Rapid operating instructions
The following instructions will help you to switch the boiler on quickly and regulate it for immediate use.
It is presumed that the boiler has been installed by a qualified fitter, it has been used before and is ready to operate
correctly.
If any accessories have been fitted on the boiler, these instructions will not cover them. You will therefore have to refer to
the full boiler instructions as well as to the specific instructions for the accessories.
This manual contains full details of how the boiler works, and full operating and safety instructions.
1. Open the gas cock upstream the boiler.
2. Turn the master switch to ON: the display comes on and shows the function set via the boiler selector (2 in fig. 1).
3. If you do not wish to activate the heating function, turn the boiler selector (2, fig. 1) to SUMMER. This will activate domestic hot water
(DHW) only, and the display will show the flow water temperature.
4. If you wish to activate the heating function, turn the boiler selector (2, fig. 1) to WINTER. This will activate both DHW and heating, and the
display will show the flow water temperature.
5. Decide whether you wish to activate the Aqua Premium system and proceed as follows to regulate the hot water temperature.
Turn regulator (3, fig. 1) anticlockwise as far as it will go. The water storage symbol
is displayed, showing that the Aqua Premium system
is active (if it was already active, this operation deactivates it). Then turn the selector (3) until the desired hot water temperature value is
displayed (at least 40°C).
While the DHW temperature is being regulated, the display shows the temperature setting and the DHW symbol flashes.
6. To regulate the CH water temperature, first set the regulator (4, fig. 1) to 3 o’clock (about 70°C), then regulate it as required. While the DHW
temperature is being regulated, the LCD displays the temperature setting and the CH symbol flashes.
7. Set the desired temperature on the (optional) room thermostat in the building.
The boiler is now ready to operate.
If the boiler shuts down, turn the boiler selector (2 in fig. 1) to reset for a few seconds, then back to the desired position. If the boiler does not
restart, contact a Service Centre.
