The C112 locking code can only be adjusted by the manufacturer.

From the basic display, you may skip the user level, to reach the parameter level.

Press and hold, for 3 seconds, and release.

The actual value display, (0) shows the current parameter value.

The setpoint display, (AL)

shows the parameter item you are adjusting.
