DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
Brava One OF
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 OF
– the atmospheric burner combined with a copper heat ex-
changer for heating and a rapid heat exchanger for DHW
– the open combustion chamber which classifies the "Type B"
boiler in relation to the room where it is installed
– 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 Brava One OF 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 and when checking gas
pressure at the nozzles
– 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 Brava One OF boilers are equipped with the following check
and safety devices:
– thermal safety sensor 100°C
– smoke thermostat
– 3 bar relief valve
– heating water pressure switch
– delivery sensor
– DHW sensor.

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.

Identification
The Brava One OF boilers can be identified by means of:
this is located on the outside of the packag-
1
Packaging label:
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 specification, appliance
performance and any other information required by law.

CAUTION
Tampering with, removing or failing to display the
identification plate or carrying out any other operation
which does not allow safe identification of the product
or which may hinder installation and maintenance op-
erations.
