Sets the activation mode of the automatic vent at each new electric powering

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
functions are not active. The "automatic vent" function can be annulled by
Ignition phase
pressing the "reset" button.

In the event of an alteration, anomaly "E72" appears and fast calibration is required.
3.13 SOLAR PANELS COUPLING
FUNCTION.
The boiler is set-up to receive pre-heated water
from a system of solar panels up to a maximum
temperature of 65°C. In all cases, it is always
necessary to install a mixing vale on the hy-
draulic circuit upstream from the boiler on the
cold water inlet.
Note: in order for the boiler to work properly, the
temperature selected on the solar valve must be
5°C greater than the temperature selected on the
boiler control panel.
In this condition, parameter t2 (DHW ther-
mostat) must be set at "1" and parameter t3
(solar delay time) must be set for a period that
is sufficient to receive water from a storage tank
located upstream of the boiler. The greater the
distance from the storage tank, the longer the
stand-by time to be set. Once these adjustments
have been made, when the temperature of the
boiler inlet water is the same or greater than that
set by the DHW selector switch, the boiler does
not switch on.
Description
after having set the parameter to "0"; once the function has ended, or
is interrupted by pressing the "reset" button, it will not be enabled again
unless the parameter is set to "1".
Description

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
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 chick in CH status
or DHW status 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
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 (
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
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
V2 (optional)
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 ANTIFREEZE
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
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.
