Maximum/Minimum Ventilator Speed; Ventilator Igintion Speed; Maximum/Minimum Power Adjustment; Maximum/Minimum Electric Heating Adjustment - Beretta EXCLUSIVE GREEN 25 CSI Installation And User Manual

MAXIMUM VENTILATOR SPEED (P. HP)
- Select parameter HP
- Press the ENTER button, then modify the value of the
parameter by turning the sanitary water temperature
selector. The maximum speed of the ventilator is linked
with the type of gas and the power of the boiler
- Turn the sanitary water temperature selector in order to
adjust the set value
- Confirm 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 modifies
the maximum value of parameter 23.
MINIMUM VENTILATOR SPEED (P. LP)
- Select parameter LP
- Press the ENTER button, then modify the value of the
parameter by turning the sanitary water temperature
selector. The minimum speed of the ventilator is linked
with the type of gas and the power of the boiler
- Turn the sanitary water temperature selector in order to
adjust the set value
- Confirm 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 modifies
the maximum value of parameter 24.

proceed to adjust the next parameter (LL - adjusting the
minimum), if different modify the value by turning the
maximum power adjustment screw with a screwdriver
(clockwise to decrease) until you obtain a value contained
in table 1.
MINIMUM POWER ADJUSTMENT - LL
- Select the parameter LL (with the boiler still OFF) and
wait for the boiler to come on.
- Check that the minimum CO
(see paragraph "Checking combustion parameters", page
31) corresponds with the values indicated in table 2.

table, proceed to adjust the parameter by turning the
maximum power adjustment screw after having
unscrewed the protective cap (clockwise to increase) until
you obtain a value contained in table 2.
IGNITION SPEED (P.MM)
- Select parameter MM.
The boiler starts at the slow ignition speed.
- Turn the heating water selector to increase or decrease
the ventilator speed.
