We identify two temperature regimes (a) $T_{Kondo}<T\\le T^{wire}=\\hbar v_F/k_Bd$ ($d$ is the length of the short wire) and (b) $T<T_{Kondo}\\ll T^{wire}$. In the first regime the effective (renormalized) electron-electron interaction is smaller than the tunneling matrix element. This is the situation at finite temperature $T$ where the single particle spectrum of the wire is characterized by a multilevel \"quantum dot\" system with magnetic quantum number S=0 which is higher in energy than the SU(2) spin doublet $S=\\pm1/2$.
