PRE-HEATING FUNCTION
The burner controller has a fuel oil pre-heating function. In the pre-heating phase, the burner waits for the startup ther-
mostat, located at the nozzle holder, to close.
If the thermostat has not closed after 600 seconds, the burner controller locks out.
If the flame goes out during normal functioning, the controller checks whether the pre-heating startup contacts are closed
of not. If the contacts are open, the burner remains in wait state. The burner re-ignites when the contacts close.
SHUTDOWN TEST
If the reset or remote reset button is pressed and held down for a time between 5 and 10 seconds during normal functio-
ning, the burner shuts down, the fuel oil valve closes, the flame goes out and then the startup sequence starts.
If the shutdown test is enabled, the current number and maximum number of startup sequence repetitions are zeroed.
CONTROLLED SHUTDOWN AND RESTART
After a maximum of 24 hours continuous functioning, the controller initiates an automatic shutdown sequence followed
by a re-start. You can reduce this automatic shutdown time to 1 hour (see "Programming Mode") in order to test the flame
detector for possible malfunctions.
RECYCLING AND THE STARTUP SEQUENCE REPETITION LIMIT
The burner controller has a recycling function. This means that the controller will repeat the complete startup sequence
up to 3 times if the flame goes out during normal functioning.
If the flame goes out 4 times, the burner controller enters lockout. If the burner controller receives a new heat request
during the recycling process, the total of 3 attempts is restored when the maximum temperature thermostat (TL) trips.
Note: If the burner functions continuously for 510 seconds, the controller is allowed one additional startup attempt .
Disconnect and reconnect power to the burner to obtain a further complete series of startup attempts (max. 3) for the
next heat request.
PRESENCE OF EXTRANEOUS LIGHT
If extraneous light is detected for longer than 25 seconds, the burner controller enters lockout.
By resetting the burner controller, you obtain a further startup attempt when the next heat request is received (the burner
must be switched on).
PRE AND POST-IGNITION
During pre-ignition, the ignition electrode switches on 2 seconds before the fuel oil valve opens.
During post-ignition, the ignition electrode switches off 3 seconds after the end of safety time.
The ignition electrode remains on throughout safety time.
Note: If the startup sequence repeats continuously, ignition attempts cannot be more frequent than one a minute .
POWER SUPPLY FREQUENCY ERROR
The burner controller automatically detects the frequency of the main power supply over the interval of 50 to 60 Hz.
Operating times are verified for both frequencies.
An error is indicated by the LED flashing.
- If an error is detected before a heat request is received, the burner will not start up. (The burner waits until the error
disappears.).
- If an error is detected after a heat request has been received, the burner waits in ventilation mode.
- If an error is detected during normal functioning, the burner continues to function normally.
FAN MOTOR CONTROL
The burner controller automatically monitors the functioning of the fan motor and enters lockout in the event of a fan
motor failure.
FUEL OIL VALVE CONTROL
The burner controller automatically detects the presence of the fuel oil valve solenoid and enters lockout in the event of
a fuel oil valve solenoid failure.
