Abstract
Some inconsistencies between spectrographic and photoelectric elements of the double-spectrum eclipsing binary ZZ Boo revealed that a set of spectrographic observations should be interchanged. With the newly deduced elements the star appears to be a normal detached system on the upper border of the main sequence. Both components agree well with an isochrone of age 1 billion yr and chemical composition Y = 0.30, Z = 0.004.
