Each time the "DHW + or -" buttons are pressed, the display will show the modified value and
then the icon "Hi"(to indicate the maximum power level). After adjusting the CO
power, the three power levels "Hi", "ME" and "Lo" can be scrolled by pressing the "Heating +
or -" buttons to recheck or correct the CO
press the OFF/Summer /Winter buttons (detail 7 - fig. 1) and the "Heating +" button (detail 4
- fig. 1) for 5 seconds.
• The calibration mode will be deactivated in any case after about 5 minutes if no buttons are
pressed.
Complete manual calibration
Complete manual calibration can be performed only if parameter b27 is set to 5.
To activate this procedure it is necessary to put the boiler in standby and simultaneously press the
OFF/Summer/Winter buttons (detail 7 - fig. 1) and the "Heating +" button (detail 4 - fig. 1) for 5
seconds.
Parameter b27 can be set to value 5 manually via the service menu or automatically in the fol-
lowing cases:
• changing the parameter "gas type" b03
• setting parameter P67 to 1
• changing the value of parameter P68
• doing "Restore Factory Values"
Complete manual calibration is required in the following cases:
• after replacing the PCB
• after changing the gas (b03)
• setting parameter P67 to 1
• after changing the value of parameter P68
• after setting parameter b27 to 5 for replacement of components such as the electrode, burner,
gas valve, fan or for installations with maximum flue resistance
• in case of fault conditions A01, F96 and A06 or in other faults when required (see table 12.
Respect the sequence of fault cures).
Complete manual calibration resets the combustion parameters recorded previously and must
be done only in the cases described above.
Procedure:
• Put the boiler in standby mode and activate the complete manual calibration mode by simulta-
neously pressing the "OFF/Summer/Winter" and "Heating +" buttons for 5 seconds. The dis-
play will show the flashing symbols "Au" and "to". After burner ignition (flashing icons
"Hi+flame+faucet+radiator"), the boiler will do the calibration in the three power levels "Hi",
"ME" and "Lo". At the end, a numerical value will be displayed (At this point the boiler is at
minimum power "Lo") If the system heat dissipation is not sufficient to end the procedure a
DHW request can be activated only after the burner has ignited.
• If the CO values are not within the range table 9, proceed as follows: using the "DHW + and
2
-" buttons, adjust the CO2 at minimum power (Lo). Each time the "DHW + or -" buttons are
pressed, the display will show the modified value and then the icon "Lo" (to indicate the mini-
mum power level).
• Increasing the value will decrease the CO
• Press the "Heating +" button to go to Medium/ignition power "ME", the display shows the icon
"ME"; a numerical value will appear when the medium/ignition power is reached. Using the
"DHW + and -" buttons, adjust the CO
display will show the modified value and then the icon "ME" (to indicate the medium/ignition
power level). Press the "Heating +" button to go to maximum power "Hi". The icon "Hi" ap-
pears on the display and a numerical value will appear when the maximum power is reached.
• Using the "DHW + and -" buttons, adjust the CO
