiamma si spegne.
- Il motore del bruciatore si spegne
- Il bruciatore è pronto al funzionamento.
Funzione di sicurezza
Uno spegnimento a causa di possibili
disturbi avviene:
- se durante la preventilazione è
presente una fiamma-segnale
(monitoraggio luce esterna);
- se all'accensione (consenso al
combustibile) dopo 5s (tempo di
sicurezza) non si è accesa nessuna
fiamma;
- se, in caso di spegnimento della
fiamma quando l'impianto è in funzione,
dopo un infruttuoso tentativo di riavvio non
si genera alcuna fiamma.
Uno spegnimento in presenza di
eventuali anomalie viene segnalato
mediante accensione della lampadina
di segnalazione guasti e può essere
nuovamente resettato non appena
eliminata la causa del malfunzionamento
e dopo l'azionamento del pulsante di
sblocco.
Per ulteriori informazioni vedere la
descrizione del programmatore di
comando (combustione).
