Notes:
1.
Parameters with more than one description vary their function and/or range in rela-
tion to the setting of the parameter given in brackets.
2.
Parameters with more than one description are reset to the default value if the pa-
rameter given in brackets is modified.
3.
The Maximum Heating Power parameter can also be modified in Test Mode.
4.
If left at 0 the parameter Minimum fan rpm (for Low NOx versions only) does not en-
able the possibility to modify the preset rpm values for minimum and for fan start; if
set above 0, this possibility is enabled, therefore the values that will be set for the
parameter itself (P22) and for the next one (P23) will be used; while the settable
range of parameter P23 is limited (80-180), lower values between 1 and 79 can also
be set in P22: in such cases the software will always work with the real minimum
rpm, i.e. 800 rpm (which corresponds to the value 80 in the parameter).

In case of damaged sensor, the card displays hyphens.
Press the Reset button to return to the Service Menu. Press the Reset button for 20 sec-
onds to exit the card Service Menu or exiting occurs automatically after 15 minutes.
"Hi" - History Menu
The card can store the last 11 faults: the History datum item H1: represents the most re-
cent fault that occurred; the History datum item H10: represents the least recent fault that
occurred.
The codes of the faults saved are also displayed in the corresponding menu of the Re-
mote Timer Control.
Press the Heating buttons to scroll the list of faults in increasing or decreasing order.
Press the DHW buttons to display the value.
Press the Reset button to return to the Service Menu. Press the Reset button for 20 sec-
onds to exit the card Service Menu, or exiting occurs automatically after 15 minutes.
"rE" - History Reset
Press the Eco/Comfort button for 3 seconds to delete all the faults stored in the History
Menu: the card will automatically exit the Service Menu, in order to confirm the operation.
Press the Reset button for 20 seconds to exit the card Service Menu, or exiting occurs

4.2 Commissioning
Before lighting the boiler
•
Check the seal of the gas system.
•
Check correct prefilling of the expansion tank.
•
Fill the water system and make sure all air contained in the boiler and the system
has been vented.
•
Make sure there are no water leaks in the system, DHW circuits, connections or boil-
er.
•
Check correct connection of the electrical system and efficiency of the earthing sys-
tem.
•
Make sure the gas pressure for heating is that required.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
B
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED THERE MAY BE
RISK OF SUFFOCATION OR POISONING DUE TO GAS OR FUMES ES-
CAPING; DANGER OF FIRE OR EXPLOSION. ALSO, THERE MAY BE A
RISK OF ELECTRIC SHOCK OR FLOODING THE ROOM.
Checks during operation
•
Switch the unit on.
•
Check the tightness of the fuel circuit and water systems.
•
Check the efficiency of the flue and air/fume ducts while the boiler is working.
•
Make sure the water is circulating properly between the boiler and the systems.
•
Make sure the gas valve modulates correctly in the heating and domestic hot water
production stages.
•
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 in cap. 5.
•
Make sure that with no demand for heating, the burner lights correctly on opening a
hot water tap. Check that in heating mode, on opening a hot water tap, the heating
circulating pump stops and there is regular production of hot water.
•
Make sure the parameters are programmed correctly and carry out any required
customisation (compensation curve, power, temperatures, etc.).
