27. DESCRIPTION OF THE UNIT
The FCXI series units are fan coil terminals to treat
air indoors, both during winter and summer.
The FCXI fan coil concentrates high technological
and functional features that make it ideal to
heat and cool all environments. The supply of
heated or cooled air is immediate and distributed
throughout the room; FCXI generates heat if
included in a heating system with boiler or heat
pump. However, it may also be used in the summer
as an air conditioner, if the heating system has a
water chiller.
The fan coil fully complies with accident-

29. DESCRIPTION OF COMPONENTS
CONTROL PANEL
The AERMEC fan coils can be integrated in the VMF
System in versions without control panel.
Refer to the control panel features in the
"Accessories "chapter.
HEAT EXCHANGE COIL
Coil made with copper pipes and aluminium lou-
vers blocked by the mechanical expansion of the
pipes. The collectors are equipped with female
connections and air vents on the upper part of
the coil.
FCXI configuration for 2-pipe systems.
- Standard main coil (reversible).
- Larger main coil (reversible).
FCXI configuration for 4-pipe systems.
- Standard main coil combined with VCF_X4 valve
accessories.
(Reversible on site).
- Larger main coil combined with VCF_X4 valve
accessories.
(Reversible on site).
- Standard main coil coupled with BV coil acces-
sory.
(Reversible on site).
The hydraulic connections of the BV and BVD
versions, up to size 50, are not reversible during
installation. Specify the connection side when
placing the order.
FILTERING SECTION
Easy to remove, it is manufactured with renew-
able materials and it can be cleaned via vacuum.
The versions without cabinet are equipped with
class G2 filters.
PROTECTIVE CABINET
IFCXIIJ 1501 - 5386400_00
prevention standards.
The tray and the augers of the inspectionable
fans allow even the internal parts to be cleaned
accurately.
Particularly silent centrifugal ventilation unit.
The FCXI fan coil has been designed to meet
every system requirement, thanks also to the
accessories supplied.
In particular, the fact that the unit can be
integrated in the VMF system gives you control
over the individual fan coil with accessories up
to the management of the fan coil inserted in

Casing (RAL9002 colour)
Flow and suction grids (RAL7044 colour)
The casing is made with galvanised steel sheet
metal and painted with polyester powder to guar-
antee high resistance to rust and corrosion.
The feet (accessory) for the units with casing are
made of plastic (RAL7044 colour).
BRUSHLESS ELECTRIC MOTOR WITH INVERTER
CONTROL
The "brushless electric motor with Hall sensors"
and the control system used in the AERMEC
FCXI fan coils is a combination of sophisticated
technologies in the field of mechanics and
electronics entirely developed within the
industrial group. This is a permanent magnet
motor with low starting current and easy speed
adjustment. Not affected by electromagnetic
interference. The fact that it is brushless allows
lower friction and less wear. With the special
inverter device, it is possible to control the speed
and torque of the rotor continuously, just by
means of the stator currents. The electric motor
is cushioned with elastic supports and the steel
shaft is mounted on bushings and resistance
to salt fog is tested in accordance with ASTM
B117/64.
The "brushless electric motor with Hall sensors"
used in AERMEC FCXI modulating fan coils has
huge advantages over conventional AC motors
and hybrid inverter motors (without Hall sensor)
normally used on other modulating fan coils:
- Reduced wear and tear
- The possibility to regulate the rotation speed in
a precise, continuous manner (0-100%)
- Higher energy yields
- Longer life and greater reliability
- Low magnetic noise
complex networks.
The VMF (Variable Multi Flow) system can
manage a complete hydronic system, consisting
of a chiller/heat pump, a boiler, a fan coil network
(multi-speed or continuous speed modulation)
divided into up to 64 areas, up to 12 circulation
pumps and up to 3 heat recovery units with air
quality probes. This optimises air conditioning and
heating performance and guarantees comfort and
energy saving.

- Continuous monitoring of the rotor position
implies greater efficiency, and guaranteed and
controlled starting
- Guaranteed minimum speed 90 rpm (for
thermodynamic reasons, this limit was raised to
200 rpm).
SUPPORT STRUCTURE
It is made with galvanised steel sheet metal of
suitable thickness. There are holes to fasten the
appliance on the wall located on the rear part.
For the models without cabinet, the closing panel
of the ventilation unit is mounted on the front.
The feet (accessory) for the ducted units are
made of galvanised steel sheet metal.
CONDENSATE DRIP TRAY
Every fan coil is equipped with a condensate drip
tray for installations with vertical units.
The fan coils of the FCXI U, P, PBV, PBVD fan coils
are equipped with a second tray, for installations
with horizontal unit.
All the condensate drip trays are thermally
insulated and have double drain on the right and
left. Seal the drain that is not used.
CONDENSATE DRAIN
Every fan coil installed to run in cooling mode
must be connected to the condensate drain
system, which must be suitably sized and tilted to
allow the water to flow.
HYDRAULIC CONNECTIONS
The hydraulic connections are female type and
are usually positioned on the left side.
The hydraulic connections must be positioned on
the opposite side of the electric connections.
The coils can be rotated on site (reversible
coil), except for the versions with double circuit
coil (NOT reversible), which must be ordered
