A/c problem


The VCM with IDS list me the trouble code B2477, DATC isn´t configured. If i try to config it with IDS, i have to insert a code and the note, that i can get it on a dealer webside, but i don´t have access here from Germany. How can i find out the right code?
I have to configure it, because in the morning, the system blow only cld air, till i select every switch one by one, than i get warm air.
Thank you so much for help
