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.
Maximum and minimum power, minimum and maximum heating,
must be adjusted in the indicated sequence by qualified staff.
- Unscrew 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
CALIBRATION & SERVICE operations must be performed with the boiler
in the OFF position. To do this, press the
"- -" (Fig. E).
During parameter modification operations, the "select functions" button
acts as an ENTER (confirm) button, the
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
2 boiler power (do not modify this parameter)
10 domestic hot water mode (do not modify this parameter)
3 insulation level of building (only if external sensor is connected)
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
24 minimum heating adjustment possibility.
The parameters 2 - 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.
