The dominant frequency can be associated only with a radial mode and the second frequency is, most probably, a dipole mode. The other six frequencies have more ambiguous identifications. The photometric mode identification provided also some constraints on the atmospheric metallicity [m/H]$\\approx$+0.5 and microturbulent velocity $\\xi_t\\approx 4~\\kms$.\\\\ For models reproducing the dominant frequency, we show that only the fundamental mode is possible and the first overtone is excluded.
