• The card goes to the setting “q01”; displaying the currently saved value by pressing the DHW buttons.
• If the minimum pressure read on the pressure gauge is different from the nominal one, proceed in increments/de-
crements of 1 or 2 units of the parameter “q01” by pressing the DHW buttons: after each change, the value is stored;
wait 10 seconds for the pressure to stabilise.
• Recheck both settings by pressing the heating buttons and if necessary correct them by repeating the procedure
described above.
• Pressing the Eco/Comfort button for 2 seconds returns to TEST mode.
• Deactivate TEST mode (see next par.).
• Disconnect the pressure gauge.
TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 1) for 5 seconds to activate TEST mode. The boiler lights at the maxi-
mum heating power set as described in the next paragraph.
The heating and DHW symbols (fig. 13) flash on the display; the heating power will appear alongside.
fig. 13- TEST mode (heating power = 100%)
Press the heating buttons (details 3 and 4 - fig. 1) to increase or decrease the power (Minimum=0%, Maximum=100%).
By pressing the DHW “-” button (detail 1 - fig. 1), boiler output is immediately adjusted to minimum (0%). By pressing
the DHW “+” button (detail 2 - fig. 1), boiler output is immediately adjusted to maximum (100%).
If the TEST mode is activated and enough hot water is drawn to activate the DHW mode, the boiler remains in TEST
mode but the 3-way valve goes to DHW.
To deactivate the TEST mode, press the heating buttons (details 3 and 4 - fig. 1) at the same time for 5 seconds.
The TEST mode is automatically disabled in any case after 15 minutes or by not drawing hot water (if enough hot water
has been drawn to activate the DHW mode).
