System Diagram - Grundfos CIU 300 Functional Profile And User Manual

2.4 System diagram

The system diagram gives an overview of how to connect the
CIM/CIU 300 to the Grundfos booster system that is to be
connected to a BACnet MS/TP network.
The CIU 300 solution is a box with a power supply module and
a CIM 300 BACnet module. It can either be mounted on a DIN rail
or on a wall.
It is used in conjunction with Grundfos Hydro MPC, Control MPC
and Multi-E.
The CU 351 must have an external GENIbus module
installed to communicate with the CIU 300 BACnet
