4.12 User code
The access to some adjustment values can be restricted via a user code (customer).
1. Installer 0262 (Factory setting)
All menus and adjustment values are shown and all values can be altered.
If the installer user code is active, an E will be displayed next to the clock time.
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!

In order to restrict the access, enter 0000 in the User code menu item.
