Installation and connection
3.2 Aetwork
All components of the control communicate with each other via an RS 485
bus system. Careful planning of the network prior to installation saves you
elaborate and time-consuming adjustment work.

Bus topology
Please observe the following items regarding the network structure:
A maximum of one control panel, 1200 actuators, 3 weather stations and
2 sensors for inside temperature/humidity may be used in one system.
When using 100 actuators or more, one hub is required per 100 devices.
One hub is required after every 1200 m of line length.
3.2.1 Aetwork cables
Use only high-grade twisted-pair network cables with a characteristic wave
impedance of 120 Ω.
We recommend using:
JY(St)Y 2x2x0.8 mm ø or JY(St)Y 4x2x0.8 mm ø
YCYM 2x2x0.8 mm ø or YCYM 4x2x0.8 mm ø (Siemens)
Unitronic bus line 2x2x0.8 mm ø or 4x2x0.8 mm ø (LAPP)
Cables resistant to UV rays must be used for outdoor installation
(e.g. to connect the weather station). We recommend using:
8x AWG26 C UL black
A-2Y(L)2Y...ST III BD 2x2x0.8 mm or 4x2x0.8 mm
