The aim of this paper is to study the problem of constrained controllability for distributed parabolic linear system evolving in spatial domain $\Omega$ using the Reverse Hilbert Uniqueness Method (RHUM approach) introduced by Lions in 1988. It consists in finding the control $u$ that steers the system from an initial state $y_{_{0}}$ to a state between two prescribed functions. We give some definitions and properties concerning this concept and then we resolve the problem that relays on computing a control with minimum cost in the case of $\omega = \Omega$ and in the regional case where $\omega$ is a part of $\Omega$.
