Differences between the AK-SM 8xx and the AK-SM 8xxA

Files in the AK-SM 8xxA

The EDx files are used to describe the controllers that can communicate with the AK-SM 8xxA. They contain information about all the parameters for the particular controller, their limitations, where they are used, whether or not they are writeable or read only etc.

It is also in the EDx files that you can find the description for which parameters should be used for the different functions that the AK-SM 8xxA has. For instance, when you enable a Defrost schedule, and add a controller to this, it is the EDx files that contain the correct tagging for which parameter should be activated when the schedule turns on.

For the AK-SM 8xxA, the files were managed individually and a device.ls3 file contains a list of all the supported controllers. This has changed now in the AK-SM 8xxA, where there is a package (.epk) of controllers that are validated by Danfoss and includes all the details that are required for the System Manager in order to use the particular controller.

It is possible to update the epk package from a computer with internet connection or by downloading the latest epk. package from our website and updating with the local stored file option:
