the display will show the fault code. There are faults that in order to restore operation it suffi ces to
press RESET (2 - fi g. 1); if the boiler fails to start, it is necessary to resolve the fault indicated by the
operating LEDs (faults from 1 to 25); other faults cause temporary shutdown that are automatically reset
