“Hi” - History Menu
The microprocessor is able to store the total hours with card powered (Ht), the last
10 faults (with details of time they occurred relevant to parameter Ht) and burner
operation hours (Hb).
The History datum item H1 represents the most recent fault that occurred, whereas
the History datum item H10 represents the least recent. The codes of the faults
saved are also displayed in the corresponding menu of the Opentherm remote
control.
Note for calculation of hours:
• Every 24 hours, the number shown in the part of the display normally reserved
for system pressure is increased by one unit.
• Every hour, the number shown in the part of the display normally reserved for
room temperature is increased by one unit.
Press the Heating buttons to scroll the list of faults.
Ht
Total hours with card fed.
H1
Fault code --> Time fault occurred (relevant to Ht)
H2
Fault code --> Time fault occurred (relevant to Ht)
H3
Fault code --> Time fault occurred (relevant to Ht)
H4
Fault code --> Time fault occurred (relevant to Ht)
H5
Fault code --> Time fault occurred (relevant to Ht)
H6

Press the Reset button to return to the Service Menu. Press the Reset button for 10
seconds to exit to the card Service Menu.
“rE” - History Reset
Press the Eco/comfort button for 3 seconds to delete all the faults and the hours
stored in the History Menu: the card will automatically exit the Service Menu, in

4.2 Commissioning
Checks to be made at
fi
rst lighting, and after all maintenance operations
involving disconnection from the systems or an operation on safety de-
vices or partsof the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the tightness of the fuel system.
• Check the pre-
fi
lling of the expansion tank
• Fill the water system and make sure that all air contained in the boiler and the
system has been vented by opening the air vent valve on the boiler and any vent
valveson the system.
• Make sure there are no water leaks in the system, hot water circuits, connec-
tions orboiler.
• Make sure the electrical system is properly connected and the earth system
worksproperly.
• Make sure there are no
fl
ammable liquids or materials in the immediate vicinity
ofthe boiler.
• Fit the pressure gauge and the vacuum gauge on the pump (remove after start-
ing)of the burner.
• open the gate valves along the diesel pipe
Start-up
fi
g.30 - Starting
A
When the thermostatic line closes, the burner motor starts turning together with
thepump: all the oil sucked is sent to the return. The burner blower and the ignition
transformer are also working, therefore the following stages are carried out:
•
fi
rebox preventilation.
• prewash of a part of the oil circuit.
• preignition, with discharge between electrode tips.
B
At the end of prewash, the unit opens the electromagnetic valve: the oil reaches the
nozzle, where it is
fi
nely sprayed.
Its contact with the discharge between the electrode tips creates the
fl
ame.
The safety time begins simultaneously.
