18 - ADJUSTMENTS
The boiler has already been factory adjusted by the manufacturer.
If a new adjustment is required, for example, after extraordinary
maintenance, replacing the gas valve or converting from natural gas to
LPG, proceed as follows.
b
Maximum and minimum power, minimum and maximum
heating, must be adjusted in the indicated sequence by
qualified staff.
- U nscrew the lower cover fixing screw (
C
, Fig. 1.4)
- Pull the cover towards you and remove ( A-B ) (Fig. 1.5)
- Loosen the two fixing 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
b
CALIBRATION & SERVICE operations must be performed with
the boiler in the OFF position. To do this, press the button until
the display shows “- -” (Fig. E).
b
During parameter modification operations, the “select functions”
button acts as an ENTER (confirm) button, the button acts as an
ESCAPE button. If no confirmation is given within 10 seconds, the
value is discarded and returns to the previously set one.
Setting the password
Press and hold down the operating mode button and the button together
for about 10 seconds. The display will look like Fig. F.
Enter the password for accessing the parameter modifications 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. Confirm
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 ( C.S.I. : 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).
b
The parameters 10 - HP - SP - LP - MM - 23 - 24 must be modified,
by professionally qualified 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
- Press the ENTER button, then modify the value of the parameter by
turning the sanitary water temperature selector. The maximum speed
of the fan is linked with the type of gas and the power of the boiler,
