INSTALLATION OF SYSTEM INTERFACE
Positioning
The system interface recognizes the temperature of the environment,
so this factor must be taken in consideration during the choice of the
positioning of the same.
We recommend to place the remote control away from sources of
heat (radiators, direct exposure to sunlight, fireplaces etc.) as well as
positioning near drafts or openings to the outside which may affect
the operation of system interface, should be avoided.
You are also required to place the interface at least 1.5 m from the
floor.
WARNING:
USE ONLY THE PROVIDED SYSTEM INTERFACE.
WARNING
User interface installation has to be made by a qualified techni-
cian. Before installing, disconnect power supply before instal-
ling the remote control.
Wall installation
The Sensys system interface must be fitted to the wall before the BUS
line is connected.
- connect the pair of wires to the connector (fig. 1);
- open up the holes required for fixing;
- fix the base of the device to the box on the wall using the screws
supplied in the kit (fig. 2);
- position the system interface on the base, pushing it gently
downwards (fig. 3).
Connection to the installation
The sending, receiving, and decoding operations are performed by a
BUS signal protocol, which ensures the interaction between the sys-
tem and the interface.
Connect the wires to the terminal block included in the electrical panel
of the internal unit of the system.
NOTE: To avoid interference problems when connecting the
system interface and internal unit, use a shielded cable or
twisted pair cable.
