"Hi" - History Menu
The microprocessor can memorise the total hours with card fed (Ht), the last 10 faults
(with detail of the time they occurred, referring to parameter Ht) and hours of burner op-
eration (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 temperature 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 --> The time when the fault occurred (referring to Ht)
H2 Fault code --> The time when the fault occurred (referring to Ht)
H3 Fault code --> The time when the fault occurred (referring to Ht)
H4 Fault code --> The time when the fault occurred (referring to Ht)
H5 Fault code --> The time when the fault occurred (referring to Ht)
H6 Fault code --> The time when the fault occurred (referring to Ht)
H7 Fault code --> The time when the fault occurred (referring to Ht)
H8 Fault code --> The time when the fault occurred (referring to Ht)
H9 Fault code --> The time when the fault occurred (referring to Ht)

4.2 Start-up
B
Checks to be made at first lighting, and after all maintenance operations that
involved disconnecting from the systems or an intervention on safety devices
or parts of the boiler:
Before lighting the boiler
• Open any on-off valves between the boiler and the systems.
• Check the seal of the fuel system.
• Check correct prefilling of the expansion tank.
• Fill the water system and make sure that all air contained in the boiler and the sys-
tem has been vented, by opening the air valve on the boiler and any air valves on
the system.
• Make sure there are no water leaks in the system, domestic hot water circuits, con-
nections or boiler.
• Check correct connection of the electrical system and efficiency of the earthing sys-
tem
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
Checks during operation
• Turn the unit on as described in sec. 2.3.
• Check the seal of the fuel circuit and water systems.
• Check the efficiency of the flue and air-fume ducts during boiler operation.
• Make sure the water is circulating properly between the boiler and systems.
• Check correct boiler lighting by performing various tests, turning it on and off with
the room thermostat or remote control.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table on sec. 5.3.
• Ensure the seal of the fumebox and burner door.
• Make sure the burner works properly. This check must be made with the special in-
struments, following the manufacturer's instructions.
• Check correct programming of the parameters and carry out any required customi-
sation (compensation curve, power, temperatures, etc.).

4.3 Maintenance
Periodical check
To ensure correct operation of the unit over time, have qualified personnel carry out a
yearly check, providing for the following:
• The control and safety devices must function correctly.
• The fume exhaust circuit must be perfectly efficient.
• Check there are no obstructions or dents in the fuel supply and return pipes.
• Clean the filter of the fuel suction line.
• Measure the correct fuel consumption
• Clean the combustion head in the fuel outlet zone, on the swirl disc.
• Leave the burner running at full rate for approximately ten minutes, then analyse
the combustion, checking:
- All the elements specified in this manual are set correctly
- Temperatures of the fumes at the flue
- CO2 percentage content
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For possible clean-
ing do not use chemical products or wire brushes.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise, bring
it to that value.
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• Check the magnesium anode and replace it if necessary.
The boiler casing, control panel and aesthetic parts can be cleaned with a soft
A
and damp cloth, if necessary soaked in soapy water. Do not use any abrasive
detergents and solvents.
Burner disassembly
To clean the burner, refer to the Manufacturer's instructions.
Boiler cleaning
1. Disconnect the power supply to the boiler.
2. Remove the burner (see preceding paragraph).
3. Undo the nuts F and open the door.
4. Clean the inside of the boiler and the entire path of exhaust fumes, using a tube
brush or compressed air.
5. Then close the door, fixing it with the two nuts.
6. Refit the burner.
