CONFIGURATION OF CASCADED THERMAL UNITS
4.2 Configuration of the secondary system
Optimal use of the modules in cascade occurs by placing a hy-
draulic separator (available as an accessory) between the pri-
mary system (thermal modules in cascade for thermal genera-
tion) and the secondary system (users, such as heat distribution
systems, DHW production). This device allows a different flow
rate to be compensated between the primary and secondary
systems.

HYDRAULIC SEPARATOR
For the sake of simplicity, the hydraulic circuits downstream of
the separator can be identified as the secondary system.
The basic configuration of the secondary system takes place
using a system circulator (PI). This circulator, connected to the
modules in cascade, allows the transfer of the heat energy to a
user circuit to be controlled, for example, a direct zone for high
temperature heating of a room.

The secondary system can be configured using the following accessories:
− Secondary circuit sensor (SC)
This is required in order to manage the setpoint, and therefore the required temperature, downstream of the hydraulic
separator.
The secondary circuit sensor must be connected to the controller of the first "Depending" unit.
− Hot water tank sensor/thermostat (SB/TB)
This is required in order to manage the production of DHW in combination with a hot water tank circulator (PB).
The hot water tank sensor/thermostat is connected to the controller of the "Managing" unit.
