COMMISSIONING
In this case, when the CONTACT is CLOSED, the heat re-
quest is made by the flow sensor on the basis of the
outdoor temperature, to obtain a nominal temperature
in the room at DAY level (20°C).
THE OPENING OF THE CONTACT does not produce a switch-
off, but a reduction (parallel translation) of the climatic
curve on NIGHT level (16°C).

In this case too, the user can indirectly modify the
HEATING setpoint value by inserting an offset on the
reference DAY temperature (20°C) or NIGHT temperature
(16°C). This offset may vary from [-5 to +5].
To correct the offset, refer to paragraph "3.7 Adjusting
the heating water temperature with an outdoor temper-
ature sensor connected".

Initial start-up

ƒ When the power is switched on, the backlight is il-
luminated, all the icons and segments light up for 1
second, and the firmware version is visualised for 3
seconds:
The interface then shows the status active in that mo-
ment.
Venting cycle
9
Every time the boiler is powered, the automatic
venting cycle (lasting 6 min) is run. When the vent-
ing cycle is in progress, all heat requests are inhib-
ited (apart from DHW requests when the boiler is
not OFF) and the sliding message -AIR appears on
the interface screen.
The venting cycle can be interrupted by pressing and
holding button 2 (the RESET icon lights up on the dis-
play). The cycle can also be interrupted by a DHW re-
quest, if the boiler is not OFF.
ƒ Adjust the room thermostat to the required tempera-
ture (~ 20°C) or, if the system is equipped with a timed
thermostat or timer, make sure it is "active" and ad-
justed (~ 20°C).
ƒ Now set the boiler on WINTER or SUMMER, depending
on the type of operation required.

ƒ The boiler will start up and then continue working
until the set temperatures are reached, after which it
will go back to standby.

Operating status

To change the operating status from WINTER to SUMMER
and then to OFF, press button 1 until the relative icon
appears on the display.
WINTER MODE

until both the DHW icon and the heating icon appear
on the display.
-20
The interface normally displays the delivery temperature
unless there is a DHW request in progress, in which case
the DHW temperature is displayed.
ƒ When there is a heat request and the boiler is ignit-
ing, the icon appears on the display.
Heating REQUEST: the radiator icon flashes
SUMMER MODE (only with a storage tank connected)
ƒ Bring the boiler to SUMMER mode by pressing button 1
until the DHW icon appears on the display.
ƒ In this status, the boiler activates the traditional
"DHW-only" function and the interface usually shows
the delivery temperature. In the case of DHW supply,
the display will show the DHW temperature.
DHW REQUEST: the tap icon flashes
OFF
