WARNING: The fancoil is connected to
the power supply and a water circuit.
Operations performed by persons
without
the required technical skills can lead
to personal injury to the operator or
damage to the unit and surrounding
objects.
DANGER: never switch the appliance on
without having re/mounted the fan coil
casing.
The ultra-violet radiation emitted
from the bulbs inside is dangerous and
can cause conjunctivitis, burns and
dermatitis.
The device has safety micro switches
that prevent functioning if the casing
and filter are missing.
DANGER: do not tamper with the micro
switches as this would make functioning
of the fan coil unsafe..
FUNCTIONING ANOMALIES
In the case of functioning anomalies,
remove the voltage from the unit
and then re-apply it and re-start the
appliance. If the problem persists, call
the area after-sales service immediately.
ONLY POWER THE FAN COIL USING
230 VOLT, SINGLE-PHASE, 50 Hz
The fan coil may undergo permanent
damage if different electric power
supplies are used.
DO NOT PULL THE ELECTRIC CABLE
It is very dangerous to pull, step on,
crush or fix the electric power supply
cable using nails or staples.
The damaged cable can cause short
circuits and injury to persons.
DO NOT INTRODUCE OBJECTS INTO
AIR VENTS
Do not introduce any type of object into
the air outlet slots.
This could cause injury to persons or
damage the fan.
NEVER USE THE FANCOIL FOR
APPLICATIONS FOR WHICH IT WAS
NOT DESIGNED
Do not use the fancoil in husbandry
applications (e.g. incubation).
AIR THE ROOM
Periodically air the room in which
the fancoil has been installed; this is
particularly important if the room is
occupied by many people, or if gas
appliances or sources of odours are
present.
CORRECTLY ADJUST THE
TEMPERATURE
Room temperature should be regulated
to ensure maximum comfort to persons
present, particularly in the case of the
elderly, infants and invalids. Prevent
temperature fluctuations between
indoors and outdoors greater than 7 °C
during summer.
Note that very low temperatures during
summer will lead to greater electricity
consumption.
ORIENT AIR FLOW CORRECTLY
Air delivered by the fancoil should
not be oriented directly at people;
even if air temperature is greater than
room temperature, it can cause a cold
sensation and consequently discomfort.
DO NOT USE HOT WATER
When cleaning the indoor unit, use rags
or soft sponges soaked in warm water
(no higher than 40°C).
Do not use chemical products or sol-
vents to clean any part of the fancoil.
Do not splash water on interior or exte-
rior surfaces of the fancoil; danger of
short circuit.).
PERIODICALLY CLEAN THE FILTER
Frequent cleaning of the filter will ensure
more efficient unit operation.
Check whether the filter requires cle-
aning; if it is particularly dirty, clean it
more often.
Clean the filter frequently. Use a vacuum
cleaner to remove built up dust.
After cleaning and drying the filter, fit it
on the fancoil by following the removal
procedure in reverse order.
The normal wear of the germicidal lamp
and of the filter are not covered by war-
ranty.
SPECIAL CLEANING
The removable drip tray and fan volute
ensure thorough cleaning of the unit (by
specifically trained personnel), essen-
tial for installations in venues subject to
crowding or in those with special hygie-
ne requirements.
IT IS NORMAL
During cooling, water vapour may be
present in the air delivery of the fan coil.
In the heating function it might be
possible to hear a slight hiss around the
fan coil. Sometimes the fan coil might
give off unpleasant smells due to the
accumulation of dirt in the air of the
environment (especially if the room is
not ventilated regularly, clean the filter
more often).
During the operation, there could be
noises and creaks inside the device, due
to the various heat expansions of the
elements (plastic and metallic), but this
does not indicate any malfunctioning
and does not cause damage to the
unit unless the maximum input water
temperature is exceeded.

FCX - - FAN COIL
The fan coil units treat room air during
summer and winter seaqsons.
The FCX fan coil concentrates
high technological and functional
characteristics that make it the ideal
climate control unit for all types of
rooms. The supply of climate controlled
air is immediate and distributed
throughout the room;; FCX generates
heat if included in a heating system with
boiler or heat pump but may also be
used in summer as an air conditioner if
the heating system has a water chiller..
The removable drip tray and fan
volute ensure thoroug cleaning of the
unit essential for installations in venues
subject to crowding or in those with
special hygiene requirements.
The quietness of the new centrifugal fan
assembly is such that at normal speed of
use you cannot hear when the FCX cuts
in.
The FCX fan coil has been designed to
meet all system requirements thanks to
its extensive range of accessories.
The AERMEC fan coil versions without
control panels can be combined to an
AERDOMUS central control unit.
Full respect for accident prevention
regulations
Congratulations on your purchase of the Aermec FCX fan coil.
Made with materials of superior quality in strict compliance with safety regulations, the "FCX " is easy to use and
will have a long life.

COMPONENTI PRINCIPALI
CONTROL PANEL
The control panel is located under the
grill positioined at the right of the fan
coil.In A, AS, ACB, ACT, APC and U
(62U, 82U e 102U) versions, the panel
can be protected from tampering by
using a screw to block the cover door.
In the AS and U versions, the controls
panel (accessory) can be installed on the
fan coil or on the wall.
In versions P, PO and PE, the controls
panel (accessory) can be installed only
on the wall.
The AERMEC fan coil versions without
control panels can be combined to a
HSH AERDOMUS central control unit
with or without connection cables.
Before selecting, consult the control
panels features.
FCX A
WITH MANUAL SELECTORS :
fan coil equipped with control panel for
use and selcting the fan speed.
FCX ACT e APC
WITH ELECTRONIC MULTIFUNCTION
THERMOSTAT :
fan coils equipped with multifunction
electronic thermostat control panels,
the fan coils FCX ACT and FCX APC
are supplied ready for use with standard
configuration, but the installer can adapt
them the special requirements of the
system with the appropriate accessories
and personalising the functions by acting
on the internal Dip-Switch.
The controls are prompt but if valves are
presence they could delay.
System types
The FCX-ACT fan coils have been
designed for systems with 2 pipes, in the
following versions:
- without valve;
- with water valve (VCF);
- with electrical resistance (RX);
- with electrical resistance (RX) and valve
(VCF);
- with hot water battery (BV) and 2 valves
(VCF).
FCX APC : fancoils with
PLASMACLUSTER designed for 2-pipes
plant, in the following models:
- without valve;
- with water valve (VCF);
Ventilation
The three-speed ventilation can
be controlled either manually or
automatically.
For systems with valve and Water Probe
installation upstream of the valve there
may be a delay (delayed ventilation up
to 2’40” max) between the valve start-up
and the fan activation (exchanger pre-
heating).
- manually with the selector in V1, V2 e
V3 position (the fan coil is used with on
off cycles on selected speed);
- automatically with the selector
in AUTO position (the fan speed is
controlled by the thermostat according
to the room temperature)
Change over
The thermostat automatically changes
over from Heating/cooling mode.
Change over is based on the water
temperature detected in the system. It is
possible to choose between two change
over modes by changing the settings on
the DIP switch :
- only minimum/maximum temperature
control;
- with minimum/maximum temperature
control and the preheating of the coil
(fan delayed for a maximum of 2’40”).
Only systems with water probes
positioned downstream of the valve
or with a two way valve, change over
occurs on the air side by acting on
the temperature selector; this setting
allows the fan coil to be used in
systems with two way valves but is not
advised because it reduces the use of
the electronic thermostat (the heating/
cooling modes displayed by the led
are altered depending on the selected
temperature and of the air temperature
in the environment.
Water temeperature controls
The thermostat enables
ventilatsolamenteon only if the water
temperature is suited to Hetaing or
Cooling mode.
The enabling threshold is 35°C or
39°C for Heating and 17°C or 22°C for
Cooling and can be configured by the
Dip-Switch.
The control panels signal the situation
when the water temperature is not
adequate to the function mode set by
means of the alternate flashing of the
pink C led with red or blue depending
on the relative active modes.
If a three way valve is inserted with a
water probe as per standard, it must be
replaced with the SW3 accessory in
which the bulb must be positioined on

the delivery pipe upstream of the valve.
Valve control
The valve can be controlled in two
ways::
- optimised: uses the fan coil capacity
in Heatingto produce heat even with
ventilation off and in Cooling for a
continuous ventilation controlling the
room temperature by means of a valve;
- normal: the valve opens and closes in
correspondance with the switch on and
switch off of the fan coil.
Emergency mode
In case of probe troubleshooting SA, the
thermostat enters in emergency mode,
indicated by a flashing led (D) yellow. In
this condition the thermostat behaves as
follows::
- with selector (A) in OFF position the
water valave is closed and the fan is off.
- with selector (A) in AUTO position,
V1, V2 and V3 the water valve is always
open and the fan performs on off cycles;
in this situation, the power provided by
the terminal is manually controlled by
selcetor (B): turning towards the right
the duration of the On cycle increases;
turningn towards the left it reduces.
FCX ACB
WITH SIMPLIFIED ELECTRONIC THERMOSTAT:
fan coil equipped with control panel
with electronic room thermostat for
controlling switch on and switch off of
the fan.
The control panel controls the function
of the fan coil in order to maintain the
set room temperature. It allows the
electronic adjustment of the temperature,
manual speed change on the fan,manual
function selection in Heating or Cooling
mode (manual change over).
The room probe temperature is located
bext to the “AERMEC” plate.
It is not possible to couple the thermostat
with a water temperature probe.
If the power supply is cut, the fan coils
restarts resetting the previous modes set
The controls are prompt if the room
temperature allows it. Water temperature
control of the system is not foreseen
Type of system
The fan coil series FCX ACB are designed
for two pipe systems :
- without valve;
- with water valve (VCF);
Ventilation
The 3 speed fan is manually controlles

CRITERIA OF CHOICE
The versions with high cabinet (A, AS,
ACB, ACT and APC) have intake from
below and can be used for vertical wall-
hung or floor installation using the rele-
vant skirting (accessory ZX). The acces-
sory SE (external air damper) where
requested, also allows, to change the
environment air.
The versions with universal cabinet (U
and UE) have front intake and can be
vertically wall-hung or installed hori-
zontally on the ceiling.
The suspended versions (P, PPC, PO and
PE), without cover cabinets and intake
from below, are suitable for vertical or
horizontal installation.
In the case of ducted installations where
the loss of load of the channel is rele-
vant, the PO version (with multi-speed
enhanced motor) allows to obtain the
static pressure necessary to guarantee a
correct air flow rate.
The PO version is available with coils
with 3 and 4 rows.
The AS, U, UE versions require coupling
with a control panel to be applied insi-
de or outside, consult the features and
the compatibility of the control panels
supplied as accessories.
The P, PE and PO require coupling with
a control panel to be applied outside,
consult the features and the compati-
bility of the control panels supplied as
accessories.
The PPC version must be coupled to
panel PXA E.
The other versions of fan coil are sup-
plied with incorporated control panel.
Some control panels can control a net-
work of fan coils if they are combined
with the SIT3 and SIT5 interface board
supplied as an accessory.
In the versions without control
panels, the AERMEC fan coils can all
be coupled to the centralised HSH
AERDOMUS control system with wired
or wireless connection.
The main technical data of the FCX are
summarised in the tables.
The sensitive and total cooling capa-
city at maximum speed depending on
the temperature of the inlet water, its
heat drop and the dry and wet bulb
temperatures of the air respectively for
sensitive capacity and total capacity for
the versions with coils with 3 rows are
stated in the table. The efficiency at ave-
rage and minimum speed is obtained by
multiplying the table values by the cor-
rective factors indicate. For the versions
with 4 rows, they are obtained by multi-
plying the table values by the corrective
factors indicated for every speed.
The water side pressure drop for the
coils with 3, 1 and 4 rows is respective-
ly stated in the graphics.
The correction factors in functioning
with glycoled water in cooling mode
and in heating mode are stated in the
graphics per percentages of glycol of
10%, 20% and 35%.
The heating capacity of the coils with 3,
4 and 1 row (accessory BV) depending
on the water flow rate and the tempe-
rature difference between inlet water
and inlet air is stated in a graphical
form and is referred at maximum speed.
Performance at average and minimum
speed is obtained by multiplying the
values obtained from the graphics at
maximum speed by the indicated cor-
rective factors.
The sensitive and total cooling capaci-
ties of the direct expansion coils (FCX
PE) depending on the evaporation tem-
perature and the dry and wet bulb tem-
peratures of the air entering are stated in
the graphical form respectively for total
and sensitive capacity and are stated at
maximum speed. Performance at ave-
rage and minimum speed is obtained
by multiplying the values obtained from
the graphics at maximum speed by the
indicated corrective factors.
For the ducted, suspended versions
(P-PE-PO) the performance stated above
must be intended as referring to air flow
rates equal to those of corresponding
models of other versions (A-U) at maxi-
mum speed (nominal flow rate).
The head of the suspended versions,
depending on the air flow rate and fan
speed, are stated in table form. The cur-
ves are indicated for every speed.
For dimensioning of the ducted, suspen-
ded versions, it is recommended to pro-
ceed as follows: select the size which,
in nominal flow rate conditions, have
immediate power that is higher than
that requested; trace the curve of the
channel pressure drop on the flow rate-
static pressure diagram relative to the
machine in question, thus identify the
functioning points of the machine at
the different speeds. On the basis of the
flow rate values corresponding to the
above-mentioned points, the corrective
factors are finally obtained that allow to
calculate the power yielded in real air
flow conditions. The above-mentioned
procedure allows, in the case of multi-
speed versions, to appropriately choose
the speed to be set.
The sound power and sound pressu-
re level of the fan coils at the various
speeds is stated in separate tables for
the versions with 3 rows and versions
with 4 rows. For ducted, suspended ver-
sions, the sound power level is expres-
sed depending on the air flow rate and
static pressure and is represented using
graphics.
A wide range of accessories is avai-
lable for FCX series fan coils, someti-
mes some of them cannot be used at
the same time. The compatibility of the
accessories with the selected fan coil
must be checked. The manual contains
the description, drawing and compatibi-
lity of each accessory.
The information regarding installation
is inserted in the manual supplied with
every fan coil and every accessory. This
manual is limited to general information
in order to perform correct installation.
There are also drawings with dimen-
sions of the fan coils and wiring dia-
grams with connections to the control
panels.

To prevent the formation of condensation on the exterior of
the unit while the fan is operating, the average water
temperature should not drop beneath the limits shown in the
table below, determined by the thermo-hydrometric ambient
conditions.
These limits refer to unit operation with fan at minimum speed.
In case condensation is formed on the exterior of the unit
if cold water circulates through the coil while the fan is off
for prolonged periods of time, it is advisable to fit the
additional three-way valve.
