Code
The access to some adjustment values can be restricted via a user code (custom-
er).
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!
Î In order to restrict the access, enter 0000 in the menu item CODE.
The display changes to the status level. The short menu shown will then be available
in the adjustment level. The short menu suits the selected system.
Î In order to authorise access to the installer level, enter 0262 in the menu
item CODE.
