hot water function is activated. The display alternatively indicates
the temperature of the domestic hot water and the preheating sta-
tus (P0 not activated, P1 activated) (fig.5)
WINTER ( ): with the selector in this position, the heating water
and domestic hot water functions are activated. The display alter-
natively indicates the delivery temperature of the heating water or
the domestic hot water depending on current demand (fig. 5) and
the pre-heating status (P0 not activated, P1 activated).

ON-OFF PRE-HEATING FUNCTION (

ting function is activated which keeps the water in the domestic hot
water exchanger hot in order to reduce waiting times.
The pre-heating function can be activated or disactivated (P0 not
activated � P1 activated) by turning the selector to this position.
The function works both in winter and summer. Turn the function
selector to the required position (summer, winter or OFF) after

with the selector in this position the traditional domestic hot water
function provided by the water tank is activated. The display indi-
cates the delivery temperature.
WINTER ( ): with the selector in this position, the boiler produ-
ces hot water for heating and, if connected to an external water
tank, it provides water to it to allow it to prepare domestic hot water.
The display indicates the delivery temperature of the heating water
(fig. 5).

Adjusting heating water temperature

To ad�ust the heating water temperature turn the knob marked
(fig. 6) clockwise to increase and anticlockwise to decrease.
When turning the knob, the required temperature automatically ap-
pears on the digital display.
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 "�oiler configuration" section.
Adjusting heating water temperature with an external probe
connected
When an external probe is connected, the value of the delivery tem-
perature is automatically chosen by the system which rapidly ad�usts
ambient temperature to the changes in external temperature.
To increase or decrease the temperature with respect to the value
automatically calculated by the electronic board, turn the heating
water selector (fig. 6) clockwise to increase and anticlockwise to
decrease.
Ad�ustment settings range from comfort levels � 5 to + 5 which are
