Aims. The purpose of this corrigendum is to point out that a handful of models in the original paper were computed with faulty initial structures.
Methods. Using exactly the same modelling methods we have recomputed the faulty models with new initial structures.
Results. The new results slightly changes some of the trends in the wind properties with stellar parameters, but the overall effects are small. The conclusions are not affected

While recomputing parts of the grid of wind models (Mattsson et al. 2010) in order to obtain extended time sequences for modeling of spectral variation (Eriksson et al., in prep.) we discovered that a few models had faulty starting structures. A closer analysis revealed there were in total nine models that needed revision. We recomputed the faulty hydrostatic start models as well as the wind models and below we present a table (Table 1) with the resultant wind properties. Qualitatively, these
Input parameters (Δvp, M ⋆ , log (L ⋆ ), L ⋆ , Teff, log(C-O), P) and the resulting average mass loss rate, average wind speed and the mean degree of dust condensation at the outer boundary.
new numbers have no major impact on the overall result, although they would slightly affect the appearance of Figs. 6 and 7. The conclusions are not affected.
