﻿A relative colour temperature dimming telegram can also switch on a group or single device in the "OFF" state, with the behaviour set by this parameter.

*Switch-on*: The group or single device in the "OFF" state is switched on to the configured switch-on brightness by a relative dimming telegram of the colour temperature. The colour temperature is set to the configured switch-on colour temperature. Based on this colour temperature state, the colour temperature to be dimmed is dimmed. The relative dimming telegram that leads to switching on, specifies the dimming direction and dimming increment. The dimming process stops after reaching the specified colour temperature.

*No reaction*: The group or the single device in the "OFF" state is not switched on by the relative dimming telegram. The group or single device remains switched off. The next time the device is switched on, the colour temperature value dimmed last is tracked only if the "Switch-on colour temperature" parameter is configured to the "track" setting.
