Engineering Data
 Connection line group for IDU and ODU / MS communication
Used to connect IDU and ODU communication and transfer the control signals of the IDU and ODU. Please use the wire with
a shield layer and ensure that the shield layer is grounded. For instructions on how to connect the ODU or MS, please see the
corresponding manual.

 Group control connection method/KNX gateway connection method
 The hydraulic module can provide the function of group control so that one module can control multiple units. In the
entire system, only one master wired controller can be deployed to control units. Each unit can connect one slave
wired controller for data query.
 Up to 10 units can be controlled.
