USER GUIDE
1a GENERAL WARNINGS AND SAFETY
The instruction manual is an integral part of the product and it must there-
fore be kept carefully and must accompany the appliance; if the manual
is lost or damaged, another copy must be requested from the Technical
Assistance Service.
Boiler installation and any other assistance and maintenance opera-
tions must be carried out by qualified personnel according to the
provisions of local legislation.
For installation, it is advisable to contact specialised personnel.
The boiler must only be used for the application foreseen by the
manufacturer. The manufacturer shall not be liable for any damage
to persons, animals or property due to errors in installation, calibra-
tion, maintenance or due to improper use.
The safety and automatic adjustment devices must not be modified,
during the system life cycle, by the manufacturer or supplier.
This appliance produces hot water, therefore it must be connected
to a heating system and/or a domestic hot water mains, compatible
with its performance and output.
In case of water leakage, close the water supply and contact the
Technical Assistance Service immediately.
In case of absence for long periods time, close the gas supply and
switch off the electrical supply main switch. If there is a risk of frost,
drain the boiler.
From time to time check that the operating pressure of the hydraulic
system does not go below 1 bar.
In case of failure and/or malfunctioning, deactivate the appliance,
and do not try to repair or operate directly on it.
Appliance maintenance must be carried out at least once a year:
scheduling it with the Technical Assistance Service will avoid wasting
time and money.
Boiler use requires strict observation of some basic safety rules:
Do not use the appliance in any manner other than its intended
purpose.
It is dangerous to touch the appliance with wet or damp body parts
and/or when barefoot.
Under no circumstances cover the intake grids, dissipation grids and
ventilation vents in the installation room with cloths, paper or any
other material.
Do not use electrical switches, telephone or any other object that
causes sparks if there is a smell of gas. Ventilate the room by open-
ing doors and windows and close the central gas tap.
Do not place anything in the boiler.
Do not perform any cleaning operation if the appliance is not discon-
nected from the mains power supply.
Do not cover or reduce ventilation opening of the room where the
generator is installed.
Do not leave containers and inflammable products in the installation
room.
Do not attempt to repair the appliance in case of failure and/or mal-
functioning.
It is dangerous to pull or twist the electric cables.
Children or unskilled persons must not use the appliance.
Do not carry out operations on sealed elements.
For better use, remember that:
- periodic external cleaning with soapy water not only improves its appear-
ance but also preserves panelling from corrosion, extending its life cycle;
- if the wall-mounted boiler is enclosed in a hanging unit, leave at least 5
cm for ventilation and maintenance;
- installation of a room thermostat will greatly improve comfort, a more ra-
tional use of the heat and energy saving; the boiler can also be connected
to a programmable timer in order to control the switching on and off of the
appliance during the day or week.
2a SWITCHING ON THE APPLIANCE
Every time the appliance is powered up, a series of data is shown on
the display including the flue gas sensor meter reading (-C- XX) (see
paragraph 4.3 - fault A09); the automatic purge cycle then starts, lasting
around 2 minutes. During this phase, the three LEDs light up alternately
and the symbol is shown on the monitor (fig. 25).
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the flow of fuel
- set the room thermostat to the required temperature (~20°C)
- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 27) within the area mar-
ked + and -, the boiler provides hot water for heating and, if connected to
an external storage tank - supplies hot water for DHW.
If there is a heat request, the boiler switches on and the boiler status indi-
cator LED lights up with a fixed green light. The digital monitor indicates
the heating water temperature, the icon to indicate heating and the flame
icon (fig. 29).
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fixed green light.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the flame icon (fig. 30)
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 27) within the area marked + and -.
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
- standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the "Boiler configuration" section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery tempera-
ture is automatically chosen by the system which rapidly adjusts ambient
temperature to the changes in external temperature. To increase or decre-
ase the temperature with respect to the value automatically calculated by
the electronic board, turn the heating water selector (Fig. 12.6) clockwise
to increase and anticlockwise to decrease. Adjustment settings range from
comfort levels - 5 to + 5 which are indicated on the digital display when the
knob is turned.
Summer mode (only active when the external storage tank is con-
nected): turning the selector to the summer mode symbol
activates the traditional domestic hot water only function, the boiler sup-
plies water at the temperature set on the external storage tank.
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fixed green light. The digital
display shows the hot water system temperature, the icon to indicate the
hot water supply and the flame icon (fig. 30).
Adjustment of the domestic hot water temperature
CASE A heating only with storage tank - adjustment does not apply
CASE B heating only + external storage tank with thermostat - adjustment
does not apply.
CASE C heating only + external storage tank with probe - to adjust the
temperature of the domestic hot water in the storage tank, turn the knob-
but with the symbol (fig. 32) clockwise to increase water temperature
and anti-clockwise to lower it.
On the control panel, the green LED flashes with ON for 0.5 seconds, OFF
for 3.5 seconds.
The boiler is standby status until, after a heat request, the burner switches
on and the indicator LED turns fixed green to indicate flame presence.
The boiler continues to operate until the temperatures set on the boiler are
reached, or the heat request is met; after which it goes back on standby.
If the red LED indicator near the
lights up, this means the boiler is in temporary shutdown status (see the
chapter on Light signals and faults).
The digital monitor indicates the fault code detected.
Automatic Temperature Control System function (S.A.R.A.) fig. 34
Setting the heating water temperature selector to the area marked
"AUTO", activates the automatic temperature control system (frequency
0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): according to the tempera-
ture set on the room thermostat and the time taken to reach it, the boiler
varies automatically the heating water temperature reducing the operating
time, allowing greater ease of operation and energy saving. On the control
panel, the green LED flashes ON for 0.5 seconds, OFF for 3.5 seconds.
