In this paper, we apply the finite element and backward Euler scheme for the space and time approximation of a constrained optimal control problem governed by a parabolic integro-differential equation on multi-meshes. We firstly establish the weak formulations for the control problem and then derive equivalent a posteriori error estimators with lower and upper bounds for both the state and the control approximation. These indicators are then used in our adaptive multi-meshes finite element schemes. Finally some numerical tests are presented to verify the effectiveness of the indicators.
