DESCRIPTION OF THE APPLIANCE

1.1

Characteristics

Brava One BF are last generation low temperature wall mounted
boilers which Sime has produced for heating and domestic hot
water production. The main design choices made by Sime for the
boilers are:
Brava One BF
– the atmospheric burner combined with a copper 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 installed, 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
connection of any possible solar kits or to an external sensor.
If this is the case, the boiler temperature varies on the basis
of the external temperature according to the selected optimal
climatic curve allowing for significant energy and economic
savings.
Other special features of the Brava One BF 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
parameters and combustion efficiency and when checking
gas pressure at the nozzles
– 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.
1.2

Check and safety devices

The Brava One BF boilers are equipped with the following check
and safety devices:
– thermal safety sensor 100°C
– 3 bar relief valve
– heating water pressure switch
– delivery sensor
– DHW sensor.
