18 - ADJUSTMENTS
The boiler has already been factory adjusted by the manufacturer. If a new
adjustment is required, for example, after extraordinary maintenance, repla-
cing the gas valve or converting from natural gas to LPG, proceed as follows.
Maximum and minimum power, minimum and maximum heating,
must be adjusted in the indicated sequence by qualifi ed staff.
- Unscrew the lower cover fi xing screw (C, Fig. 1.4)
- Pull the cover towards you and remove (A-B) (Fig. 1.5)
- Loosen the two fi xing screws (D) and remove the shell (Fig. 1.2)
- Lift up the panel and turn it forwards
- Loosen the pressure tap screw downline from the gas valve by about two
turns and connect the pressure gauge to it
CALIBRATION & SERVICE operations must be performed with the boiler
in the OFF position. To do this, press the
"- -" (Fig. E).
During parameter modifi cation operations, the "select functions" button
acts as an ENTER (confi rm) button, the
button. If no confi rmation is given within 10 seconds, the value is discar-
ded and returns to the previously set one.

Setting the password
Press and hold down the operating mode button and the
for about 10 seconds. The display will look like Fig. F.
Enter the password for accessing the parameter modifi cations function by
turning the domestic hot water temperature selector to the required value.
The password is located on the back side of the control panel. Confi rm by
pressing ENTER.
Calibration phases
Turn the domestic hot water selector to sequentially scroll the CALIBRATION
& SERVICE phases:
1
gas type (don't modify this parameter)
2
boiler power (minor parameter)
3
insulation level of building (only if external sensor is connected)
10 domestic hot water mode (Exclusive Green HE CSI: do not modify this
parameter)
45 inclination of thermoregulation curve (OTC), only if external sensor is
connected)
47 inclination of thermoregulation curve 2CH (OTC), only if external sensor
is connected)
HP maximum fan speed (do not modify this parameter)
LP minimum fan speed (do not modify this parameter)
SP ignition speed (do not modify this parameter)
HH boiler at maximum power
LL boiler at minimum power
MM fan ignition speed (do not modify this parameter)
23 maximum heating adjustment possibility (do not modify this parameter)
24 minimum heating adjustment possibility (do not modify this parameter).
The parameters 10 - HP - SP - LP - MM - 23 - 24 must be modifi ed,
by professionally qualifi ed personnel, only if absolutely necessary.
The manufacturer refuses any responsibility in the case of incorrect
setting of the parameters.
MAXIMUM VENTILATOR SPEED (P. HP)
- Select parameter HP
Qn
- Press the ENTER button, then modify the value of the parameter by turning
50-30 °C
the sanitary water temperature selector. The maximum speed of the fan is
linked with the type of gas and the power of the boiler, table 1
- Turn the sanitary water temperature selector in order to adjust the set value
- Confi rm the new value you have set by pressing ENTER.
The value indicated on the display is expressed in revs min/100 (example
3600 = 36).
The value set during this operation automatically modifi es the maximum
value of parameter 23.
