During normal operation, the coupler filters telegrams according to its filter table and its position within the KNX topology.

During commissioning or diagnostics, it may be useful for the coupler to temporarily forward all group telegrams and/or physically addressed telegrams.

This forwarding mode can be activated using the Pass IA and Pass GA buttons.

The Forwarding Duration parameter defines how long the manual forwarding remains active before the coupler automatically returns to normal filtering.

If the corresponding button is pressed again during this period, manual forwarding is terminated immediately.
