ELECTRICAL CONNECTIONS
Disconnect the electrical supply before any operations and ensure that the DXA Unit
cannot be started accidentally.
Only cables provided by Aereco must be used to carry on the DXA Unit installation. If using
different cables, Aereco won’t be able to guarantee the good functioning of the appliance.
The installation must be carried out by a professional
in compliance with applicable
regulations in force in the country of installation. Each product or component used in the
installation must also comply with standards in force in the country.

Note:
RJ12 and RJ45 cables provide both supply and connections. The DX Hub allows also 5 RJ12
connections where sensors (or user’s interface) can be connected instead of connecting sensors to
the DXA Unit itself. However, the maximal RJ12 cable length between the DX Hub and the sensors
must not exceed the length calculated thanks to the equation below :

RJ12 maximal length:
RJ45 maximal length:
DXA Unit to the interface 10 m max.
DXA Unit to the exhaust compensation valve
10 m max.
DXA Unit to sensors
30 m max.
Do not connect RJ45 cables to an Ethernet or a phone network. Only external devices
provided by Aereco must be connected to RJ plugging.
The DXA Unit is not designed to be connected to smart home system; settings and data
display are realised only through the Aereco touch screen interface.
