Before assembling or using this product, carefully read all the instructions in this manual and be
sure to own all the necessary material for the installation.
Scrupulously follow the instructions in this manual.
1) ASSEMBLY
Once the area of installation is selected, mark the center of the hole to be realized on the wall
Make sure that on internal and external walls there is enough space, for a radius of 15 cm from
the center, thus corresponding to the product overall dimensions. Therefore make sure that,
within this area, there are not any interferences with other walls or non-removable objects.
Hole diameter for installation is Ø160mm
The duct must be installed through the hole, with a slight downward slope of 1° - 2° towards the
outsight to allow proper discharge of condensation.
To use the supplied recessed duct, the thickness of the wall must not exceed 400mm.

26
To install the product, the wall thickness cannot be less than 250mm.
Once obtained the hole, put the recessed duct (6) into the wall.
Make sure that the length of the recessed duct (6) is equal to the thickness of the wall.
The duct must end with the internal and external surfaces of the wall.
The quote “M” cannot be less than 250mm. In this case the wall is not appropriate to install the
product.
Adapt the duct if necessary, to the thickness of the wall with suitable tools, in the best way as
shown below:

27
Once adapted the length of the recessed duct (6) to the exact thickness of the wall, put the
external wall- mounting part (4e) on the external wall as shown in the picture below:
Insert the centering diameter of the wall-
mounting part (4e) inside the recessed duct
(6).
Once centered in the duct, mark the fixing holes on the external wall using the external wall-
mounting part (4e) through a level measure tool to ensure a proper installation as shown in the
picture below:
Make the holes and insert the expansion plug for the wall mounting.
Fix the external wall-mounting part (4e) on the external wall.

28

shown in the pictures below:
2) ELECTRICAL CONNECTIONS
Installation must only be carried out by qualified person. Make sure that the voltage of the
installation room is in compliance with the value declared on the product label.
Make sure that the main electrical supply in the installation room is disconnected before electrical
assembly operations.
Identify the version of the product and carefully read all the instructions related to electrical
connections.
As done by marking the external holes, insert the centering diameter of the internal wall-mounting
part (4i) within the recessed duct (6) as shown in the picture above.
By using a measure level tool, mark and make four holes to fix on the wall the internal wall-
mounting part (4i).

29
Unlike the external wall mounting part, on the internal wall is necessary to bring the power supply
conductors to connect them to the stripped wires supplied with the product.
Provide an output for the wires, as the highlighted area shown in the picture
.
Once the expansion plugs for the wall mounting are inserted, carefully check all the electrical
operation before proceeding with the installation.

30
POWER SUPPLY CONNECTIONS
Before proceeding with the connection, make sure that the wires (Live and Neutral) are inside the
area specifically obtained in the wall.
Take the internal wall-mounting part (4i) and the tools
necessary to connect the main supply to the stripped wires
supplied in the proper compartment.
Connect properly and safely the Live wires to the terminal
block identified as “N” and “L”.
Switching ON and OFF can be run by remote. To control the
product with recessed switch, it’s necessary, during
operation, that switches are always set on 1, as shown in
the picture (Y). To turn on the product through wall switch,
connect a bipolar switch in sequence to “L” and “N”, as
shown in the picture (a)
Product can be connected to the network home
automation by serializing the main supply to set switching
ON and OFF.

COMMUNICATION WITH SLAVE PRODUCTS
If you consider to install one or more products in sequence to the main unit or make the
connection in the future, refer to the pictures below to allow the communication between the
master unit and the products in sequence
.
It is recommended to use different cable colours to avoid to exchange the wiring connections.
Attention – It is necessary to respect the wiring connection between the signals S1-C1 and S2-C2
to avoid damages to the electronic device.
CONFIGURATION OF MASTER- SLAVE
In order to configure as MASTER Unit the selected product, proceed turning on it through the
main switch “0/1” and, once energized, if it hasn’t other products turned on and connected to C1
and C2.
Once the red light is turned out, press the button “AUTO”. If the red light gives the signal
corresponding to the “AUTO” mode, the product is correctly configured as MASTER.
Once the product is configured as MASTER unit, it is possible to start with the configuration of the SLAVE
1.
DO NOT SEND ANY REMOTE COMMAND TO SLAVE PRODUCTS.
Make sure the MASTER unit starts running before turning on the next unit (SLAVE) through the
“0/1” switch in order to give time to MASTER unit to configure the SLAVE products in the desired
sequence.
Turn on, through main switch, all the SLAVE units in sequence as explained below only after that
the previous unit has actually started running.
1) Master Unit
2) Slave 1 which runs in the opposite direction of the Master
3) Slave 2 which runs in the same direction of the Master
4) Slave 3 which runs in the opposite direction of the Master ….
ATTENTION
If the product is not correctly configured (MASTER or SLAVE), the RESET function can be used. In
this way the product can be brought back to original manufacturing conditions. This procedure is
explained in the command/control manual.
