The effect of annealing at room temperature on the excess conductivity of oxygen deficient HoBa_2Cu_{3}O_{7 - δ} single crystal is studied. It is shown that there is substantial extension of the interval of linear dependence ρ_{ab} (T) and narrowing of the temperature area of the pseudo-gap regime as a result of annealing. The excess conductivity satisfies the exponential temperature dependence in a wide temperature interval. The temperature dependence of the pseudogap is satisfactorily described by the BCS-BEC theoretical model.
