In the locked view the controller provides all display functions. No setting functions are available.
The setpoints are shaded (light grey) in normal display. Changing them by direct entry in the fixed value
operating mode is not possible. The functional icons for setpoint entry and program start in the footer are

After turning on the unit, user log-in is required to operate the controller (chap. 12.2).
Operation without user log-in / without password-protection
If the password function has been deactivated, after turning on the unit without user log-in there are those
controller functions available, which correspond to the highest authorization level without a password
protection. There is no lock icon in the header.
