In case of operating problems or trouble, the display flashes and the fault identification code appears
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore operation it is sufficient to press
the reset button (detail 6 - fig. 1) for 1 second or use the RESET on the remote timer control (optional) if installed; if the
boiler does not restart, it is necessary to, firstly, eliminate the fault.
Other faults cause temporary shutdowns (marked with the letter F”) which are automatically reset as soon as the value
returns within the boiler's normal working range.
