Make sure that, in addition to supplying the working
current required by the fan coil, the mains electrical
supply is also able to supply the current necessary to
operate other household appliances and units.
In case of combination of the fan coil with
electronic controllers it must be absolutely
considered that the 0-10 V DC signal will
always and only come from the controller
itself and that it must be applied on the
structure of the fan coil.
Upstream of the unit, a disconnection switch must
be provided and shall have a contact separation in all
poles, providing full disconnection under overvolt-
age category III condition.
The unit must always be earthed.
Always disconnect the electrical power supply be-
fore opening the unit.
The minimum cross section of the electric wires is
0.75 mm².
We recommend the use of a 3G0.75 cable of the har-
monized type <HAR> whose replacement, in case of
damage, must be carried out by qualified personnel.

Connection instructions

The unit is fitted with a connection terminal board
on the internal side panel on the opposite side to the
hydraulic couplings.
To connect, respect the wiring diagrams in this
booklet.
The installer must bring the connecting wires into
the unit through the access points provided:
• wall-mounted, using the rear access point corre-
sponding to the side panel.
• floor-standing, using the recess inside the foot
(MV units with feet only).
• from near the unit in the case of built-in installa-
tions.

The motor is protected by a thermal contact integrat-
0,306
ed in the winding. It stops the motor if overheating
occurs and starts the motor again automatically after
it has cooled down.
The fan coil is provided with a terminal board for
the connection of the electrical feeding, for the fan
speed control, for the valve's control and for the con-
nection with the safety device.
When designing and dimensioning the power
line and protection devices for electronic ap-
pliances with interference suppression filters,
the leakage current must be taken into consid-
eration.
our ECM appliances comply with CEI-EN 60335 as
they have a leakage current of 0.8 mA, below the 3.5
mA permitted limit specified in the standard.
The total leakage current considered must take ac-
count of the number of appliances installed and the
characteristics of any other electrical appliances con-
nected on the same power line.
