installation of the fan coils and
relevant accessories should be
performed by a technician who has the
necessary technical and professional
expertise to install, modify, extend and
maintain systems, and who is able to
check the systems for the purposes of
safety and correct operation.
WARNING: install a device, main
switch, or electric plug so you can
fully disconnect the device from the

The water, condensate discharge
and electrical circuit ducts must be
provided for.
The fan coil must be installed in such a
position that the air can be distributed
throughout the room and so that there
are no obstacles (curtains or objects) to
the passage of the air from the suction
louvers.
The fan coil should be installed in such
a way as to facilitate routine (filter
cleaning) and special maintenance
operations, as well as access to the
air drain valve on the side of the unit
frame (connections side).
Do not install units in rooms where
there are inflammable gases or acid
or alkaline substances that could
irretrievably damage the aluminium-
copper heat exchanger or the internal
plastic parts.
Do not install the unit in workshops or
kitchens where the oil vapours mixed
with the treated air can be deposited
on the exchange coils, reducing their
performance, or on the parts inside the
unit, damaging the plastic parts.
The FCXI_P unit is prepared for
connection with air ducting. The
maximum speed on FCXI_P fan coils
can be increased by changing the
settings of the motor dip switches.
There are 2 LEDs on the Inverter card
(Alarm / Power) that indicate the unit's
operating status.
The table below shows how to decode
the messages.

If a three-way valve is installed, the
minimum water temperature sensor
can be installed in two locations:
- i n
MANDATORY if the thermostat is
connected to a system with centralised
control or monitoring device (example:
VMF-E5);
- on the delivery pipe up stream of the
valve.
Check the thermostat manual before
choosing the location of the minimum
water temperature sensor, according
to the preferred control logic. The
thermostat may need the settings of the
dip-switches changed.
WA R N I N G : A f t e r c o m p l e t i n g t h e
installation check the operation of the
condensate discharge system, the seal
of the hydraulic fittings, insulation
of ducts and pipes. Then perform a
