GRUNDFOS COMMUNICATION INTERFACES
The CIM/CIU 100 and CIU 110 is a standard interface for data transmission between a LON network and
a Grundfos pump or controller. It makes data exchange possible between Grundfos pumping systems
and a building management system.
The communication interface is fully compliant with the standard LONmark functional profile 8120
“Pump Controller”, ensuring interoperability with other LON devices.
The communication interfaces have been certified as conforming to LonMark Application Layer
interoperability guidelines 3.4.
The interface module can be installed as an internal add-on or as a wall-mounted unit where internal
connection is not supported. The wall-mounted unit is equipped with a 24-240 VAC/VDC power supply.
In addition to LON, interface modules are also available for GENIbus, BACnet, Modbus, Profibus, GSM
and other systems.
Communication interface for LON
– easy integration in building automation
CIM 100 add-on module
The CIM 100 is an add-on communication module
installed internally in 11-22 kW Grundfos E-pumps.
CIU 100 / CIU 110 wall-mounted/DIN-rail unit
The CIU 100 and CIU 110 with internal power supply
are for Grundfos products that do not support the
add-on module.
