List Of Faults - Ferroli SKY ECO F Serie Instrucción De Uso, Instalación Y Mantenimiento

3.4 FAULTS
The heater is equipped with an advanced self-diagnostic system. If a problem arises with
the unit, the fault symbol will flash on the screen and the respective code will be displayed.
Some faults, identified with the letter "A," will block unit operation.
To restore operation, simply press the RESET key (4 - fig. 1) for 1 second. If the heater
does not reset, the fault must be resolved.
Faults identified by the letter "F" cause temporary blocks that are automatically resolved
when the value returns to the heater's normal operating range.
