Table3 - List of anomalies
Important notice: The maintenance anomaly (the "service" message
appears on the display) indicates that the unit has exceeded 2100
operating hours. The unit must be serviced; only then hour meter can be
restarted (Technical menu) and the warning cleared. This anomaly does
not influence the normal operation of the boiler, it is merely a warning.
Important notice: when the alarm “A16” is triggered, you can check
the pressure reading on the unit. To do so, press the “Mode” button for 10
seconds to access the standard menus. You have a 2-minute window to
access the “info usuario” (user info) menu and check the pressure reading
at the unit.
Important notice:
you can only reset error messages that are flashing
on the display. If the error message is steady on the display, press the
"Mode" button once.
Important notice: the anomalies do not cause the unit to shut down.
WARNING!
In case of an emergency, switch the unit off using the standard shutdown
procedure.
