The ZZ Ceti star KUV was observed over a whole season at the mountain station of Konkoly Observatory. A rigorous frequency analysis revealed 6 certain periods between 619 and 1250 seconds, with no shorter period modes present. We use the observed periods, published effective temperature and surface gravity, along with the model grid code of Bischoff‐Kim, Montgomery and Winget  to perform a seismological analysis. We find acceptable model fits with masses between 0.60 and The hydrogen layer mass of the acceptable models are almost always between and In addition to our seismological results, we also show our analysis of individual light curve segments. Considering the non‐sinusoidal shape of the light curve and the Fourier spectra of segments showing large amplitude variations, the importance of non‐linear effects in the pulsation is clearly seen.
