﻿A daytime colour temperature sequence is of the same priority as the normal control of the brightness and colour temperature of a group or single device by the corresponding communication objects. A scene recall also is of the same priority. The functions mentioned above override a daytime colour temperature sequence in progress with regard to the colour temperature and brightness.

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

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

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