TEST mode activation
Press the heating buttons (details 3 and 4 - fig. 17) together for 5 seconds to activate the
TEST mode. The boiler lights at the maximum heating power set as described in the fol-
lowing section.
The heating and DHW symbols (fig. 25) flash on the display; the heating power will ap-
pear alongside.
fig. 9 - TEST mode (heating power = 100%)
Press the heating buttons (details 3 and 4 - fig. 17) to increase or decrease the power
(Min.=0%, Max.=100%).
By pressing the DHW "-" button (detail 1 - fig. 17), boiler output is immediately adjusted
to min. (0%). By pressing the DHW "+" button (detail 2 - fig. 17), boiler output is imme-
diately adjusted to max. (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. 17) to-
gether for 5 seconds.
The TEST mode is automatically deactivated in any case after 15 minutes or on stopping
of hot water drawing (if enough hot water has been drawn to activate the DHW mode).
Pressure adjustment at the burner
Since this unit has flame modulation, there are two fixed pressure settings: minimum and
maximum, which must be those given in the technical data table according to the type of
gas.
• Connect a suitable pressure gauge to the pressure point "B" downstream of the
gas valve.
• Activate the TEST mode (see cap. 9.1).
• Press the Eco/Comfort button for 2 seconds to access the gas valve Calibration
mode.
• The card goes to the setting "q02"; displaying the actually saved value, by pressing
the DHW buttons .
• If the pressure gauge reading is different from the nominal maximum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter "q02" by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
• Press the heating button "-" (ref. 3 - fig. 17).
• The card goes to the setting "q01"; displaying the actually saved value, by pressing
the DHW buttons .
• If the pressure gauge reading is different from the nominal minimum pressure, pro-
ceed by increases/decreases of 1 or 2 units of parameter "q01" by pressing the
DHW buttons : the value is stored after each modification; wait 10 seconds for the
pressure to stabilise.
• Recheck both adjustments by pressing the heating buttons and adjust them if nec-
essary by repeating the above procedure.
• Press the Eco/Comfort button for 2 seconds to return to the TEST mode.
• Deactivate the TEST mode (see cap. 9.1).
• Disconnect the pressure gauge.

Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 9.1). Press the
heating buttons detail 3 - fig. 17 to increase or decrease the power (min. = 00 - max. =
100). Press the reset button within 5 seconds and the max. power will remain that just
set. Exit TEST mode (see sec. 9.1).
Configuration Menu
Press the DHW buttons together for 10 seconds to access the configuration Menu. 7 pa-
rameters are available, indicated by the letter "b", which are not modifiable from Remote
Timer Control.
Press the Heating buttons to scroll the list of parameters in increasing or decreasing or-
der. Press the DHW buttons to view or modify the value of a parameter: the modification
will be automatically saved.
