Abstract. We will look at C$^*$--dynamical systems with the translations of $\BR^d$
as dynamical group and will define KMS--functionals for $\beta$ taking
values in $\BC^d$. The properties of such functionals will be investigated.
In particular if a KMS--functional exists for a complex $\beta$ then
it will be shown that there exists a KMS--state for the real part of $\beta$.
If the system is a theory of local observables then it will be shown that
locality condition implies that there do not exist $\beta$--KMS--functionals
such that $\beta$ is spacelike or has a spacelike real part.
