8. Notifications and errors

8.1 Service
When on the display appears "Service",
clean carefully the boiler/thermostove and
its hopper (see chap. Maintenance). It is
not an alarm and does not affect the boiler
operation. Press ESC button for 3 seconds
to reset the notification.
8.2 Standby
The "Standby" notification appears when
the temperature achieves the set point.
The boiler control panel stops conveying
pellet and the flame goes out. The boiler/
thermostove turns itself on at a new ther-
mal request.
8.3 Over temperature
Alarm "Er01" is displayed when water or
pellet security thermostat is active. The
boiler/thermostove can go in over tempe-
rature if:
• Zoned heating system doesn't have an
open zone;
• Circulation pump is blocked;
• Shut off valves are closed;
• If domestic hot water kit is installed and
the display shows false hot water re-
quest, contact Technical Support;
• The temperature in the hopper is too
high.
To turn the boiler/thermostove on:
• Solve the cause of over temperature;
The thermal security thermostats can be
found below the power cable (fig. 23).
fig. 23 - Security Thermostats
Unscrew the black caps that cover the whi-
te buttons, press the buttons until hearing
a click. At this point the thermostats are
reset;
• Proceed with the ignition.
8.4 Wet
"WET" notification displays if the tempe-
rature difference between the water lea-
ving the boiler and the system return is
too big, over the value set in the factory.
If "WET" notification appears more than 5
times during a day, the display will show
alarm Er59, condensate hazard. Please
contact your installer.
