4 DESCRIPTION OF THE APPLIANCE
4.1 Characteristics
ALU HE
aluminium boilers generate heat through condensation
and are designed to heat rooms and produce domestic hot water,
if the system contains a storage tank. They are composed of:
– an aluminium body, with low water content and high exchange
surface, to maximise energy efficiency and heat yields
– a total pre-mix microflame burner in stainless steel that
allows high modulation ratios, combustion stability and low
emissions of pollutants (Class NOx = 6), to be achieved
– a variable speed fan required for modulation and air/gas
mixing
– a combustion circuit which can be "Type C" (sealed) or
"Type B" (open) with respect to the place where the boiler is
installed, depending on the configuration of the smoke outlet
adopted during installation
– a control panel which. if equipped with an external sensor,
allows the delivery temperature to be adjusted according to
the outdoor temperature (sliding temperature operation).
The boiler therefore provides only the heat the User actually
needs, avoiding energy being wasted and the associated
costs. If there are malfunctions or faults, the specific error
codes are displayed, which simplifies the work of Technical
Service.
During planning solutions have been adopted to:
– constantly achieve the best air/gas mixture
– reduce heat dispersion
– reduce noise.
Sime ALU HE
boilers can be connected to 0-10 V DC controls, to an
auxiliary sensor and to the
Sime Home
or
Sime Home Plus
remote
controls. They can manage direct systems or direct systems and
two mixed systems (or two groups of mixed systems connected
in parallel), if the optional kits "mix 1 kit-code 8092275" and
"mix 2 kit-code 8092276" are installed. A solar system can
also be installed using the "solar kit-code 8092277". All kits
are optional accessories to be ordered separately. After each
stoppage, whether automatic or manual, post-ventilation and
post-circulation are performed. The system should include an
INAIL safety device, which is mandatory for ITALY ONLY, and a
plate heat exchanger or hydraulic separator, depending on the
system characteristics.
Sime ALU HE boilers also have the following functions:
– anti-freeze function, which is activated automatically if the
temperature of the water inside the boiler falls below the
value set under “PAR 35” and if the outdoor temperature falls
below the value set under “PAR 36”
– antiblocking function for the pump and any diverter valve,
which is activated automatically every 24 hours if there have
been no requests for heat
– the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the
parameters and combustion efficiency
– anti-legionella function when a storage tank is used
– automatic adjustment of the ignition output and maximum
heating output. The outputs are managed automatically by the
electronic circuit board to ensure maximum usage flexibility
for the systems
– disposal function
– screed drying function, to keep the floor at a pre-set
temperature profile with the help of the mixer valve
– "External sensor value correction" function.
4.1.1 Operation
When the general switch is activated the boiler is powered
with electricity. The blue bar (4) on the control panel lights
up. The symbols, "- -" message and the system pressure are
shown correctly on the screen. To turn the boiler on or off press
button T then button V to select "WINTER mode" or button
U to select "SUMMER mode". The value of the delivery sensor
detected at that moment appears on the display.
m
CAUTION
When the display is not backlit (off), the first press on
each function button serves to backlight it (turn it on);
the second press to carry out the command.
When heat is requested from the systems or the storage tank,
if there is one, the control panel automatically carries out the
functional checks, and electrically powers the gas valve and
ignition transformer to turn on the flame. This is how automatic
operation of the boiler begins. When the request for heat is
fulfilled the flame goes out, but the fan and the circulation pump
remain in operation to carry out post-ventilation and post-
circulation at the end of which they stop and wait for the next
request for heat.
4.1.2 Domestic Hot Water (DHW)
Domestic hot water can be produced if the system has a dhw
circuit with a storage tank. The dhw system can be created
either upstream or downstream of the water shut-off valve. The
installation company is responsible for choosing and paying for
all the systems' components and devices.
