There are faults that cause permanent shutdown (marked with the letter “A”): to restore operation, press the RESET button 1 second or RESET on the optional remote timer control if installed; if the boiler fails to start, it is necessary to eliminate the fault.

Faults marked with the letter “F” cause temporary shutdowns that are automatically reset as soon as the value returns within the boiler’s normal working range.
