Ignition procedure

When the boiler is powered, the following information appears on the display:
• all symbols alight (1 second);
• software version (1 second);
• The message "InI" appears (for a few seconds);
• All turns off (1 second);
• The message "Fx.x" appears on the display. (2 seconds);
• The message "Px.x" appears on the display. (2 seconds);
• The boiler and heating system venting function starts. The text "(t17)" appears on the display and this phase takes 5 minutes
(this function is enabled only during initial ignition);
• "OFF" appears (the knobs are fully rotated in the clockwise direction at the factory).
At the end of the venting phase, the boiler is ready for operation.
• Turn the knob of the central heating circuit to set the required temperature of the system.
• Turn the knob of the DHW circuit to set the required temperature of the DHW.

Shut-down

To turn off the boiler, disconnect the electric power supply at the two-pole switch installed upstream of the boiler, and close the
gas tap.
In these conditions, the boiler is not protected against frost.

Frost protection

It is good practice to not drain the entire heating system as filling up with water again could cause unnecessary and harmful
scale to build up inside the boiler and the heating elements. If the boiler is not used during the winter and is therefore exposed
to the danger of frost, add some specific anti-freeze to the water in the system (e.g.: propylene glycol with corrosion and scale
inhibitors). The electronic boiler management system includes a "frost protection" function for the heating system which, when
flow temperature falls below 7 °C, operates the pump. If the temperature reaches 4 °C, the burner runs until the flow temperature
reaches 10 °C. The burner then turns off and the pump continues to run for 15 minutes.
The function is operative if: the boiler is electrically powered, there is gas, system pressure is normal and the boiler is not
blocked.

Reading out measured values

Press the button to view information on operation of the boiler.
• press the button for 1 second to view the work mode (for example: "t.17" = Venting function being completed).
• press the button again for 1 second to view the operating sub-status or the relative work function (for example: "u.00" = Boiler
in stand-by).
• press the button again for 1 second to view the operating temperature for heating: the symbol
value in °C then appears.
• press the button again for 1 second to view the operating temperature for DHW: the
temperature value in °C appears.
• press the button again for 1 second to view the power level between 0 and 100: the
