﻿A forced position influences only the brightness control of a group or single device. The colour temperature or colour - provided that the groups and single devices have this range of functions - always remains unchanged in a forced position. This parameter defines the behaviour to be carried out when a forced position is activated via the communication object and the group or the single device is to be forcibly switched on.

*Preset*: The DALI operating devices set themselves to the brightness configured in the "Brightness value" parameter in the event of a restraint.

*No reaction*: The bus operation is locked but the operating devices show no response and remain in the most recently set brightness state.

*Memory value (brightness before last switch-off)*: The brightness value is set that was active before the last switch-off and stored internally in the device. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory value is predefined to "100%". This value is optionally limited by the maximum brightness.
