To start up the boiler it is necessary to carry out the following oper-
ations:
- power the boiler
- turn on the gas tap to allow fuel flow
- adjust the ambient thermostat to the required temperature (~20°C).
Turn the mode selector to the required position:
Winter
Turn the function selector to within the adjustment range. The boil-
er produces domestic hot water and heating water. The boiler lights
automatically in response to a heat request. The digital display indi-
cates the heating water temperature. The boiler lights automatically
in response to a request for domestic hot water. The display indicates
the domestic hot water temperature.
WINTER MODE
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the mode selector to
within the adjustment range (turn clockwise to increase the value and
anticlockwise to reduce the value).
Depending on the type of system, the most suitable temperature
range can be pre-selected:
- standard systems 40-80 °C
- floor installations 20-45°C.
For details see paragraph “Boiler configuration”.

DELIVERY
TEMPERATURE
Adjusting the heating water temperature with an external probe
connected
When an external probe is installed, the delivery temperature is auto-
matically selected by the system, which quickly adjusts the ambient
temperature according to variations in the outside temperature. If you
want to alter the temperature value (increasing or reducing the val-
ue automatically calculated by the electronic card), use the heating
water temperature selector: turn it clockwise to increase the temper-
ature, or anticlockwise to reduce it.
The correction possibility is between 15° C and 25° C levels of com-
fort (0 = 20° C), shown on the digital display by rotating the knob.
Summer
The standard domestic hot water-only mode is activated by turning
the selector to the summer symbol
. The boiler lights automatically
in response to a request for domestic hot water. The digital display
indicates the delivery temperature.
SUMMER MODE
Adjustment of the domestic hot water temperature
To adjust the domestic hot water temperature (for baths, showers,
kitchen etc.), turn the dial with the
symbol clockwise to increase
the value, or anticlockwise to decrease the value (mi. value 37°C -
max. value 60 °C). The boiler is in standby until the burner switches
on following a heat request. The boiler continues to function until
the temperatures set on the boiler are reached, or the heat request
terminates; it will then go back to standby. In the case of a temporary
stop the digital display shows the fault code.
ADJUSTING THE DOMESTIC HOT WATER TEMPERATURE
Heating Temperature Control function (C.T.R.)
Turn the heating water temperature selector into sector highlight-
ed with white markers to activate the C.T.R. self-adjusting system:
depending on the temperature set on the ambient thermostat and
the time taken to reach it, the boiler automatically varies the heating
water temperature by reducing operating time, thereby achieving in-
creased comfort and energy savings.
