  We investigate the phase structure of pure SU(2) LGT at finite temperature in
the mixed fundamental and adjoint representation modified with a Z2 monopole
chemical potential. The decoupling of the finite temperature phase transition
from unphysical zero temperature bulk phase transitions is analyzed with
special emphasis on the continuum limit. The possible relation of the adjoint
Polyakov loop to an order parameter for the finite temperature phase transition
and to the topological structure of the theory is discussed.
