Un appareil d'évacuation d'air (4; 4a, 4b) sert à évacuer dans un espace extérieur (1)l'air contenu dans un espace intérieur (2). L'appareil comprend une unité de commande (7; 7c, 7d; 1.0) associée à un capteur d'humidité (5a; 1.41, 1.42) qui détecte l'humidité de l'espace intérieur comme valeur de mesure. L'unité de commande comprend une unité de traitement (71a à 71d; 1.2) qui produit un signal de commande à partir de la valeur de mesure et un organe de réglage (72c, 72d; 1.11; 411) qui reçoit le signal de commande afin de modifier la quantité d'air évacué en fonction du signal de commande. L'unité de commande (7; 7c, 7d; 10.1; 40) est conçue comme une commande programmable par un microprocesseur ou par une mémoire et est associée à au moins un capteur additionnel de signaux (5b, 6; 1.611, 1.612, 1.613) qui détecte automatiquement une autre valeur de mesure et/ou une valeur de commande (réglage du dispositif) temporelle ou prédéterminée par l'utilisateur ou les utilisateurs de l'espace intérieur. L'unité de commande (7; 7c, 7d; 1.0) comprend une unité de traitement logique (1.81) qui produit le signal de commande à partir au moins de la valeur de mesure et de la valeur de commande, de sorte que lorsque l'humidité dans l'espace intérieur dépasse une valeur prédéterminée, un signal de commande est émis pour actionner, au moins de façon intermittente, le dispositif d'évacuation d'air (4; 4a, 4b) afin de faire descendre l'humidité dans l'espace intérieur au-dessous de la valeur prédéterminée. Sinon, le signal de commande produit à partir de combinaisons données des valeurs réelles et des valeurs de commande.
