System Conguration
Addressing
The communicating system components like room controllers, VAV controllers, remote I/O modules must have
assigned unique addresses identifying them at the bus communication.
The unique addresses of the room controllers and the RIO modules communicating on EXOLine are set for each device
by the manufacturer. They are composed of two numbers PLA(3 digits), ELA(3 digits). They can be found on the labels
and stickers attached to each device (refer also to user manuals of these devices).
The VAV controllers (Systemair Optima-BLC1MOD) communicating on Modbus have to be assigned before operation.
This is done by using the ZTH-GEN or ZTH-EU conguration tool from Belimo.
Connect the VAV controller to the power supply (wires 1,2).
Use the cable ZK1-GEN from Belimo connected to the conguration tool from one side and to the VAV controller
(bayonet socket on the controller front).
Scroll the menu on the tool (keys arrows up/down) down to point “MOD address” Change the address value (keys +/-),
conrm (key OK) – the address is set.
Disconnect tool from controller.

The addresses must be set from 1 to 30 for each controller connected to the same AIAS-Combox (no double
assignment of the same number to different controllers!). The addressing of the VAV controllers must be continuous,
e.g. „1, 2, 3, 4, 5“ etc. It must NOT contain unassigned numbers e.g. „1, , 3, , 5“ etc. The controllers connected to
different AIAS-Combox units can have the same addresses.
In the conguration menu these VAV-controllers with their addresses (MOD1 to MOD30) shall be assigned each to
one of the the program modules called Damper 1 to Damper 30 (see details in chapter „AIAS control/conguration
menu“ ). So the AIAS system can identify the connected VAV controllers by their unique Modbus addresses
