5 DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
Vera HE
are last generation condensing wall mounted boilers
which
Sime
has produced for heating and domestic hot water
production. The main design choices made by
Sime
for the
Vera
HE
boilers are:
– the total pre-mix microflame burner combined with a steel
heat exchanger for heating and a rapid heat exchanger for
DHW
– the sealed combustion chamber which can be classified "Type
C" or "Type B" in relation to the room where the boiler is in-
stalled, depending on the smoke outlet configuration adopted
during installation
– the command and control microprocessor electronic board
not only allows a better management of the heating system
and the system for domestic hot water production but it can
also be connected to air thermostats or a remote control (with
an Open Therm protocol), an auxiliary sensor for the connec-
tion of any possible solar kits or to an external sensor. If this is
the case, the boiler temperature varies on the basis of the ex-
ternal temperature according to the selected optimal climatic
curve allowing for significant energy and economic savings.
Other special features of the
Vera HE
boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the
threshold of the value set at parameter "tS 1.0" and , if there
is an external sensor, if the external temperature falls below
the threshold of the value set at parameter "tS 1.1".
– the anti-blocking function of the pump and diverter valve, this
activates automatically every 24 hours if no request for heat
has been made
– the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the pa-
rameters and combustion efficiency
– screen display of the operating and self-diagnostic parame-
ters with error code display when the fault occurs. This makes
repair interventions easier and allows appliance operation to
be restored correctly.
5.2
Check and safety devices
The
Vera HE
boilers are equipped with the following check and
safety devices:
– thermal safety thermostat 100°C
– 3 bar relief valve
– heating water pressure switch
– delivery sensor
– DHW sensor
– smoke flue gas probe.
d
IT IS FORBIDDEN
To commission the appliance with safety devices
which do not work or which have been tampered with.
a
WARNING
Safety device may only be replaced by professional
qualified personnel using
Sime
original spare parts.
5.3
Identification
The
Vera 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 Energy Efficiency Label:
this is positioned on the outside of
the packaging to notify the User of the level of energy sav-
ings and reduced environmental pollution produced by the
appliance.
3 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.
