Cannot remove ziggbee device from Tahoma Din Rail

Hello,

I try to redo the pairing of my Danfoss Icon floor heating systems with my Tahoma Din Rail. Therefore, I need to undo the previous (zigbee) connections. However, every time I try to remove them, an error returns and the devices persist.

Can you help me by removing them on the server side? The PIN code of the box is 1001-8975-8003 and the devices are Zigbee 44833/1, 44833/2, 44833/3, 44833/4.

Thank you.

Benno Haarman
