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. 4.1).
• 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. 1).
• 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. 4.1).
• Disconnect the pressure gauge.

Heating power adjustment
To adjust the heating power, switch the boiler to TEST mode (see sec. 4.1). Press the
heating buttons detail 3 - fig. 1 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. 4.1).
Configuration Menu
Press the DHW buttons together for 10 seconds to access the configuration Menu. 7 pa-
rameters indicated by the letter "b" are available: 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 modify the value of a parameter: the change will be au-
tomatically saved.

Notes:
1. Parameters with more than one description vary their function and/or range in rela-
tion to the setting of the parameter given in brackets.
2. Parameters with more than one description are reset to the default value if the pa-
rameter given in brackets is modified.
To exit the configuration Menu press the DHW buttons together for 10 seconds, or exiting
occurs automatically after 2 minutes.
