COMMISSIONING AND MAINTENANCE
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 (see the “Fault
diagnosis - lockouts” section on page 30).
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
restart.
