5. Summary

Below we summarize our conclusions:

1) BPM 24754 is the 28th ZZ Ceti star with a period of  min and amplitude between 0.007 and 0.025 mag. It has the second longest period;

2) It does not fit the period-amplitude relation;

3) The amplitude spectrum indicates a multiperiodic light curve;

4) We need to gather extra single site data to better interprete its amplitude spectrum;

5) The fundamental parameters are:  K, , and ;

6) The is hotter than the blue edge of the observed ZZ Ceti instability strip;

7) We need a UV spectrum to obtain a consistent solution for and .
