• Winter ( ):
in this mode the boiler functions
both for heating domestic hot water and heating
the environment. The temperature of the domestic
hot water is always adjusted using the selector
switch (1), the central heating temperature is
adjusted using the selector switch (3) and the
relative temperature is shown on the display (24)
using the indicator (4) and the “SET” indication is
shown (Fig. 2-4). By turning the selector switch (3)
in a clockwise direction the temperature increases
and in an anti-clockwise direction it decreases.
During the request for room heating the word-
ing “CH ON” is displayed (24) on the status
indicator (6) and at the same time as burner
ignition the flame on indicator switches on (8)
with relative power scale and the indicator (9
and 7) with the instantaneous outlet tempera-
ture from the primary heat exchanger. In the
central heating phase, if the temperature of the
water contained in the system is sufficient to
heat the radiators, the boiler can only function
with the activation of the boiler pump.

Operation with Comando Amico Remoto
remote control
V2
(CAR
V2
) (Optional).
In
the event of connection to the CAR
V2
remote
control, the boiler automatically detects the
device and the symbol (
) appears on the
display. From this moment onwards all controls
and adjustments are referred to the CAR
V2
. The
stand-by button “
”, the Reset button "C", the
menu access button "D" and the DHW priority
button "B" however remain active on the boiler.
Attention:
If the boiler is put into stand-by
(10) the "CON" connection error symbol will
appear on the CAR
V2
remote control. The
CAR
V2
remote control is however constantly
powered thus stored programs are not lost.
•
Operation with Super Comando Amico
Remoto remote control (Super CAR) (Op-
tional).
In the event of connection to the Super
CAR remote control, the boiler automatically
detects the device and the (
) symbol
appears on the display. From this moment it
is possible to make adjustments indifferently
from the Super CAR remote control or the
boiler. Except for the central heating tempera-
ture that is shown on the display but managed
by the Super CAR remote control.
Attention:
If the boiler is put into stand-by (10)
the “ERR>CM” connection error symbol will
be displayed on the Super CAR. The Super CAR
remote control is however constantly powered
thus stored programs are not lost.
•
“COMFORT” or “SAVING” DHW function.
Pressing button “B”on the display makes the
(
) symbol appear and the “COMFORT”
function is activated, which allows you to have
the maximum amount of water available set
according to user requirements by adjusting
the selector switch (1). The production of the
hot water is guaranteed by the solar system and
the boiler.
Pressing button “B” again passes to “SAV-
ING” mode, signalled by the indicator (15)
off. In this way priority is given to the solar
system to produce DHW, thus guaranteeing a
minimum temperature of the water contained
in the storage tank of 45°C. In this mode it is
also possible to regulate the temperature of the
water contained in the cylinder by acting on the
selector switch (1).
•
Functioning with external probe (Fig. 2-6)
optional.
In the case of a system with optional
external probe, the boiler flow temperature
for room central heating is managed by the
external probe depending on the external tem-
perature measured (Par. 1.8 and par. 3.8 under
item “P66”). It is possible to modify the flow
temperature from -15°C to +15°C with respect
to the adjustment curve (Fig. 1-7 Offset value).
This correction, which can be activated using
selector switch (3) is kept active for any external
temperature measured. The modification of the
offset temperature is displayed via the indicator
(7). The indicator (4) shows the current flow
temperature and after a few seconds from the
modification it is updated with the new correc-
tion. The “SET” indication is displayed (Fig.
2-6). By turning the selector switch (3) in a
clockwise direction the temperature increases
and in an anti-clockwise direction it decreases.
During the request for room heating the word-
ing “CH ON” is displayed (24) on the status
indicator (6) and at the same time as burner
ignition the flame on indicator switches on (8)
with relative power scale and the indicator (9
and 7) with the instantaneous outlet tempera-
ture from the primary heat exchanger. In the
central heating phase, if the temperature of the
water contained in the system is sufficient to
heat the radiators, the boiler can only function
with the activation of the boiler pump.
From this moment the boiler functions automati-
cally. With no demand for heat (central heating
or domestic hot water production) the boiler
goes to “standby” function, equivalent to the
boiler being powered without presence of flame.
N.B.:
it is possible that the boiler may start-up
automatically if the antifreeze function is acti-
vated (13). Moreover, the boiler can function
for a brief period of time after a withdrawal of
domestic hot water in order to take the domestic
hot water temperature back into temperature.
Attention:
with the boiler in stand-by mode (
), hot water cannot be produced and the fol-
lowing safety functions are not ensured: pump
anti-block device, antifreeze and three-way
anti-block device.
