OPERATING LIMITS
Performance values refer to the following conditions:
- at the maximum motor speed;
- the total input power is determined by adding the input power
for the unit and the input power for the accessories connected
and declared in the corresponding manuals.

HOW TO CHOOSE
The main technical data of the FCLI
range are summarised in the tables and
diagrams.
The sensible and total cooling capacities
at maximum speed depending on the
incoming water temperature, thermal
head and the dry bulb and wet bulb
temperature of the air respectively for
sensible and total yield are shown
in the table. The performances at
the average and minimum speed
are obtained by multiplying the
table values by the corrective factors
indicated.
The water side pressure drops are shown
in the diagrams.
The correction factors when the unit
operates with glycol water for cooling
and heating function modes are shown
in the graphs in percentages of glycol of
10%, 20% and 35%.
The heating capacity based on the water
flow rate and temperature difference
between the inlet water and inlet air is
shown in a graphical form and refers to
the maximum speed; the performances
at average and minimum speeds are
obtained by multiplying the values
obtained from the chart at maximum
speed by the corrective factors
indicated.
The pressure level and sound power
of the fan coils at different speeds is
shown in the tables.
A wide range of accessories is
available for the FCLI fan coils, but
in certain cases some of them cannot
be used simultaneously. Check the
accessories are compatible with the
fan coil chosen. The manual contains
a description of each accessory, plus a
drawing and its compatibility.
The installation information is included
in the manuals supplied together with
each fan coil or its accessory. This
manual is limited to provide general
information in order to obtain a correct
installation; it also contains drawings
with fan coil dimensions and the
wiring diagrams with the connections
to control panels.
If the fan coil is working in continuous
cooling mode in an environment
where the relative humidity is high,
condensate might form on the air
delivery and on the outside of the
device. This condensate might be
deposited on any objects underneath
and on the floor.
To avoid condensate on the external
structure of the device while the fan is
functioning, the average temperature
of the water must not be lower than
the limits shown in the table below,
that depend on the thermo-hygrometric
conditions of the external air.
These limits refer to unit operating with
fan at minimum speed.
In order to prevent air stratification in
the room, and therefore to achieve
improved mixing, it is advisable not
to supply the fan coil with water at a
temperature over 65°C.
The use of water at high temperatures
could cause squeaking due to the
different thermal expansions of the
elements (plastic and metal). This does
not however cause damage to the unit if
the maximum water inlet temperature is
not exceeded (see table).
