CASCADE FUNCTIONALITY
The term cascade is intended to indicate a group of water he-
aters that work together, within which only one Master and se-
veral slaves are identified.
The Master has the task of managing the operation of the units
connected to it.
The electronics of the unit, in fact, allows the unit to be configu-
red both as Master and as Slave.
While managing the cascade, the MASTER can manage three
different levels of operation, depending on the user's request:
1. minimum level of functioning
2. medium level of functioning
3. maximum operating level
Under normal operating conditions, the MASTER has full con-
trol of all Slaves.

•

•
modify some parameters of all the Slaves according to its
values
•

SLAVE

sible to change the system status, such as set-
