1. Put the boiler in heating or DHW mode for at least 2 minutes.
2. Activate TEST mode (see "TEST mode activation" on page 77 ).
3. Using a combustion analyzer connected to the devices located on the starting accessories
above the boiler, check that the CO
and minimum power, matches that indicated in table 9.

4. If the combustion values do not match, do the manual calibration as described in the following
paragraph.
5. Activate a manual calibration and then modify the values of Hi, ME and Lo to obtain the CO
values as per table 9.
Calibration

Manual calibration
Calibration procedure.
• Put the boiler in standby mode.
• To activate manual calibration, simultaneously press the OFF/Summer/Winter buttons (detail
7 - fig. 1) and the "Heating +" button (detail 4 - fig. 1) for 5 seconds. Calibration will start in
heating request. If there is insufficient heat dissipation, a DHW request can be made (the three-
way valve will automatically switch in the DHW circuit).
• Manual calibration will start. During the ignition phase, the flashing symbols MA and "nu"+ ra-
diator + faucet alternating will appear. With flame present (flashing icons "Hi + flame + faucet
+ radiator") the boiler will do the check first in Hi (maximum power) then ME (Medium power)
then Lo (minimum power). Calibration can be stopped at any time by pressing the "OFF/Sum-
mer/Winter" and "Heating +" buttons for 5 seconds.
• Afterwards, a numerical value between 0 and 6 will appear on the display (at this point the
boiler is at minimum power "Lo"). At this point the CO

ME, Lo), increasing the value will increase the CO
Press the "Heating +" button, the display will show the icon "ME", a numerical value will appear
when the ignition/intermediate power is reached. Using the "DHW + and -" buttons, adjust the
CO at medium/ignition power ME; each time the "DHW + or -" buttons are pressed, the dis-

level). Press the "Heating +" button, the icon "Hi" will appear on the display and a numerical
value will appear when the maximum power is reached.
Using the "DHW + and -" buttons adjust the CO
Each time the "DHW + or -" buttons are pressed, the display will show the modified value and
