Wall-mounted boiler with fan-assisted sealed
combustion chamber for central heating and
instantaneous domestic hot water production,
equipped with AQUA CELERIS system

MAIOR EOLO 4 E is a wall-mounted, sealed chamber,
fan-assisted generator (type C) for central heating and the
production of domestic hot water.
The boiler can be installed according to configuration B
22
using
the relevant kit (optional).
The boilers in the MAIOR EOLO 4 E range are approved for
installation outside buildings in a partially protected location.
N.B.:
A partially protected location is a place where the appliance
is not exposed to the direct effects of the weather (rain, snow, hail,
etc...).
The appliance is available with effective outputs of 24 kW
(20.640 kcal/h), 28 kW (24.080 kcal/h) and 32 kW (27.520
kcal/h).
Adjustment and control are entrusted to an integrated P.C.B.
with micro processor with continuous flame modulation by
means of 2 sensors (domestic water and central heating).
The new electronics allow the new Comando Amico Remoto
remote control (CAR
V2
) to be connected so that the boiler
can be managed and controlled remotely with extreme ease;
it is also designed for systems that are subdivided into zones
and to be connected to the new Multi-system Distribution
Manifolds (DIM
V2
).
The boiler has a standard anti-freeze safety devicethat protects
it to a minimum temperature of -5°C (optional to -15°C).
The hydraulic circuit has a bronze water-gas heat exchanger
and uses a new multi-purpose hydraulic unit made from
composite material (ICHS)
which houses the pump and
3-way electric valve that allow the boiler water to circulate in
the CH system or in a STAINLESS steel plate heat exchanger
General features
for the instantaneous production of DHW according to
necessity, as well as the hydraulic circuit control devices
(absolute system pressure switch, adjustable system by-pass, 3-bar
calibrated system safety valve, etc.).
A domestic water flow switch allows the boiler to be activated
when domestic hot water is requested.
The range features the "Aqua Celeris" system, which
drastically reduces wait times for domestic hot water supply.
The boiler is deisgned to receive pre-heated water from a solar
storage tank; by activating this function through the boiler
parameters, the burner and the boiler turn on only if necessary
in order to reach the set domestic hot water set point.
The intake of combustion air inside the sealed chamber and
flue extraction are ensured by a fan which is guaranteed to
operate correctly by means of a differential flue pressure switch.
The parameters to operate the boiler can be set by rotating
the knobs where you can view the operating status, mode and
anomalies that have occured using a digital interface with an
easy-to-read backlit display screen, located in the centre of
the dashboard.
The appliance has an IPX5D electric insulation rating: this
means that the boiler is protected against jets of water and
high humidity levels.
