SWITCHING OFF
Switching off for short periods
For brief absences press the button to switch off the boiler. The
display will show two segments in the central area (Fig. 3). When the
boiler remains powered with the gas tap open, it is protected by the
following systems:
- anti-freeze (Fig. 12a) : when the temperature of the water in the boiler
falls below safety values, the circulator and the burner work at minimum
power to increase the water temperature to a safe value (35°C). The
symbol lights up on the display.
- circulator anti-block: one operating cycle is performed every 24
hours.
Switching off for long periods
For prolonged absences press the button to switch off the boiler
(Fig. 3). The display will show two segments in the central area. Turn
the main switch to “off”.
Turn off the gas tap under the boiler by turning it clockwise (Fig. 12b).

In this case, the anti-freeze and anti-block systems are disabled.
Empty the water circuit or suitably protect it with a good make of
anti-freeze.
Boiler functions
Semi-automatic filling
The boiler features a semi-automatic filling device which turns on by
pressing the button when the corresponding symbol is shown on
the display (Fig. 13).
If this condition occurs it means that the system is incorrectly pressurised
though the boiler will continue to work regularly. Press the circuit filling
button to start-up the filling sequence.
Press the circuit filling button a second time to interrupt the filling
sequence. During filling, the drops of the circuit filling symbol and the
growing pressure value appear on the display in a cascade sequence.
After filling, the symbol is displayed for a few moments and then
turns off.

Adjusting domestic hot water temperature
To adjust domestic hot water temperature, turn switch D (Fig. 9) clockwise
to increase and anticlockwise to decrease. The bar segments light up
(every 3°C) as the temperature is increased.
The selected temperature value appears on the display.
When choosing the temperature, both for heating and domestic hot water,
the display shows the value being selected. About 4 seconds after the
selection has been made, the modification is memorised and the display
returns to the delivery temperature read by the probe.
Working the boiler
Adjust the room thermostat to the required temperature (approx. 20°C).
If there is a demand for heating water, the boiler starts and the symbol
is shown on the display (Fig. 10). The boiler will remain working until the
set temperatures are reached, after which it will go on stand-by. In the
event of ignition or operating faults, the boiler will perform a “safety stop”.
The flame symbol will go out and the fault code and will be displa-
yed (Fig. 11). For a description of faults and how to reset them, consult
chapter “Troubleshooting”.
