1.2.1 Preliminary checks
a
WARNING
Should it be necessary to access the areas in the bot-
tom part of the appliance, make sure that the system
components and pipes are not hot (risk of burning).
Commissioning of the ALU HE boiler must be carried out by pro-
fessionally qualified personnel after which the boiler can op-
erate automatically. It may, however, be necessary for the sys-
tem manager to start the appliance autonomously after having
turned it off, without involving a technician: for example, after a
holiday.
In such cases it must first be checked that the fuel and water
system isolation valves are open.
1.2.2 Ignition
After having carried out the preliminary checks, proceed as fol-
lows:
–set the main system switch to "ON"
– the blue bar (4) comes on and the screen saved by the elec-
tronic circuit board before the appliance was turned off is
shown on the display.
Example: winter; delivery temperature (40°C); system pressure
(1.3 bar).
ON
Fig. 2
When heat is requested from the systems the boiler automati-
cally carries out:
–the operational checks
– ignition and starts automatic operation.
m
CAUTION
– When the display is not backlit (off), the first press
on each function button serves to backlight it (turn
it on).
– To manually stop the boiler press button T.
– The display will show the following screen.
1.3 Adjusting the delivery temperature
The control panel on ALU HE boilers lets you manually adjust the
delivery temperature on two temperature levels by choosing the
best ones for the systems managed (e.g. 80°C and 50°C).
To adjust the delivery temperature on the first of the two levels:
– press button X(twice if the display isn't backlit). The symbol
uwill be shown on the display
– press buttons Jor Quntil the desired value is displayed
(e.g. 80°C)
– press button Xagain. The symbol xwill be shown on the
display
– press buttons Jor Quntil the desired value is displayed
(e.g. 50°C)
Once the settings are completed, to go back to the starting
screen press button Xor wait for approx. 60 seconds without
touching any buttons.
1.4 Malfunctions
In the event of a fault/malfunction the message "ALL" will ap-
pear on the display with the alarm number and the light bar (4)
will turn red.
Example: “ALL 02” (Low System Pressure Error: less than 0.8
bar).
NOTE: in the case of "ALL 02" , the system can be reintegrated,
when cold, without disconnecting the power supply to be able to
see when the pressure reaches the correct value (be included
in the range 0.8-6.0 bar). The warning disappears when normal
conditions are reset and the boiler starts up again automatically.

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 al-
lows 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 mix-
ing
– a combustion circuit which can be "Type C" (sealed) or "Type
B" (open) with respect to the place where the boiler is in-
stalled, depending on the configuration of the combustion air
inlet 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 installed as single units or in a cas-
cade composed of between two and eight appliances with the
same heating output.
When boilers are connected in a cascade, they communicate
ONLY with the master boiler, treating the cascade as a single
heat generator where:
Cascade output = Boiler output x no. of boilers installed
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 connect-
ed 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” and the “MOD-
BUS interface code 8092278” to communicate via MODBUS with
remote devices. 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 8101595, which is man-
datory 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 val-
ue 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 pa-
rameters and combustion efficiency
–anti-legionella function when a storage tank is used
– automatic adjustment of the ignition output and minimum and
maximum heating output. The outputs are managed automat-
ically by the electronic circuit board to ensure maximum sys-
tem usage flexibility
–dispersal function, so that if the delivery probe detects a tem-
perature of 90°C, the fan runs until it falls to 89°C
–screed drying function, to keep the floor at a pre-set tempera-
ture 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 cor-
rectly on the screen. To turn the boiler on or off press button T
then button Vto select "WINTER mode" or button Uto 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 igni-
tion transformer to turn on the flame. This is how automatic op-
eration 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 instal-
lation company is responsible for choosing and paying for all the
systems' components and devices.
m
CAUTION
The installation company is responsible for choosing
and paying for all the systems' components and de-
vices.
4.2 Check and safety devices
The ALU HE boilers are equipped with the following check and
safety devices:
– thermal safety thermostat 98°C with automatic reset
– system water pressure transducer
– delivery sensor (SM)
– return sensor (SR)
– exhaust sensor (SF)
– air pressure switch
– siphon pressure switch.
d
DO NOT
Do not commission or operate the appliance with safe-
ty devices which do not work or which have been tam-
pered with.

WARNING
Safety device may only be replaced by professional
qualified personnel using
Sime original spare parts.
4.3 Identification
The ALU HE boilers can be identified by means of:
1 Packaging label: this is located on the outside of the packag-
ing and provides a code, the serial number of the boiler and
the bar code
2 Technical Data Plate: this is located inside the front panel of
the boiler and provides the technical data, appliance perfor-
mance information and any other information required by
law in the country where the appliance will be used.
