DESCRIPTION OF THE APPLIANCE

1.1

Characteristics

Brava One 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 Brava One 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 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 a remote control with an Open Thermo
protocol or to air thermostats or to an external sensor. If
connected to an external sensor, the boiler temperature va-
ries 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 One 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 the-
re 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
– screen display of the operating and self-diagnostic parame-
ters with error code display when the fault occurs. This ma-
kes repair interventions easier and allows appliance opera-
tion to be restored correctly.

The Brava One HE boilers are equipped with the following
check and safety devices:
– thermal safety thermostat 100°C
