﻿A daytime colour sequence is of the same priority as the normal control of the brightness and colour of a group or single device by the corresponding communication objects. An automatic colour wheel sequence, an automatic brightness sequence or a scene recall also has the same priority. The above functions override a daytime colour sequence in progress in terms of colour and brightness.

In the event of an override, a daytime colour sequence in progress can be stopped automatically, or alternatively continue to run in the background. The behaviour is defined by this parameter.

*CTM continues to operate*: An ongoing daytime colour sequence can be overridden at any time by other functions of the gateway. However, the daytime colour sequence continues to run, whereby the values stored in the CTM matrix continue to be called up continuously every minute, depending on the time. In this case, the last received or given commands for the colour or brightness of other functions (e.g. scene recall) are replaced by the CTM values again after one minute at the latest. For daytime colour gradients with brightness adjustment, the brightness values defined in the CTM matrix are tracked. The gateway then continues to process the interpolated brightness values every minute and, if necessary, switches on any operating devices that have been switched off. With daytime colour sequences without brightness adjustment, the colour is internally tracked by the CTM matrix even if groups or single devices are switched off. If a group or single device is switched on, the gateway sets the tracked colour so that DALI operating devices subsequently switched on display the correct values of the daytime colour sequence.

*CTM is terminated*: If a daytime colour sequence is automatically stopped by an override, the gateway immediately stops processing the assigned CTM matrix.
