MAIOR EOLO
Room-sealed wall-hung combi boilers
Immergas, believing that the future
depends from the constant innovation
of the products and the use of the
most advanced technology, presents
MAIOR EOLO, the wall-hung combi
boiler designed to offer on the market
performing and at the same time easyto-use products.
The innovative technology of MAIOR
EOLO achieved the three star marking
(***), in terms of sanitary performances.
In fact, thanks to the Aqua Celeris
system, an innovation designed and
patented by Immergas, the hot sanitary
water is immediately available at the
withdrawal, thus drastically reducing
the typical waiting time of traditional
instantaneous boilers.
Another feature is the great space
flexibility: all boilers are room-sealed,
granting the maximum adaptability even
to the most reduced spaces.
Available in three models with heat
outputs from 24 kW to 32 kW, MAIOR
EOLO always offers the most adequate
answer to each single market exigency.
COMFORT UNDER CONTROL
MAIOR EOLO makes it all extremely
easy and intuitive. The control board,
equipped with backlit display and
descriptive icon buttons, allows for an
immediate function managing, ensuring
a simple and immediate daily use of
the boiler. Moreover, two knobs only
result very useful when it comes to
regulate the heating and hot sanitary
water temperatures. An innovative auto
diagnosis system, with relative code
visualization on the display, further
facilitates the technician’s work.
MAIOR EOLO advanced electronics
consents combining with the climatic
thermoregulation optional kits; the
remote controls (CARV2 and CAR
Universal); the integration to thermal
solar systems to heat, if necessary,
the solar storage tank water. Placing
two temperature probes guarantees an
optimal heating and hot sanitary water
temperature control.
ESSENTIAL DESIGN
The sober design and the reduced
dimensions allow to easily locate MAIOR
EOLO in any room of your home. A small
door covers knobs and buttons only,
leaving the backlit liquid crystal display
always visible.

NEW ADVANCED ELECTRONICS
The innovative electronics equipping MAIOR EOLO
allows for the combination with the new Immergas
remote control system range and the external probe
as well, increasing the thermal system energetic
efficiency and at the same time diminishing gas
consumption. The electronic board has also an
innovative solar function, in case of hot water
production by means of a thermal solar system.
.02
AQUA CELERIS.
INNOVATION MADE IN IMMERGAS
Thanks to an Immergas patented system, it is
possible to reach the desired water temperature
at the moment of the withdrawal and considerably
reduce the waiting time and electrical consumptions.
Aqua Celeris is a micro storage (2 litres) inserted
in the primary circuit equipped with a modulating
electric resistance. The advantages are:
Reduced waiting time in case of hot sanitary water withdrawals
Reduced water consumption as the desired temperature is rapidly reached
Maintaining of the performances in time. Aqua Celeris is connected to the primary circuit,
consequently preventing any calcareous deposit on the mini storage surface
Reduction of electrical consumptions thanks to the coibentation against thermal dispersions
Can be switched off using the proper button on
the control board

NEW THERMOREGULATION
MAXIMUM INSTALLATION FLEXIBILITY
MAIOR EOLO is combinable with the new CARV2 (*) and
CAR Universal, both modulating room thermostats to remotely
control the boiler.
The MAIOR EOLO range was designed to facilitate at
the most the substitution of previous boilers, leaving
the measure and disposition of wall connections
unchanged. Moreover, thanks to the 20 cm only of
space between the hydraulic connections and the
wall, the installation work is extremely eased.
Common functions:
• Weekly setting on 2 room temperature levels
(comfort - reduced)
• Easy and intuitive controls
• Possible errors visualization
• 9 fixed climatic curves regulation (if connected
to the external probe)
• Anti-freeze function
CARV2 (*) specific functions:
• New aesthetic
• Holiday function
• Building thermal inertia setting
• Climatic curve auto adapting function
• Anti-freeze function from 0 to 10 °C
(*) Availability 2nd semester 2010.
IDEAL FOR THE OUTDOORS
MAIOR EOLO boilers, besides the IPX5D protection
index, feature technical solutions to protect at the
best the internal components and operate with
absolute reliability even in partially protected spaces
(e.g. under a balcony). In this case, is also available a
cover kit to outlet the combustion air directly outside
the house.
The standard protection guarantees the boiler
performance up to -5 °C, up to -15 °C with an antifreeze protection kit (option).

(*) The boiler is equipped with a 90° gas cock with ¾”
connections and Ø 18 mm to be welded fitting.
N.B.: The gas cock must come out 200 mm at least from
the connections horizontal wall.
During the life of a boiler, performance is influenced by external factors, e.g. water hardness,
atmospheric agents, system limiting, etc. The published data refers to new products correctly
installed and used, in accordance with local regulations. N.B. We recommend regular periodic
maintenance of the appliance.
