Help codes list
The last appeared four errors are stored in a list by the software. If an
error appears, which is already in the list, he will not be listed again.

It is possible that an error is only displayed for a short time, but after the
acknowledgement it will disappear. In this case, it's recommended to
switch off the control unit and switch it on again (reset by restarting).
