Assume that we goal to operate internally communicating 3 aiM condensing boilers as cascade.
The boiler adressing must be done correctly as a prerequisite. In order to communication take
place, OCI 345.06 module should be used. This module is an internal node for the cascade
communication network.
Following the hardware connections, in order to make the adressing by the software, an HMI (AVS

one by one. The authorized services should own an HMI module in their inventory plus the
connection cable.
In this adjusting sequence, it is different that the use of the X50 terminal and the AVS75.390 or
AGU (expansion) module are in different means. The AGU module should be reconnected to the
X50 terminal after boiler/cascade adressing is done. Please also refer to Section 4.4.2
module.
