3.13 SOLAR PANELS COUPLING
FUNCTION.
In the event of integration of DHW heating with
solar panel systems, the boiler is set by default
for management of the storage tank unit via
parameter “t2” set on “2 or 3”.
3.14 ''CHIMNEY SWEEP'' FUNCTION.
When activated, this function forces the boiler
to variable output for 15 minutes.
In this state all adjustments are excluded and
only the safety thermostat and the limit ther-
mostat remain active. To activate the chimney
sweep function, press the “Reset” button (2)
until activation of the function in the absence
of DHW requests.
Its activation on the boiler display is confirmed
by the indicators flashing at the same time (11
and 12 Fig. 2-1), while on the CAR
V2
(optional)
it is indicated as “ERR>07”.
This function allows the technician to check the
combustion parameters.
Once the function is activated, it is possible to
select whether to make the check in CH status
or DHW status (when the boiler is connected to
an external storage tank unit) by opening any hot
water cock and regulating the power by turning
the "CH regulation" selector (6).
The central heating or DHW operating mode is
displayed by the relative symbols
or .
After the checks, deactivate the function switch-
ing the boiler off and then on again.
Attention: the boiler needs a certain amount of
time to stabilise itself before carrying out a com-
bustion parameters check. It is thus necessary to
wait for the boiler to carry out a self-diagnosis
test, which is signalled by the ( ) flashing
symbol. Once the symbol stops flashing, it is
possible to check the combustion parameters.
3.15 PUMP ANTI-BLOCK FUNCTION.
The boiler has a function that starts the pump at
least once every 24 hours for the duration of 30
seconds in order to reduce the risk of the pump
becoming blocked due to prolonged inactivity.
3.16 THREE-WAY ANTI-BLOCK
FUNCTION.
Both in “domestic hot water” and in “domestic
hot water-central heating” phase the boiler is
equipped with a function that starts the three-
way motorised group 24 hours after it was last
in operation, running it for a full cycle so as to
reduce the risk of the three-way group becoming
blocked due to prolonged inactivity.
3.17 RADIATORS ANTI-FREEZE
FUNCTION.
If the system return water is below 4°C, the boiler
starts up until reaching 42°C.
3.18 P.C.B. PERIODIC SELF-CHECK.
During functioning in central heating mode or
with boiler in standby, the function activates
every 18 hours after the last boiler check/power
supply. In case of functioning in domestic hot wa-

ter mode the self-check starts within 10 minutes
after the end of the withdrawing in progress, for
duration of approx. 10 seconds.
N.B.: during self-check, the boiler remains off.
3.19 AUTOMATIC VENT FUNCTION.
In the case of new central heating systems and
in particular mode for floor systems, it is very
important that dearation is performed correctly.
The function consists of the cyclic activation of
the pump (100 s ON, 20 s OFF) and the 3-way
valve (120 s D.H.W., 120 s C.H.).
The function is activated in two different ways:
- at each new boiler power supply, based on the
setting of parameter “A7”;
- by pressing the buttons at the same time (3
and 5 Fig. 2-1) for 5 seconds with the boiler in
stand-by.
IMPORTANT NOTE: if the boiler is con-
nected to the CAR
V2
the “stand-by” function
can only be activated via the remote control
panel.
In the first case, the function has duration of 8
minutes and it can be interrupted by pressing
the “reset” button (2). In the second case it has
duration of 18 hours and it can be interrupted by
simply switching the boiler on.
Activation of the function is signalled by the
countdown shown on the indicator (14).

automatic vent
Sets the activation mode of the automatic vent at each new electric powering
phase of the boiler.
This function lasts 8 minutes, and is displayed via a countdown signalled by the
special indicator (Ref. 14 Fig. 2-1). During this period the DHW and CH func-
tions are not active. The “automatic vent” function can be annulled by pressing
the “reset” button.
1: the automatic vent is enabled at each new electric power supply.
0: the automatic vent is enabled only at the first electric power supply after
having set the parameter to “0”; once the function has ended, or is inter-
rupted by pressing the “reset” button, it will not be enabled again unless
the parameter is set to “1”.
