INTERNAL VOLTAGE ERROR
The burner controller automatically checks that internal voltage is correct. An error is indicated by the LED flashing.
- If an error is detected during initialisation, make sure that it is transient and that the burner starts 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.
The burner starts up as soon as the error disappears.
RESET / REMOTE RESET BUTTON FAULT
If the reset button or remote reset button sticks in pressed position for more than 60 seconds, the LED flashes to indicate
an error.
- If an error is detected during pre-ventilation or safety time, the burner does not enter lockout but continues with the
startup sequence.
- If an error is detected during normal functioning, the burner continues to function normally.
- If an error is detected during a lockout, it is ignored.
The LED stops flashing as soon as the error disappears.
EEPROM CONTROL
The burner controller automatically checks for errors in the microcontroller EEPROM and enters lockout if an error is
detected.
An error is indicated by the LED flashing.
PUMP PRIMING FUNCTION
During a lockout, the burner can be purged for 30 seconds to eliminate any air from the pipes and filters of the fuel oil
supply pipes.
To avoid damaging the pump, do not repeat this procedure more than 5 times.
