Adressing and Communicating the Boilers
In cascade operation, all the boiler adresses should be correctly defined. In other case, you can
notice the error number 82: LPB Adress Collision. For doing the adressing, enter the LPB section
in every slave. In addition, please also check that the parameter 6600 at
the master should be equal to 1. Master boiler is the one with the outside temperature sensor
and cascade sensor connections.

All the aiM (S) slave boilers has an OCI
cascade module as factory mounted.
Thus, in case of your slave boiler orders
or purchases, there is no need for an
additional OCI module order / purchase.
This situation is not true for the master
boilers.
Emerging needs for expanding your
central heating system by adding new
slave boilers will arise the need that only
1 piece of OCI module (for the master
boiler) should be purchased.
2, 3, 4, 5... in order.
