Wind Vector datablock operates on pure dynamic data, regardless of what's entered in the Air Data Calculator. The Air Data Calculator items will get populated via the air data source - note the green-colored parameters as the air data sourced items.
In the examples below, I set the HDG to 280 in the Air Data Calculator resulting in a non-calm Wind Vector. The Wind Vector datablock never changed. When I set it back to the sourced data, the Wind Vector shows calm.
