An exchange-bias (EB) effect observed in single crystal ErFeO3 compensated ferrimagnet, exhibiting the EB field HEB increasing and diverging upon approaching compensation temperature Tcomp=45K, and changing sign with crossing Tcomp, is reported. The EB sign may be changed to the opposite one by varying the field-cooling protocol, depending on whether Tcomp is crossed with decreasing or increasing temperature. Namely, a different EB sign with the same |HEB| and coercive field HC values is obtained approaching a given T with increasing and decreasing temperature and the HEB(T) dependence completed in one way is a mirror image of that completed in another way.
