0 The setpoint for the motorized potentiometer is not saved and after ON is entered using p2240.
1 The setpoint for the motorized potentiometer is saved after OFF and after ON is entered using r2231.
0 Without initial rounding.
1 With initial rounding. The ramp-up/down time set is exceeded accordingly.
0 Non-volatile data save not activated
1 The setpoint for the motorized potentiometer is saved in a non-volatile fashion (for p2230.0 = 1)
Old value is kept
1 = OFF1, enable missing
For p2230.0 = 0, this setpoint is entered after ON.
If initial rounding-off is active (p2230.2 = 1), the selected ramp-up/down times are exceeded accordingly.
