It was selected from the $Kepler$-INT Survey (KIS) on the basis of its colours and its variable nature was confirmed using ground-based time-series photometry. An atmosphere model fit to an intermediate-resolution spectrum of KIC11911480 places this DA white dwarf close to the blue edge of the empirical boundaries of the ZZ Ceti instability strip: $T_\\mathrm{eff} = 12\\,160 \\pm 250$ K and $\\log{g} = 7.94 \\pm 0.10 $.
