Beretta Exclusive (range) DATA SHEET

Exclusive

Standard Efficiency Wall-Hung Boilers

Residential Heating

Exclusive

EXCLUSIVE represents Beretta top of the

range wall-hung boiler.

Its wide offer includes both room-sealed

models, with outputs of 26, 30 and 35kW
(combi and only heating versions), and
conventional flue models, with outputs
of 24 and 28kW (combi and only heating
versions).

Efficiency ★★★, the highest according

to European Directive EEC 92/42, on
room-sealed models (C.S.I. and R.S.I.).

Exclusive MIX system: continuous

electronic air/gas modulation, ensuring
high efficiency in any operation mode (on
room-sealed models: C.S.I. and R.S.I.).

“Survivor” function in DHW mode,

allowing the boiler, in the event of failure
of the DHW NTC probe, to continue to
operate.

Reduced waiting time for DHW supply

thanks to pre-heating function (on
combi models).

Clever and intuitive control panel with

backlit display.

S.A.R.A. and S.A.R.A. Booster systems:

automatic temperature control in heating
mode (see dedicated section).

Built-in climatic thermoregulation that can

be activated through the external probe
(as option) for a high comfort level inside
the house.

3-speed circulator with 5 metres head (6

metres head on the 35 kW model).
Electrical protection IPX5D.
Hydraulic connections, gas and DHW taps

supplied as standard.
EXCLUSIVE can be converted to LPG

through specific LPG kit (as option).
The lower connections cover, supplied

as standard, allows to hide hydraulic

connections, ensuring a tidy installation.

The simplicity of comfort

EXCLUSIVE is characterized by an
essential and stylish design.
The control panel is located under
a modern flap from which appears
a wide LCD display that shows all
information about the boiler status.
By simply rotating two knobs, it is
possible to set CH and DHW
temperatures. By simply pushing a
button, you can choose your comfort
level and activate the Easy Filling
system, when the boiler requires it.
The control panel also integrates the
thermoregulation function (external
probe as option).

Winter Summer

Central heating ON and domestic hot water
activated.
In this mode S.A.R.A. system (Automatic
Temperature Control) can be enabled by
positioning the water temperature between
55°C and 65°C.
This setting is recommended in spring and
autumn, or in areas or periods in which
winter is not hard.

Winter
comfort

Faster heating and domestic hot water.
In this mode S.A.R.A. Booster system
(Automatic Temperature Control) is enabled.
The domestic hot water Pre-heating
function is activated, thus allowing a quicker
DHW delivery.
This setting is recommended in cold areas,
or during the hard winter periods.

Central heating OFF and domestic hot water
activated.

Summer
comfort

Central heating OFF and optimum
stabilization of DHW temperature.
The burner is continuously kept on at the
minimum power during the small DHW
demands, avoiding in this way that the
burner switches off every time when the
domestic water from the net is slightly
warm. This feature allows an optimum
temperature stabilization of DHW.

Winter

Central heating ON (domestic hot water
available only if an external tank is
connected).
In this mode S.A.R.A. Booster system
(Automatic Temperature Control) is
activated.

Summer

Central heating OFF (domestic hot water
available only if an external tank is
connected).

Easy Filling

On combi models is activated the innovative Easy Filling system:

New

The first boiler with a new semi-automatic
filling system.

Safe

Thanks to a double control of the pressure,
the filling is automatically stopped if it
detects any leak in the system, so as not to
worsen the loss.

On only heating models, filling is done through an external tap.

Smart

It alerts you when you need to fill the
system before the pressure drops below the
lockout level.

Easy

Filling the system has never been so simple:
one push of the button is enough.

S.A.R.A. and S.A.R.A. Booster systems

S.A.R.A. and S.A.R.A. Booster systems
(Automatic Temperature Control), patented
by Beretta, are designed to provide a high
comfort level in the central heating mode,
allowing you to reach the desired room
temperature more rapidly.
When there is a demand for heating,
the appliance will automatically raise the
heating flow temperature every 20 minutes

with S.A.R.A. or every 10 minutes with
S.A.R.A. Booster, by 5 °C steps (see

diagram).

When the heating request has been
satisfied, the boiler automatically restores
the flow temperature to the setted value,
thus allowing a better temperature stability
of the radiators.
EXCLUSIVE integrates on all combi models
both systems, providing maximum comfort
in every climate condition.
S.A.R.A. Booster is automatically activated
by selecting WINTER COMFORT on the
control panel. This setting is recommended

in cold areas, or during the hard winter
periods.
S.A.R.A. is activated by selecting WINTER
on the control panel and by setting the
temperature of the central heating circuit
between 55°C and 65°C. This setting is
recommended in spring and autumn, or in
areas or periods when winter is not hard.
On the only heating models, S.A.R.A.
Booster is always activated in WINTER
mode.

The MIX system

All the room-sealed models of EXCLUSIVE
range are equipped with the “MIX system”,
that maintains the air/gas ratio always
optimal, by controlling the fan speed.
In this way EXCLUSIVE ensures high
efficiency performance in each mode of
operation, with a consequent reduction in
the consumption of gas and electricity.
Moreover, thanks to the “MIX system”,
EXCLUSIVE boilers fit flues of different
lengths for a maximum flexibility of
installation.

Climatic Thermoregulation: more comfort and saving

The built-in climatic Thermoregulation is a
standard feature for the whole EXCLUSIVE
range. Your installer just has to connect
the external sensor (optional) to EXCLUSIVE
electronic board, to enable this function.

The Thermoregulation function adjusts the
boiler operation according to the external
climate changes in order to optimize comfort
and maximize saving.
