The boiler adjustment system is constantly monitorized by an electronic control unit signalling the possible faults by
intermittant or continuos luminous warning signals to the leds situated on the front panel (fig.5) which are:
● Shutdown warning led (1)
● ON/OFF led (2)
● Fault warning led (3)

Should the boiler shut down it must be reset by rotating function selector to the reset position A.
