RANGE RATEd
This boiler can be adapted to the thermal requirements of the
system; it is possible, in fact, to set the maximum boiler delivery for
operation in heat mode. Refer to the "Adjustments" chapter for the
calibration settings.
Once the required output has been set (maximum heating - pa-
rameter 23), indicate the value on the self-adhesive label supplied.
For subsequent checks and adjustments, always refer to the set
value.

In the event of short absences, press the
You will see two segments in the middle of the display (Fig.11).
In this way (leaving the electricity and fuel supplies enabled), the boiler
is protected by:
- the anti-freeze system (Fig.12): when the temperature of the water in
the boiler falls below the safety values, the circulator and burner are
activated at minimum output levels to bring the water temperature back
within the safety limits (35°C).
The symbol will light up on the display.
- circulator anti-blocking system: an operation cycle is activated every 24
hours.

charging the system

If the system charge pressure value reaches 0.6 bar, the pressure
value will flash on the display (Fig.14).
If the value falls below a minimum safety level (0.3 bar), fault code 41
will appear on the display (Fig.15) for a limited time then, if the fault
remains, fault code 40 will be shown (refer to the "Faults" chapter).
With fault 40 (Fig.16), reset the correct pressure value in the
following way:
- press the key
- turn on the filling tap (outside the boiler) and wait until the pressure
indicated on the display is between 1.5 bar and 2.0 bar.
If the system needs to be charged several times, you are advised
to contact the Technical Assistance Service to check the heating
system seal (ensuring there are no leakages).
