Abstract

L'invention porte sur un système central de régulation et son mode de fonctionnement qui limite les signaux de commande reçus par les unités intérieures et règle lesdites unités selon des valeurs de consigne programmées transmises par une unité centrale de régulation. Selon l'invention, les unités intérieures peuvent être commandées individuellement en limitant les entrées de signaux extérieurs agissant sur les unités intérieures et en disposant les unités intérieures pour qu'elles soient commandées par les signaux de l'unité centrale. En outre, comme les unités intérieures peuvent être commandées individuellement, on prévient la consommation inutile de courant, on améliore l'efficacité de l'unité centrale et on renforce la fonction de programmation.
