4 - SWITCHING ON AND OPERATION
4.1 Switching on the appliance
When the boiler is first started the siphon for collecting the condensate
is empty. It is therefore indispensable to create a head of water filling
the siphon before starting up, following these instructions:
- remove the siphon by releasing it from the plastic pipe connec-
ting to the combustion chamber
- fill the siphon about 3/4" full with water, making sure it is free of
any impurities
- check the float of the plastic cylinder
- put back the siphon, being careful not to empty it, and secure it
with the clip
The plastic cylinder inside the siphon has the job of preventing combustible
gas coming out into the surroundings if the appliance is started without first
creating the head of water in the siphon.
Repeat this operation during routine and extraordinary maintenance opera-
tions.
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 min-
utes. During this phase, the three LEDs light up alternately and the symbol
is shown on the monitor (fig. 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 (fig. 16).
Then:
- using a small screwdriver included, press the CO button (fig. 26).
Live electrical parts (230 V AC).
To start up the boiler it is necessary to carry out the following operations:
- power the boiler

- turn the mode selector to the desired position:
Winter mode: by turning the mode selector (fig. 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 fixed green light. The digital monitor indicates the heating water tem-
perature, 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 marked area.
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 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.
Summer mode: turning the selector to the summer mode symbol
28) activates the traditional domestic hot water only function.
