  We use original spectra and available photometric data to recover parameters
of the stellar atmosphere of PZ Mon, formerly referred as an active red dwarf.
The derived effective temperature Teff=4700K and gravity lgg=2.8 suggest that
PZ Mon is a K2III giant. Stellar atmosphere parameters (Teff and lgg) alongside
with the evolutionary tracks are used to estimate the stellar mass of ~1.5Mo
and the radius of ~7.7Ro. The angular radius derived by the infrared flux
method when combined with the linear radius suggests the distance of 250+/-70
pc, a factor 2.5 smaller than that suggested by the Hipparcos parallax. The red
giant status of PZ Mon is confirmed by the carbon and nitrogen abundance. The
spectrum reveals pronounced HeI 5876 A absorption and Halpha emission
indicating the robust chromosphere. The IUE spectrum is found to contain
transition layer emission line of CIV 1550 A. The CIV and X-ray luminosities
turn out typical of RS CVn stars. The extended set of available photometric
data confirms the period of 34.14 days presumably related to the stellar
rotation. We found variations of the radial velocity with the amplitude of ~8
kms which could be caused by the orbital motion.
