can be summarized in the following key points:
- noi seless functioning, thanks to maximum insulation of the device by means of
innovative special materials that ensures minimum heat loss.
- high degree of reliability, thanks to a careful choice of materials and to server tests
carried out during production for each unit built.
- high per formance with maximum efficiency, thanks to a modulation of electric
power to the heating elements, according to the actual need of energy by the
system or the need of sanitary water. The system D.E.S. manages the device with
temperature probes positioned in each sensitive point of the boiler, so as to
manage both comfort and economy functioning, in order to reduce power
consumption when the device is not used at the maximum capacity or demand.
- the appliance is fully adjustable both in water temperature of the heating system
(with the possibility to choice of system at high and low temperature forthe
underfloor systems) and in the domestic hot water temperature.
- The assembly of the components has been realized in order to allow an easy
access to them, all from the front of the unit, for ordinary and extraordinary
maintenance.
We recommend you to follow our instructions, and we suggest to contact the area
authorized ser vice FIAMMA in order to prepare a planned maintenance contract
which can ensure suitable operation at maximum efficiency and safety, so that your
machine use can go a long way. In renewing our thanks, our technical department
and our sales network, are at your disposal for any further information.

POSITIONING OF THE BOILER
The appliance must always be installed on a vertical solid wall capable of supporting its
weight, using the support bracket included in the packaging.
The bracket must be secured to the wall by means of three M8 screws with appropriate
plugs for the type of wall (not supplied with the boiler).
The appliance must be attached to the top of the bracket, inserting the bent section of the
same through the boiler frame at the back.

mode, winter or summer.
Heating system water pressure reading
The analogue hydrometer on the control panel has a bar dial from 0 to 6 bar. The current
central heating system water pressure is indicated by the black needle. The optimum
central heating system water pressure is between 1 and 1.5 bar. The pressure can exceed
1.5 bar, to a maximum of 2 bar (maximum expansion of the system during a temperature
rise). Pressures over 2 bar are not within the operating range of the appliance. When this
level is exceeded, the action of the pressure transducer will cause the display of the
" ERROR F 10 " error message and the boiler will remain in operation. However, if the
threshold of 2.8 bar is exceeded, the system stops until the pressure falls back within the
allowed range. The minimum operating pressure is 0.8 bar (+/-0.2 bar). If the pressure
detected by the transducer is less than 0.7 bar, the " ERROR F 1 " message appears
and the operation of the system stops. The last safety feature of the boiler is the
mechanical valve, which when a pressure of 3 bar is reached starts to release water
through the VSR drain, the position of which can be found in the hydraulic connection
diagram (see page 5).

SWITCHING ON THE BOILER
The boiler is switched on by pressing the luminous main switch found on the left of the
display in the dashboard. If the boiler is connected to a single-phase power supply source,
the button lights up when pressed (230-240 V - 50 Hz). After the short graphic
presentation, set the day and time (if required) and choose summer/winter operating mode
using the ■ (SW5) key at the bottom right (pressing again will switch off the boiler, while
keeping it powered).
MAIN SCREEN
The status bar at the top shows the operating status of the boiler or, in case of fault, the
fault code.
The table below shows all the possible status bar messages:

The value below the radiator icon is the temperature detected by the central heating
system delivery probe, while below the tap icon is the temperature detected by the
sanitary hot water system probe. The and icons flash in case of central heating
system or sanitary hot water request..
If management with external SE probe is enabled (parameter menu ” idx: 001 val:
001 ”), it is also possible to set the room temperature setpoint.
The screen will show the symbol instead of the symbol, and the room temperature
setpoint instead of the central heating system delivery temperature. At the centre is a
graduated bar that shows the operating power of the boiler. In case of heating request,
the icon appears at the side of the bar.
The rectangles on the left of the screen show the status of the triacs powering the central
heating system heating elements (full rectangle for active triacs and empty rectangle for
triacs that are not powered). The lines next to the rectangles show the power output on
each triac: 1 power line 1/2 kW, 2 power lines 3/4 kW and 3 power lines 6 kW.

If "OFF" mode is selected, the display shows the following:
If the boiler is connected to a WiFi network, the following icons appear: . The
graduated bar indicates the quality of the WiFi signal (3 bars very good, 2 bars medium, 1
bar poor). In the event of WiFi network or internet communication fault, these icons may
start flashing or disappear. A detailed indication of the type of WiFi fault can be found
under the "Info" item in the "WiFi Menu" discussed in the appropriate paragraph.

Setting boiler
The second item " Setting boiler ” of the " SETTINGS MENU " can be used to
view and modify the boiler and central heating system setting parameters. The parameters
and their meanings are described in detail in the relevant paragraph.
The menus for setting the boiler and heating system parameters have been sorted into
sub-menus according to the type of setting and access right.
The " Installer menu " only contains the essential parameters for the configuration
of the boiler type.
When accessed, this menu shows the " Read parameter " screen:
where the parameter index is shown on the left and
its current value on the right. The value does not
appear instantaneously but is transferred each time
from the control board of the boiler. Before its
appearance, three dashes will be displayed for a few
moments "---“. Press ▼ (SW6) [↓] and ▲ (SW7) [↑] to scroll through the entire list of
parameters. Press ■ (SW5) [SET] to access the parameter edit screen. Finally, press ◄
(SW3 ) [ESC] to return to the " PARAMETERS MENU ".
In the " Write parameter " screen, the index is blocked and the value is highlighted.
Press ▼ (SW6) [-] and ▲ (SW7) [+] to change
the parameter value, followed by ■ (SW5) [OK] to
save the new value. Press ◄ (SW3) [ESC] to
return to the " Read parameter " screen without
changing the parameter.

18
Access to the other sections of the " PARAMETERS MENU " (" Factory menu ",
" Device menu ") is password protected, meaning that the correct password must be
entered in the password screen.
Accessing " Faults history " allows to view the list of the faults occurred in the
boiler. If there are no faults, the following screen is displayed
In case of fault or lockout, the above screen is updated as follows:
Where:
ID: Index ID of the fault occurred.
Fault F: fault or lockout code.
Faults are indexed in succession starting with " ID:
001 ". Each time there is a new fault the previous
ones are moved upwards, up to a maximum of 10. After that, every time there is a new
fault the oldest one is deleted.
Press ▲ (SW7) [+] and ▼ (SW6) [-] to scroll through the faults occurred.

19
The " Degasser " option allows to activate the boiler circulator, to remove air residues
from the system. Also in this case, ▼ (SW6) [-], ▲ (SW7) [+] and ■ (SW5) [OK] can
be used to activate or deactivate the function.
During this function, the PWM circulator maximum and minimum speed operating statuses
are alternated, in order to facilitate the escape of air bubbles from the hydraulic circuit. The
sequence is illustrated below.
When this function is active, a timer appears on the display to indicate the time required to
complete the function.
Under " Boiler version ", it is possible to view the version of the software loaded on
the boiler control board.
The last item, " Special functions ", is password protected and is used to activate
the boiler demo mode. During demo mode, fictitious
information is shown on the display so that, for
example, it is possible to simulate running with triacs
activated, without them actually being powered.
