Abstract
A control device, for an air-conditioning plant having a central heater or cooler and several units 1 in different rooms, which takes as a reference the room in which, from time to time, the ambient temperature differs the most from a nominal pre-chosen value unique to that room on account of the heat load at that particular moment, and varies the power output of the heater or cooler as a predetermined function of that temperature difference. <IMAGE>
