- Mixed zone.
The central heating temperature
in the mixed zone is adjusted using parameter
“P93” in the “M9” menu using the selector
switch (3), the relative temperature is shown
on the display (24) using the indicator (7) and
the “P93” indication appears (Fig. 2-5). 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 “CH ON”
is displayed (24) on the status indicator (6) and
at the same time as burner ignition the flame
presence indicator switches on (8) with relative
power scale and the indicator (9 and 7) with
the instantaneous outlet temperature 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.
Functioning in Winter mode

Functioning in Winter mode
with direct zone room C.H.
The flow temperature in the mixed zone can be
displayed during the central heating request.
Enter the "M9" menu and select parameter
"P91" on the display (24) using the indicator
(7), the instant temperature detected on boiler
outlet appears.

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 (
) is displayed.
From now on selectors (1 and 3) and buttons
(A and B) are inhibited and controls are placed
with CAR
V2
.
Note:
In the central heating mode, the CAR
V2
makes a boiler ignition request for the main set
zone (whether it be direct or mixed). Regard-
ing the central heating temperature value, only
check the direct zone. To adjust the temperature
in the mixed zone it is therefore necessary to
act on the control panel as described at the
“Winter” point.
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 now on, it is
possible to make adjustments from either the
Super CAR or the boiler, except for the direct
zone room central heating temperature, which
is shown on the display but managed by the
Super CAR.
Note:
In the central heating mode, the Super
CAR makes a boiler ignition request for the
main set zone (whether it be direct or mixed).
Regarding the central heating temperature
value, only check the direct zone . To adjust
the temperature in the mixed zone it is there-
fore necessary to act on the control panel as
described at the “Winter” point.
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.
•
Domestic hot water priority function.
By
pressing button “B” the D.H.W. priority func-
tion is activated, which is marked by the symbol
(15) switching off on the display (24).
Attention:
the disabled function keeps the wa-
ter contained in the storage tank at a tempera-
ture of 20°C for 1 hour, giving the functioning
priority to room central heating.
•
Functioning with external probe (Fig. 2-8)
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
temperature measured (Par. 1.5 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. 1-6 and
1-7 Offset value).
- Direct zone correction.
The 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
correction. The “SET” indication is displayed
(Fig. 2-8). By turning the selector switch (3)
in a clockwise direction the temperature
increases and in an anti-clockwise direction
it decreases.

- Mixed zone correction
. The correction can
be activated by parameter "P93" in the "M9"
menu using the selector switch (3) and is kept
active for any external temperature measured,
the modification of the offset temperature is
displayed using the indicator (7). 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 “CH ON”
is displayed (24) on the status indicator (6) and
at the same time as burner ignition the flame
presence indicator switches on (8) with relative
power scale and the indicator (9 and 7) with
the instantaneous outlet temperature 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.
Winter operation mode with external probe
(optional)
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.
