Local Area Network (LAN)
The compressors to be controlled must be connected with each other in a Local Area Network (LAN) using
CAN (Controller Area Network) technology.
The controller with the integrated ECOi function serves as master regulator for the compressors. The
regulators of the other compressors act as slave regulators.
Relay regulated compressors can be connected to the network by means of a conversion box and/or a
communication module between regulator and network (see the next chapters for details).
Select the compressor regulator which will serve as the master regulator for all compressors in the LAN
and label this compressor as Master Compressor 1.
Select the compressor regulators which will serve as slave regulators. (Label the compressors Compressor
2, 3 and 4, 5, 6 respectively).
10.2.2 Installation instructions
Important remark
Always stop each compressor and switch off the voltage before making any connection!
Connecting compressors equipped with 4th generation controllers
All electronic control modules of the fourth generation can directly be connected with each other using the
LAN port as shown in below figure:
