Valves
Technical data for valves with thermoelectric actua-
tor can be found at p. 27.
For the oN-oFF 230 V three-way water valve and
mounting kit with regulating check valve see p. 138.
For the oN-oFF 230 V 2-way valve see p. 139.
Electrical connections
For wiring diagrams see p. 129.
General warnings
Perform electrical connections in accordance
with laws and regulations in force in the country
concerned.
The wiring diagrams do not address protective
grounding or other electrical protection which will
be required under local rules, regulations, codes and
standards or by the local electricity supplier.
Before installing the fan coil, make sure the rated
voltage of the power supply is 230 V / 50-60 Hz.
The power supply is always connected to terminals l,
N and PE on the board.
Maximum power consumption for 230 VAC mains
power operation is as follows:

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
34
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.
All controls for installation on the unit are provided
with a connection cable to the power unit board.

The motor is protected by a thermal contact integrat-
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.
locali.Indice di revisione
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.
