CON TROL PA NEL
The control panel (accessory) can only
be installed on the wall.
The AERMEC fan coil versions without
a control panel can all be combined
with the HSH AERDOMUS centralised
control system, using wired or wireless
connections.
Consult the control panel characteristi-
cs before selecting a panel.
ELECTRIC FAN ASSEMBLY
This consists of double suction cen-
trifugal fans with lengthways blades to
obtain a high air flow with a low num-
ber of revs. The electrical motor, protec-
ted against overloading, has three spe-
eds with the running capacitor always
on, directly coupled with the fans and
cushioned with flexible supports.
BEARING STRUCTURE
Made of galvanised sheet metal of an
adequate thickness. Hole in the back
for wall mounting. A fan cover panel is
available for front-mounted ceiling units.
Each unit is equipped with a condensate
collection tray.
CONDENSATE DRAIN
Every device is fitted with a tray for col-
lecting condensation, with a connection
for draining condensation produced by
the unit in cooling mode. When there
are differences in levels, it is possible
to apply the accessory (DSC4) outside
the unit, complete with pump and water
level control device.
PLUMBING CONNECTIONS
The connections, located on the left
hand side, are female. The coil may also
be rotated.
DESCRIPTION OF COMPONENTS
SELECTION CRITERIA
The Coanda effect fan coil of the VEC
range must be installed in suspended
ceilings and is completed with the obli-
gatory accessory VEC20GL.
The accessory VEC20GL consists of
the panel with suction from below and
delivery with adjustable diffusers that
allow the air to be distributed throu-
ghout the room, taking advantage of the
COANDA effect.
VEC must be combined with a con-
trol panel to be mounted on the wall.
Consult the characteristics and compa-
tibility of the control panels supplied as
an accessory.
Some control panels can control a
network of fan coils if they are used in
combination with the interface cards
SIT3 and SIT5 supplied as accessories.
The AERMEC fan coil versions without
a control panel can all be combined
with the HSH AERDOMUS centralised
control system, using wired or wireless
connections.
The main technical data of the VEC fan
coils are summarised in the tables.
The table shows the sensible and total
refrigerating yield at maximum speed,
on the basis of the inlet water tempe-
rature, its temperature change, and the
dry bulb and wet bulb air temperature,
for sensitive yield and total yield respec-
tively, for versions with a 3-row coil.
Performance levels at average and mini-
mum speed are obtained by multiplying
the values by the correction factors indi-
cated.
The water side pressure drops are
shown in the diagrams.
The correction factors when the unit
operates with glycol water for cooling
and heating function modes are shown
in the graphs in percentages of glycol of
10%, 20% and 35%.
The heating capacity yield, on the
basis of the water flow rate and the
difference in temperature between the
incoming water and the incoming air, is
represented in a graph and refers to the
maximum speed. Performance levels at
average and minimum speed are obtai-
ned by multiplying the values shown on
the graph (at maximum speed) by the
correction factors indicated.
The pressure level and sound output
of the fan coils at the various speeds are
shown in the tables.
The installation information is inclu-
ded in the manuals supplied together
with each fan coil or its accessory. This
manual is limited to provide general
information in order to obtain a correct
installation; it also contains drawings
with fan coil dimensions and the wiring
diagrams with the connections to con-
trol panels.
