Cables
The cables used in the network must conform to RS-485
­Standard with twisted pair conductors. The cables must be
shielded. The network should be built as a bus line with common
conductors connected. The type of cable must conform to
­EIA-485 Standard. Swegon has suitable cables in stock.
Usable types of cables:
1. LINK Wa network cable, Modbus

2. LiYcY from Nexans
3. Belden 9842
Network structure
The system is divided up into two levels: the zone loop
and room loops. The zone loop is connected between the
Super WISE and all the zone/router products. There can be
a maximum of 10 zones with up to 8 zone dampers in each
zone. Up to 60 room controllers (nodes) can be connected
within each zone. The so-called room loop can be divided
up into several different loops that can be connected to
optional zone dampers/routers within the zone. The zone
product Modbus ID is the factor that determines to which
zone it belongs, not its physical location inside the building.
To ensure the correct operation of the room products, each
zone has to have a Modbus ID series that is the same for all
the zones. Therefore it is important that the room loops are
always connected to the “correct zone”.

RS485 Modbus standard prescribes colour code brown/yellow/

cable, always connect ’+/-’ within one single pair.

Network Structure with BACnet
If you intend to connect the Super WISE up to BACnet,
strict rules apply to how you install and connect the network cable. BACnet requires an EDE file which you can
create directly in the Super WISE after its installation. The
EDE file must not be created until all the controllers in the
system are connected and have been detected by the Super
WISE. If the EDE file is created beforehand, strict rules will
apply to installing the network; it will then have to follow
the EDE file structure without the slightest deviation.

WISE – network
Network section 1. Super WISE -> Zone products, blue loop.
The network cable should be run continuously (bus line) from Super WISE (1) down to the last zone damper or the Router
(3). The total length must not exceed 600 metres. Super WISE is the master in the Modbus network and has a built-in termination. It must therefore be placed at one end of the loop.

Swegon reserves the right to alter specifications.
Position 1
Passive termination for Modbus Slave is used if the
product is placed first or last on the loop.
Position 2
Termination for Modbus Master, with internal
pull-up resistor to ensure a proper 0 level, is
permissible only on the first or last unit in the
network.
Position 3
Unterminated for Modbus Slave, used if the products are mounted in the middle of the loop.

WISE – network
Network section 2. Zone -> room controllers, red loop.
In this example, each floor of the building has a Modbus loop of its own that should be terminated in each end. CONTROL
Zone (1) or Super WISE Router (2) acts as a Modbus Master and is as standard terminated on delivery. The total network
cable in each zone must not exceed 600 m.
