DESCRIPTION OF COMPONENTS

CONTROL PANEL
The control panel is housed in the head
of the fan coil, protected by an access
flap.
ELECTRONIC THERMOSTAT
OMNIA HL_N is equipped with an elec-
tronic control panel with micropro-
cessor.It's extremely intuitive and
userfriendly, with just two knobs, one to
increase or decrease the temperature,
and the other to switch on/off and set
the predefined (or automatic) ventila-
tion 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 mak-
ing 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 alumin-
ium fans, held in place by means of the
mechanical expansion of the pipes. The
collectors are fitted with female connec-
tions and air vents in the upper part of
the coil. The coil can be rotated on the
worksite.

CABINET
HL_N : Casing in RAL9002
HL_NM : Casing in FIAT656
The casing is made of galvanised steel,
varnished with polyester powders to
guarantee high resistance to rust and
corrosion.
The feet (ZH accessories series) are either
in RAL7044 plastic material to be com-
bined with the HL_N version (RAL9002)
or in RAL7031 to be combined with the
HL_NM version (FIAT656) To select the
feet, please consult the documentation
for the ZH accessories series.
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 electrostati-
cally 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 electrical
motor, protected against overload-
ing, has three speeds with the running
capacitor always on, directly couplet
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 accurately
cleaned.

Made of sheet metal of an adeguate
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 conden-
sate collection tray that can be removed
for cleaning (this operation can only be
carried out by personnel with the spe-
cific technical skills).
CONDENSATE DISCHARGE
Every device is fitted with a tray for col-
lecting condensation, with a connection
for draining condensation produced by
the unit in cooling mode.
WATER CONNECTIONS
The connections, located on the left hand
side, are female. The possibilità exists for
rotating the battery on the construction
site.
HEAD WITH ADJUSTABLE FINS
HL_N : Colour RAL7044
HL_NM : Colour RAL7031
With the deflector fin fully closed, the trip-
ping of the microswitch stops ventilation
thereby interrupting any further heat
exchange with the environment.
The control panel is also housed in the
head, and is protected by a flap.
