﻿At this point, you can define when the gateway updates the feedback value for the status of an invalid colour temperature. The object value updated last by the gateway is then actively signalled to the KNX, provided the "Transmit" flag is set on the communication object.

*after each update of feedback value*: The gateway updates the feedback value in the object as soon as a new telegram is received to specify a colour temperature value. The default colour temperature value does not necessarily have to change. Consequently, in the event of, for example, cyclical telegrams to the input objects, the corresponding status telegrams are also generated.

*only if the feedback value changes*: The gateway updates the status of an invalid colour temperature only if the telegram value also changes. If the telegram value does not change (e.g. in the case of cyclical telegrams to the input objects with the same telegram value), the status then remains unchanged. Consequently, no telegram with the same content is output repeatedly either.
