  Based on our photometric observations in 2015-2016 and archival photometric
data for the active red giant PZ Mon, we have found the main characteristics of
the stellar surface: the unspotted surface temperature Teff=4730K, the spot
temperature Tspot=3500K, and the relative spot area from 30 to 40%. The best
agreement with the observations has been achieved in our three-spot model
including a cool polar spot with a temperature of about 3500K as well as large
and small warm spots with a temperature of about 4500K. The stable polar spot
is responsible for the long-period brightness variations. Its presence is
confirmed by an analysis of the TiO 7054$~\AA$ molecular band. The
small-amplitude 34-day variability is attributable to the warm spots located on
the side of the secondary component, which determine the relatively stable
active longitude.
