4 - SWITCHING ON AND OPERATION

4.1 Switching on the appliance
The fi rst time you turn the boiler on and in case of maintenance
work, before using the appliance you must fi ll the siphon with water
and make sure that the condensation is evacuated correctly. Fill
the condensation collection siphon pouring 1 litre of water into the
boiler combustion-analysis outlet with the boiler off , and check that:
- the safety cut-off device is fl oating
- water is fl owing correctly from the discharge pipe out of the boiler
- the condensate outlet connection line is watertight.
If the condensate outlet circuit (siphon and pipes) is working correctly, the
condensation level will not exceed the maximum.
Filling the siphon before using the appliance, and the use of a safety cut-off
device inside the siphon, prevent exhaust gases from being released into
the environment.
Repeat during standard and non-standard maintenance work.
Every time the appliance is powered up, a series of data is shown on the
display including the fl ue gas sensor meter reading (-C- XX) (see paragraph
4.3 - fault A09); the automatic purge cycle then starts, lasting around 2 min-
utes. During this phase, the three LEDs light up alternately and the symbol
is shown on the monitor (fi g. 25).
To interrupt the automatic purge cycle proceed as follows:
access the electronic board by removing the housing, turning the instru-
ment panel towards you and opening the board casing (fi g. 16).
Then:
- using a small screwdriver included, press the CO button (fi g. 26).
Live electrical parts.
To start up the boiler it is necessary to carry out the following operations:
- power the boiler
- open the gas tap to allow the fl ow 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 (fi g. 27) within the marked area,
the boiler provides domestic hot water and heating. If there is a heat re-
quest, the boiler switches on and the boiler status indicator LED lights up
with a fi xed green light. The digital monitor indicates the heating water tem-
perature, the icon to indicate heating and the fl ame icon (fi g. 29).
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fi xed green light.
The digital display shows the hot water system temperature, the icon to
indicate the hot water supply and the fl ame icon (fi g. 30).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fi g. 27) within the marked area.
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
- standard systems 40-80°C
- fl oor systems 20-45°C.
For further details, consult the "Boiler confi guration" section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery temperature
is automatically chosen by the system which rapidly adjusts ambient tem-
perature to the changes in external temperature.
To increase or decrease the temperature with respect to the value automa-
tically calculated by the electronic board, turn the heating water selector
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.
MAX
Summer mode: turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function.
If there is a domestic hot water request, the boiler switches on and the
boiler status indicator LED lights up with a fi xed green light. The digital di-
splay shows the hot water system temperature, the icon to indicate the hot
water supply and the fl ame icon (fi g. 30).
Pre-heating (faster hot water): turning the domestic hot water tempera-
ture adjustment knob to the
function. Bring the domestic hot water temperature adjustment knob back
to the required position.
This function keeps the water in the domestic hot water exchanger hot, to
reduce standby times when a request is made.
When the pre-heating function is enabled, the yellow LED next to the
symbol is lit. The monitor indicates the delivery temperature of the heating
water or the domestic hot water, according to the current request. During
burner ignition following a pre-heating request, the monitor indicates the
symbol.
To deactivate the pre-heating function, rotate the domestic hot water tem-
perature adjustment knob back to the
switch off . Bring the domestic hot water temperature adjustment knob back
to the required position.
This function cannot be activated when the boiler is OFF: function selector
to (OFF) (fi g.32).
Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (bathrooms, shower, kitchen,
etc.), turn the knob with the
the temperature and anticlockwise to reduce it. On the control panel, the
green LED fl ashes with ON for 0.5 seconds, OFF for 3.5 seconds.
The boiler is standby status until, after a heat request, the burner switch-
es on and the indicator LED turns fi xed green to indicate fl ame 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
section on "Light signals and faults").
The digital monitor indicates the fault code detected.
Automatic Temperature Control System function (S.A.R.A.) fi g. 35
Setting the heating water temperature selector to the area indicated (tem-
perature range 55 to 65°C), activates the automatic temperature control
system (frequency 0.1 sec. on; then 0.1 sec. off ; for 0.5 seconds): according
to the temperature 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 fl ashes ON for 0.5 seconds, OFF for
3.5 seconds.
Reset function
To restore operation, set the function selector to
seconds then set the function selector to the required position, checking
that the red indicator light is OFF.
At this point the boiler will automatically start and the red lamp switches on
in green.
NOTE: If the attempt to reset the appliance does not activate operation,
contact the Technical Assistance Service.
4.2 Switching off
Temporary switch-off
In case of absence for short periods of time, set the mode selector to
(OFF) (fi g. 32).
In this way (leaving the electricity and fuel supplies enabled), the boiler is
protected by the following systems:
Anti-frost device: when the temperature of the water in the boiler falls
below 5°C, the circulator and, if necessary, the burner are activated at mini-
mum output levels to bring the water temperature back to the values for
safety (35°C). During the anti-frost cycle, the symbol
on the digital monitor.
Circulator anti-blocking function: an operation cycle is activated every
24 hours.
Switching off for long periods
In case of absence for long periods of time, set the mode selector to
(OFF) (fi g. 32). Turn the main system switch OFF. Close the fuel and water
taps of the heating and domestic hot water system. In this case, anti-frost
device is deactivated: drain the systems, in case of risk of frost.
