ELECTRICAL CONNECTIONS
Disconnect the electrical supply before any operations and ensure that the unit cannot be
started accidentally.
Only cables provided by Aereco must be used to carry on the DXR 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.

Defrosting control: 0.5 mm²
Input pump alarm: 0.5 mm²
Supply (230 V): 1.5 mm².
Note:
The DX Hub allows also 5 RJ12 connections where sensors (or user’s interface) can be
connected instead of connecting sensors to the DXR 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 :
·L
SH
= 30 - (n
SH
* L

)
·With L
SH
: RJ12 cable length between the sensors and the DX Hub
·n

: number of sensors directly connected on the DX Hub
·L
UH
: RJ45 cable length between the DXR Unit and the DX Hub.
Note:
RJ12 and RJ45 cables provide both supply and connections. RJ12 cables can be connected
anywhere (DXR Unit or/and DX Hub), as long as the maximal length of the cable is respected.
RJ12 maximal length:
RJ45 maximal length:
DXR Unit to the interface 10 m max.
DXR Unit to the exhaust compensation valve 10 m max.
DXR Unit or DX Hub to sensors 30 m max. DXR Unit to DX Hub 10 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 DXR is not designed to be connected to smart home system; settings and data
display are realised only through the Aereco touch screen interface specific interfaces
(touch screen or basic one).
