GLLI 10
Grille unit with intake and delivery fi lter, with manually
adjustable fins, colour RAL 9010. The accessory also
includes the electric box for the unit.
CONTROL PANEL
The FCLI unit requires an external control panel with
thermostat and ventilation speed control, with a 0-10V
output. For the selection, refer to the list of accessories.
COMPULSORY ACCESSORY
• Standard
FCLI
version, with standard
internal 3-way valve fi tted with fast
connection actuator and visual position
signalling.
•
FCLI_V2
version, with standard internal
2-way valve fi tted with fast connection
actuator and visual position signalling,
suitable for systems with a variable water
fl ow rate.
•
FCLI_VL
version, without an internal
valve.
VERSIONS
The cassette fan coils are available in three
versions, to satisfy all system requirements.
The sizes, performance levels and outer
dimensions are the same as those for the
standard
FCLI
version.
In this manual, versions
FCLI_VL
and
FCLI_V2
will only be referred to when
there are differences compared with the
standard
FCLI
version; otherwise they
will simply be called
FCLI
.
Versions
FCLI_VL
and
FCLI_V2
are
available upon request.
PURPOSE OF THE FCLI CASSETTE-TYPE MODULATING FAN COIL
The fan coil is a room air treatment terminal unit for both winter and summer operation.
The cassette modulating fan coils of the FCLI range with brushless inverter motor differ from traditional fan coils as they offer greater
climate and acoustic comfort, as well as energy savings.
- The set temperature is maintained with
the greatest precision: the continuous
modulation of the fan speed prevents
oscillations caused by changes in speed
or a series of on-off cycles.
- Excellent acoustic comfort: as there are
no sudden changes between the different
speeds, no sound variation is heard when
the unit passes from one speed to another,
or when it passes between off and on. The
type of motor, and the control used, also
allow a minimum rotation speed much
lower than that of traditional models (even
more than 50% lower), so not only is the
average noise level greatly reduced but
above all the impression of actual noise.
(For example, if a traditional fan coil alter-
nates minimum speed cycles and fan "off"
cycles in the bedroom, what we hear is
not the average noise but the noise made
when it is operating at minimum speed.)
- Energy savings: thanks to the use of the
brushless motor, allowing greater effi-
ciency even in normal operating condi-
tions. To make the comparison, we have
created a display stand which we'll use
during trade fairs and events; we've
installed two of our fan coils of the same
size, one with a traditional motor and the
other with a brushless motor. With the
same motor rpm (and therefore the same
air flow rate), the reduction in input power
for the fan coil with a brushless motor
exceeds 50%. The inverter is a system that
automatically reduces the rpm and input,
allowing the fan coil to operate in choked
conditions and thereby producing notable
savings on yearly management costs. The
more efficient distribution system helps to
improve the energy class of the building.
The electronic control of the rpm means
you can guarantee and control the pickup
phase, avoiding those input peaks that
are produced with asynchronous motors
and are typical of this phase. Of course,
these benefits increase in proportion to the
number of FCLI fan coils installed.
ADVANTAGES
Cassette-type fan coil with Inverter for
installation in suspended ceilings, can be
integrated in standard 600x600 panelling.
The FCLI cassette-type fan coil is a room
air treating unit. The FCLI concentrates
high technological and functional
characteristics that make it the ideal
climate control unit for all types of
room. The climatised air is distributed
throughout the room thanks to the
delivery fins facing in four directions.
FCLI generates heat if included in a
heating system with boiler or heat pump,
but may also be used in the summer as
an air conditioner if the heating system
has a water chiller.
The fan coils are designed for 2- and
4-pipe systems.
The unit is installed in a suspended ceiling
with the possibility to send conditioned
air to adjacent rooms and introduce
external air regardless of unit ventilation.
