DESCRIPTION OF COMPONENTS
CON TR OL PA NEL
The control panel is housed in the head of
the fan coil, protected by an access flap.
ELECTRONIC THERMOSTAT
OMNIA UL_N is equipped with an
electronic control panel with micro-
processor. It's extremely intuitive and
user-friendly, with just two knobs - one
to increase or decrease the tempera-
ture, and the other to switch on/off
and set the predefined (or automatic)
ventilation speeds.
The response to commands may be
delayed (heat exchanger pre-heating).
THERMOSTAT ELECTRONIC CARD
The box containing the thermostat elec-
tronic card is fixed to the side of the
fan coil.
The electronic card has a dip-switch
for configuration, and connectors for
making the connection with:
- the power supply,
- the earthing,
- the control panel (user interface),
- the fan motor command,
- the valve command,
- the room temperature probe,
- the water temperature probe,
- the fan coil network,
- the external contact,
- the MS external contact.
HEAT EXCHANGE COIL
2-row coil with copper pipe and alu-
minium fins, held in place by means
of the mechanical expansion of the

pipes. The collectors are fitted with
female connections and air vents in
the upper part of the coil. The coil can
be rotated on the worksite.
CABINET
Casing in RAL9002
The casing is made of galvanised steel, var-
nished with polyester powders to guaran-
tee high resistance to rust and corrosion.
The feet (accessory) are in plastic,
colour RAL7044.
• ELECTROSTATICALLY PRECHARGED
AIR FILTER
Fire resistance Class 2 (UL 900).
Easily extractible, it is supplied with the
fan coil in a sealed box which should
be opened only upon use. The electro-
statically pre-charged filter combines
the normal mechanical filtering of the
air that passes through the filter, with
an electrostatic attraction of powder
that increases its filtering considerably.
ELECTRIC FAN ASSEMBLY
Applied directly to the frame, it consists
of extremely quiet, compact, double
suction centrifugal fans. The electri-
cal motor, protected against overload-
ing, has three speeds with the running
capacitor always on, directly coupled
with the fans and cushioned with flex-
ible supports. The fan shrouds can be
inspected (an operation that can only
be carried out by personnel with the
specific technical skills), which also
means the inner parts can be accu-

rately cleaned.
LOAD-BEARING STRUCTURE
Made of sheet metal of an adequate
thickness, and galvanised to protect
against oxidation. Equipped with
closed cell thermal insulation with
Class 1 fire resistance.
Holes in the back for wall mounting.
Each device is equipped with a con-
densate collection tray that can be
removed for cleaning (this operation
can only be carried out by personnel
with the specific technical skills).
CONDENSATE DISCHARGE
Every device is fitted with a tray for col-
lecting condensation, with a connec-
tion for draining condensation pro-
duced by the unit in cooling mode.
WATER CONNECTIONS
The connections, located on the left
hand side, are female. The possibility
exists for rotating the battery on the
construction site. \.
HEAD WITH ADJUSTABLE FINS
Colour RAL7044
With the deflector fin fully closed, the
tripping of the microswitch stops ven-
tilation thereby interrupting any further
heat exchange with the environment.
The control panel is also housed in the
head, and is protected by a flap.
