COMMISSIONING AND MAINTENANCE
POWER SUPPLY FREQUENCY ERROR
The control box automatically detects the value of the frequen-
cy of the main supply in the range of 50 - 60 Hz, in both cases
working times are verified. The fault is indicated by the flashing
of the LED (see paragraph "Fault diagnosis - lockouts" on page
54).
− If an error is detected before a heat request is made, the
burner does not start up and the error is signalled.
− If an error is detected during pre-purging, the burner re-
mains in purge mode and the error is signalled.
− If no error is detected during normal functioning, the
burner continues to function normally.
− The burner starts up as soon as the error disappears.
INTERNAL VOLTAGE ERROR
The control box automatically detects if the internal voltage
works correctly. The fault is indicated by the flashing of the LED
(see paragraph "Fault diagnosis - lockouts" on page 54).
− If an error is detected during initialisation, the burner
does not start up.
− If an error is detected after a lockout, the burner will not
start up.
− If an error is detected after a shutdown test, the burner
will not start up.
− If no error is detected during normal functioning, the
burner continues to function normally.
− The burner starts up as soon as the error disappears.
FAN MOTOR CONTROL
The control box automatically detects the presence of the fan
motor and, if it is disconnected, it performs a lockout.
The lockout is indicated by the flashing of the LED (see paragraph
"Fault diagnosis - lockouts" on page 54).
CHECKING THE LIGHT OIL VALVE CONTROL ELECTRONIC CIRCUIT
The control box detects the presence of an internal light oil fault,
the fault is indicated by the blinking led. (see paragraph "Fault
diagnosis - lockouts" on page 54):
− If the anomaly is detected during the initialisation, the
burner goes into lockout.
− If the anomaly is detected during the pre-purging, the
burner goes into lockout.
− During a recycling, if the fault is detected, the burner
does not start and goes into lockout.
− If no error is detected during normal functioning, the
burner continues to function normally.
The fault is not detected if the burner is in lockout.
EEPROM CHECK
The burner controller automatically checks for errors in the mi-
crocontroller EEPROM and enters lockout if an error is detected.
The lockout is indicated by the flashing of the LED (see paragraph
"Fault diagnosis - lockouts" on page 54).
DEACTIVATION OF AUTOMATIC PRE-HEATING
The automatic pre-heating functioning can be deactivated by
pressing the reset or remote reset button.
Pre-heating remains de-activated until:
− a lockout occurs;
− mains power fails or is switched off;
− the boiler shuts down for a controlled shutdown and re-
start.
Pre-heating de-activation sequence
Colour of button
LED
Only de-activate the pre-heating if no
lockout or errors are present
-
Deactivate the pre-heating by means of
the reset or remote reset button.
-
Switch on the burner and simultane-
ously hold down the reset or remote
reset button for 3 seconds.
RED
Release the reset or remote reset button
within 3 seconds.
OFF
The burner will de-activate pre-heating
only if the reset or remote reset button is
released within 3 seconds.
-
The deactivation of the automatic pre-heating function is not
lost if the switching off test function is active or if the heat re-
quest thermostat opens.
POST-PURGING
The post-purging function keeps the fan running for a set time
after the burner shuts down provided there is no new heat re-
quest.
When the contacts of the heat request thermostat open, the
burner controller shuts down the flame and shuts off the oil
supply.
Post-purging does not occur:
− after a lockout;
− if a heat request is cancelled during pre-purging.
Post-purging occurs:
− if a heat request is cancelled during safety time;
− if a heat request is cancelled during normal functioning.
NOTE
If extraneous light or a false flame signal is detected during
post-purging, the burner locks out after 25 seconds.
If a new heat request is detected during post-purging,
post-purging time is reset, the fan motor stops and a new
burner ignition cycle is initiated.
PROGRAMMING MENU
General
The programming menu can be accessed via the integrated reset
button during OPERATION and in STAND-BY.
If in the menu page the reset button is not pressed within 10
seconds, the page will be automatically quitted and a green led
will start flashing for the time set.
If the number of presses on the reset button exceeds the max-
imum allowable, the value that stays in memory will be the
maximum one.
If the reset button is pressed for more than 60 seconds, a button
error will be displayed and the control box will restart.
