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).
