1.5.3 CSNET MANAGER
CSNET Manager: CSNET Manager is connected to another CSNET Manager that it is connected to the H-LINK installation through
a HC-A64NET or PSC-A160WEB1. The maximum number of indoor units controlled by CSNET Manager is 1280 in case of having 8
connected PSC-A160WEB1 devices. Furthermore, two CSNET Managers can be interconnected, allowing each of them to monitor
and control the H-LINK installation connected to the other one.
One CSNET Manager can control up to 8 CSNET Managers, but the total quantity of controlled indoor units can never exceed the
maximum quantity of 1280 indoor units.

HC-A64NET can be connected only to one CSNET Manager.

(*3): Each CSNET Manager can only share with other CSNET Manager devices the control of those indoor units that are connected directly to it
through HC-A64NET or CSNET WEB interfaces.
