5 DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
MURELLE.HT
are last generation condensing wall mounted boil-
ers which
Sime
has produced for heating and domestic hot water
production. The main design choices made by
Sime
for the
MUR-
ELLE.HT
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
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 tempera-
ture varies on the basis of the external temperature according
to a selected optimal climatic curve providing significant ener-
gy and economic savings.
Other special features of the
MURELLE.HT
boilers are:
– the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the value
set under parameter "PAR 7" and, where there is an external
sensor, if the external temperature falls below the value set
under parameter "PAR 8"
– 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
– 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 re-
pair interventions easier and allows appliance operation to be
restored correctly.
5.2
Check and safety devices
The
MURELLE.HT
boilers are equipped with the following check
and safety devices:
– thermal safety thermostat 100°C
– 3 bar relief valve
– heating water pressure transducer
– delivery sensor
– return 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
MURELLE.HT
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 savings 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.
