Hi Jukka, thank you for the fast response!
Yes, it is possible to add the NoDataValue in the request, when you will set up this manually. Perhaps it is a quick solution to do this and send the noValue as parameter to the remote service as long the GDAL WCS 1.1.x request doesn't work. Thanks for the idea!
