1. Put the boiler in heating or DHW mode for at least 2 minutes.
2. Activate TEST mode (see *** 'TEST mode activation' on page 272 ***).
3. Using a combustion analyzer, connected to the arrangements located on the starting accesso-
ries on top of the boiler, check that the CO
maximum and minimum power, matches that given 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 Hi, ME and Lo values to obtain values of
CO as per table 9.

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
