1. Installer 0262 (Factory setting)
All menus and adjustment values are shown and all values can be altered.
2. Customer 0000
The installer level is not shown, adjustment values can be changed partly.
For safety reasons, the user code should generally be set to the customer code
before the controller is handed to the customer!
