<p>Ventilator comprising a fan (81); an electromotor (5) having at least one excitation winding (6, 7) and a rotor (8) coupled to the fan (81); controllable excitation means (13) coupled to the at least one excitation winding (6, 7) and provided with connection terminals (3) for connection to a power supply (4); means (14) for detecting the rotary speed of the fan (81); a digital processing circuit provided with a processor (1) and at least one memory (17, 18) for storing control and processing software and control parameters; and means (24), coupled to the processor (1), for exchanging control data via a communication link (27) between the processor (1) and a control station (22). The communication means (24) may furthermore be designed for feeding a signal, originating from separate means (23) for setting the fan rotary speed, to the processor (1) via the communication link (27). The ventilator may furthermore be provided with a unique address stored in the memory means (17, 18). <IMAGE></p> |
