7 DESCRIPTION OF THE APPLIANCE
7.1 Characteristics
Brava Slim HE R
are last generation condensing wall mounted
boilers which
Sime
has produced for heating ONLY. Models
Brava Slim HE R i are designed for installation in rooms, while
models
Brava Slim HE R e
are designed specifically for outdoor
installation, protected against atmospheric agents. The main
elements choices made by
Sime
for the
Brava Slim HE R
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, with respect to the room
where the boiler is installed
– the command and control microprocessor electronic board
provides efficient management of both heating and hot water
production. It can also be connected to a remote control
with an Open Therm protocol or to room thermostat and/or
external sensor. If connected to an external sensor, the boiler
temperature varies on the basis of the external temperature
according to a selected optimal climatic curve providing
significant energy and economic savings.
Other special features of the
Brava Slim HE R
boilers are:
– use of a smoke probe to control the relative temperatures. If
the temperature exceeds 110°C the boiler will shut down in
safety status, requiring intervention of the Technical Service
department of qualified professional personnel
– 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 "PAR 10" and , if there
is an external sensor, if the external temperature falls below
the threshold of the value set at parameter "PAR 11"
– 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
parameters and combustion efficiency
– domestic hot water comfort function which allows the time
necessary for the hot water to become available to be reduced
and ensures that the temperature is stable
– screen display of the operating and self-diagnostic
parameters with error code display when the fault occurs.
This makes repair interventions easier and allows appliance
operation to be restored correctly.
7.2 Check and safety devices
The
Brava Slim HE R
boilers are equipped with the following
check and safety devices:
– thermal safety thermostat 100°C
– 3 bar (300 kPa) relief valve
– heating water pressure transducer
– delivery sensor
– DHW sensor
– smoke flue gas probe.
NOTE:
the proper fan operation of this boiler is checked
electronically from the control panel. Then the use of an air
pressure switch is not required.
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.
7.3 Identification
The Brava Slim HE R boilers can be identified by means of:
1 Packaging label:
this is located on the outside of the
packaging 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 specification, appliance
performance and any other information required by law.
