what is the usage of "residualControl" in rhoPimpleFoam?

when residuals is assigned before what does "residualControl" do?

Code:

"(U|e|h|R|k|epsilon|omega)"
    {
        solver          PBiCG;
        preconditioner  DILU;
        tolerance       1e-11;
        relTol          0;
        maxIter 25000;
    }

    "(U|h|R|k|epsilon|omega)Final"
    {
        $U;
        relTol          0;
    }
}

Code:

PIMPLE
{
    momentumPredictor yes;
    nOuterCorrectors 3;
    nCorrectors     3;
    nNonOrthogonalCorrectors 0;
    rhoMin          rhoMin [ 1 -3 0 0 0 ] 0.2;
    rhoMax          rhoMax [ 1 -3 0 0 0 ] 9;

residualControl
    {
        "(U|k|omega)"
        {
            relTol          0;
            tolerance       0.000000001;
        }
    }
