WARNING: OMNIA fan coils are designed for
indoor use.
WARNING: the fan coil is connected to power
supply and 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.
WARNING: components sensitive to static elec-
tricity may be destroyed by discharge notably
lower than those at the human perception
threshold. These discharges form when you
touch a component or electric contact of a unit,
without first discharging accumulated static
electricity from your body. The damage caused
to the unit by an overvoltage is not immediately
evident - it only appears after a certain period of
operation.
STATIC ELECTRICITY ACCUMULATION
Any person not connected in a conductive man-
ner with the electronic potential of his surround-
ing environment can accumulate electrostatic
charges.
STANDARD PROTECTION AGAINST ELECTROSTATIC
CHARGES
Earthing quality
When working with units sensitive to electrostatic
electricity, ensure that people, workplaces and
unit casings are correctly earthed. This will pre-
vent the formation of electrostatic charges.
Avoid direct contact
Only touch the element exposed to electrostatic
risk when absolutely essential (e.g. for mainte-
nance).
Touch the element without coming into contact
with either the contact pins or the wire guides.
If you follow this rule, the energy of the electro-
static charges cannot reach or damage the sensi-
tive parts.
Before taking measurements on the unit, it is nec-
essary to discharge all electrostatic charges from
your body: to do this, just touch an earthed metal
object. Only use earthed measuring instruments.
POWER THE FAN COIL ONLY WITH 230V, SINGLE
PHASE VOLTAGE
Any other type of power supply could permanently
damage the fan coil.
DO NOT USE THE FAN COIL IMPROPERLY
Do not use the fan coil for animal husbandry
applications (e.g. incubation).
AIR THE ROOM
Periodically air the room in which the fan coil has
been installed. This is particularly important if the
room is occupied by many people, or if gas appli-
ances or sources of odours are present.
ADJUST TEMPERATURE ADEQUATELY
The room temperature should be adjusted in order
to provide maximum comfort to the people in the
room, especially if they are elderly, children or sick
people; avoid differences over 7°C between the
outdoor temperature and the temperature inside
the room in summer.
In summer, a temperature that is too low causes
higher electrical consumption.
CORRECTLY ADJUST THE AIR JET
Air coming out from the fan coil must not reach
people directly; in fact, even if the air is warmer
than the room temperature, it could cause a cold
sensation and result in discomfort.
DURING OPERATION
Always leave the filter fitted on the fan coil during
operation (otherwise dust in the air could soil the
coil surface area).
WHAT IS NORMAL
In the cooling operation, water vapour may be pres-
ent in the air delivery of the fan coil.
In the heating operation, a slight hiss might be
heard close to the fan coil. Sometimes the fan coil
might give off unpleasant smells due to the accu-
mulation of substances present in the air of the
room (clean the filter more often, especially if the
room is not ventilated regularly).
While the unit is functioning, there could be nois-
es and creaks inside the device due to the vari-
ous thermal expansions of the elements (plastic and
metal), but this does not indicate any malfunction and
does not damage the unit unless the maximum input
water temperature is exceeded.
MALFUNCTIONING
In the event of a malfunction, cut off power sup-
ply to the unit, then restore the power and start
the unit again. If the problem occurs again, call
the local After-Sales Service immediately.
DO NOT TUG THE ELECTRIC CABLE
It is very dangerous to pull, tread on or crush the
electric power cable, or fix it with nails or draw-
ing pins.
A damaged power cable can cause short circuits and
injure people.
DO NOT OBSTRUCT THE AIR OUTLETS BY
PLACING OBJECTS INTO THEM
Do not put anything in the air outlet slots.
This could injure people and damage the fan.

1. DESCRIPTION OF THE UNIT
Omnia Radiant and Omnia Radiant Plus Aermec
innovative solutions
In this particular worldwide market evolution, we are
pleased to present to you OMNIA Radiant, which re-
presents the innovation of the OMNIA AERMEC series,
fan coils especially designed for residential comfort.
1.1. VERSIONS AVAILABLE
1. Omina Radiant (Omnia UL_R).
inherits all the advantages of the OMNIA UL
series, and is characterized by the introduc-
tion of the frontal plate for radiant heating.
1. OMNIA Radiant Plus is provided with the DC
Brushless electric engine, equipped with the
latest Inverter technology, granting the highest
energy efficiency and able to regulate the air
flow through the continuous fan speed modula-
tion. This allows to achieve up to 60% in energy
saving when compared to the traditional On-Off
fan system, in both air conditioning and heating
OMNIA Radiant e Radiant Plus (Omnia UL_RI)
OMNIA Radiant and Radiant Plus offer the following
advantages when compared to the traditional systems:
• the radiant plate combination – the finned coil
allows the best winter comfort with the lower
energy consumption because it provides heating
with lower water temperature: only 45°C against
the about 65°C needed for the traditional radiator.
This not only increases the comfort for the user,
but also significantly increases the overall effi-
ciency in case of heat pumps usage;
• the fan system allows to quickly reach the desired
temperature, meeting the requirement of a fast
start-up;
• the unit can be combined other than the boiler,
also to energy saving heat pumps: air to water,
water to water and geothermic type;
• the electrostatic charge filter standard supplied,
provides pure and clean air;
• during summer Omnia Radiant and Radiant Plus
provide air conditioning and dehumidification in a
fast and efficient way in every room.
1.2. THE FOUR DIFFERENT WORKING MODES OF
OMNIA RADIANT ANNUAL FUNCTIONING
Radiant:
Heating through radiation, comfortable and noiseless,
is granted by the radiant plate placed on the front of
the fan coil cover; if necessary, the triple-fins delivery
head can be closed to increases the heating of the
plate, thus maximizing the radiant effect.
Radiant + Natural Convection
With the triple-fins open, heating through natural con-
vection, obtained thanks to the bigger coil exchange
surface, is added to the radiant heating.
As for the radiant-only mode (see above), the fan
groups are in off mode. This results in acoustic comfort
and energy saving.
Radiant + Forced Convection
The electronic regulation, precise and reliable, conti-
nuously compares the effective indoor temperature
with the desired temperature: whenever the difference
between the two should prove to be too high (e.g.
during the heating system start-up) the software will
lead the fan system start-up. Start-up is fast and effi-
cient and grants significant energy savings especially in
rooms that are occasionally used..
Omnia Radiant during summer provides air conditio-
ning and dehumidification :
Forced Convection
During summer, Omnia Radiant and Radiant Plus provi-
de air conditioning and dehumidification for each room
of the house in a fast and efficient way. Efficiency and
quietness benefit from the quality that has always cha-
racterized the Omnia series.

2. MAIN DESCRIPTION
2.1. RADIANT PLATE
Realized in copper and plate tube to maximize
the radiant surface.
2.2. HEAT EXCHANGE COIL
coil with copper pipe and aluminium fins, held in
place by means of the mechanical expansion of
the pipes
Please note:
The coil cannot be revolved on site. The aach-
ments are only le.
2.3. CABINET
Casing in RAL9002
The casing is made of galvanised steel, varnished
with polyester powders to guarantee high resi-
stance to rust and corrosion.
The feet (accessory) are in plastic, colour
RAL7044.
2.4. ELECTROSTATICALLY PRECHARGED AIR
FILTER
Fire resistance Class 2 (UL 900).
Easily extracble, it is supplied with the fan coil
in a sealed box which should be opened only
upon use. The electrostacally pre-charged
filter combines the normal mechanical filtering
of the air that passes through the filter, with an
electrostac aracon of powder that increases
its filtering considerably.
2.5. ELECTRIC FAN ASSEMBLY
Applied directly to the frame, it consists of extre-
mely quiet, compact, double sucon centrifugal
fans. The electrical motor, protected against
overloading, has three speeds with the running
capacitor always on, directly coupled with the
fans and cushioned with flexible supports. The
fan shrouds can be inspected (an operaon that
can only be carried out by personnel with the
specific technical skills), which also means the
inner parts can be accurately cleaned.
2.6. ELECTRIC MOTOR
2.6.1. Omnia Radiant (UL_R)
Electric motor, protect against overcharges,it has
three speeds, with always switched run capaci-
tor, directly coupled to fans and cushioned with
flexible mounngs.
2.6.2. Omnia Radiant Plus (UL_RI)
The elecric motor “brushless with probes of Hall”
and the control system used in the fan coils arise
from the fusion of the most sofiscated techno-
logies in the field of mechanics and electronics,
enrely developped inside the industrial group.
It is a motor with permanent magnets, with low
inrush current and easy to regualte in speed.
It is not interested from electromagnec disor-
ders.
The fact that it is without brushes permits less
fricons and a reduced wear.
Through a dedicated inverter device it is possible
to control the speed and the rotor couple in a
connous way, simply operang on the stator
currents.
The electric motor is amorzed with elasc
supports and the steel shais mounted on
bushings, the resistance to salt spray is tested
according to the standards ASTM B117/64.
The electric motor presents enormous advan-
tages, compared to tradional motors with
alternave current and with hybrid and inverter
motors (without Hall probes) normally used on
other modulang fan coils:
- Reduced wear
- Possibility of regulang rotaon speed in a
precise and connuous way (0-100%)
- Higher energy efficiency
- Higher reliability and duraon
- Low magnec noise
- Connuous control of rotor posion; this
means higher efficiency and guaranteed and
controlled starng.
- Guaranteed minimum speed 90 rpm (for ther-
modynamic reasons this limit has been carried
to 200 rpm).
2.7. LOADBEARING STRUCTURE
Made of sheet metal of an adequate thickness,
and galvanised to protect against oxidaon.
Equipped with closed cell thermal insulaon with
Class 1 fire resistance.
Holes in the back for wall mounng.
2.8. HEAD WITH ADJUSTABLE FINS
Colour RAL7044
With the deflector fin fully closed, the tripping
of the microswitch stops venlaon thereby
interrupng any further heat exchange with the
environment.
The control panel is also housed in the head, and
is protected by a flap
2.9. CONDENSATE DRAIN
Each device is equipped with condensate drain.
2.10. DIVERTING VALVE
On the inlet water side there is an ON -OFF diver-
ng valve controlled with electric servocontrol.
Note:
The coil had hydraulic hoses on the left and is not
reversible.

WARNING
Minimum average water tem-
perature
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 air
in the room.
These limits refer to unit operat-
ing with fan at minimum speed.
