<p>The error signal of a primary regulation circuit 10, 18, 20, 22, 24, 30, 32, 42, 44, 46, 50, 28, 52, 16 and 14 is infed as a control signal or magnitude to an air quantity auxiliary regulation circuit 24, 30, 32, 42, 44, 46, 50, 28 and 26. The quantity of supply air which is infed to the room or area which is to be ventilated or climatized, is proportionally influenced as a function of the regulation magnitude of the primary regulation circuit. A lower threshold and an upper threshold are adjusted for the infed quantity of air. In order that the proportional band, related to the room temperature, shall remain independent of at least the adjustment of the upper selected threshold or threshold value, the slope of the regulation characteristic of the proportional band is altered at least during adjustment of the upper threshold. By virtue of such arrangement, computation and post- setting of the proportional band is not altered at least during adjustment of the upper threshold. The primary circuit compares at 10 the actual room temperature, measured at 16, with a desired value set at 11. The auxiliary circuit compares at 24 the actual air flow or velocity, measured at 28, with the temperature error. The only corrector is a flap or valve 48. <IMAGE></p> |
