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.
2. Turn the master switch to ON: the display comes on and shows the function set via the boiler selector (2, 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. If you wish to activate the Aqua Premium system, proceed as follows to regulate the hot water temperature.
Turn the regulator (3, fig. 1) anticlockwise as far as it will go. The 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 is
displayed (at least 40°C).
While the DHW temperature is being regulated, the display shows the temperature setting and the tap 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 tap 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 an Authorised Service Centre
