DESCRIPTION OF THE APPLIANCE
5.1
Characteristics
UNIQA REVOLUTION 25
are high-performing, latest-generation,
low-NOx, wall-mounted boilers which
Sime
has produced for
heating and domestic hot water production. The main elements
choices made by
Sime
for the
UNIQA REVOLUTION 25
boilers are:
– the low NOx burner combined with a copper heat exchanger,
which operates at the same time as the heat pump, for space
heating, and a rapid heat exchanger for domestic hot water
(DHW) production
– a “type C” combustion chamber, sealed off from the environ-
ment in which the boiler is installed
– the microprocessor electronic control board, which makes
the heating and domestic hot water production system easier
to manage. The appliance has just one heating request input,
which ambient thermostats or a remote control can be con-
nected to. In the latter case, the boiler temperature varies on
the basis of the external temperature, according to the se-
lected optimal climatic curve. This provides significant energy
and cost savings.
Other special features of the
UNIQA REVOLUTION 25
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 "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
– 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 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
UNIQA REVOLUTION 25
boilers are equipped with the follow-
ing check and safety devices:
– thermal safety sensor 100°C
– 3 bar relief valve
– heating water pressure transducer
– delivery sensor
– DHW sensor
– refrigerant gas high-pressure pressure switch
– air evaporator inlet 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
UNIQA REVOLUTION 25
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 sav-
ings 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.
