10.02 Ignition
Check than any shut-off valves in the heating system and domestic hot water circuit outside of the boiler are open.
Open the gas cock upstream from boiler and press the main switch. The boiler will perform an self-test cycle lasting
approximately one minute, at the end of which it is ready for operation. The ignition and shut-down of the burner
assembly are completely automatic operations, which depend on the requirements of the heating system or
domestic hot water circuit.
10.03 Shut-down
In the event of extended periods of inactivity close the gas cock upstream from the boiler and disconnect the
electrical power supply to the appliance. In this case, the boiler antifreeze protection function is also disabled; this
function switches on the burner assembly when the heating system temperature falls below 5°C. For extended
periods of inactivity during the winter months, in order to avoid damage due to freezing, all the water should be
drained from the boiler, both the domestic hot water and the heating system; alternatively, drain only the domestic
hot water and introduce the special antifreeze into the heating system.
10.04 Accessing the operating menu
Pressing the M - mode button once accesses the operating menu. Pressing the M mode button again dislays the

10.05 Setting the heating system temperature
Set, using the room thermostat or remote control, the desired temperature inside the rooms. When acting on the
room thermostat, the boiler is turned on and the heating system water is brought to the central heating outlet set
temperature or calculated temperature (with temperature scrolling active). On reaching the required temperature
inside the rooms, the generator will switch off.
If no room thermostat or remote control is installed, the boiler will maintain the heating system temperature at the
central heating outlet setpoint.
To set the central heating outlet temperature, access the operating menu, and using the button
1 – central heating outlet temperature. On pressing one of the buttons

the button
. To cancel the setting, do not press the button
10.06 Setting the domestic hot water temperature
Set, using the control boiler panel, the required domestic hot water outlet temperature. On opening a hot water tap,
the system regulates itself to supply water at the set temperature, according to the flow rate of delivery and the
temperature of the cold water supplied to the boiler. If in terms of delivery or temperature difference between the
inlet and outlet, the thermal capacity of the generator is exceeded (refer to the technical data), the outlet
temperature will be proportionally lower than the setpoint.
