<p>A device for controlling the operation of a refrigeration appliance such as a domestic refrigerator, a freezer or the like, consisting of a circuit (2) comprising generator means (3, 4, 5, 6) for generating reference signals (VA) to be compared with analogous signals (VE) originating from sensor means (21), said generator means having adjustable characteristics and being activated sequentially by sequencer means (16) which also control the feed of data (Vc) deriving from said comparisons into memory means (26, 27, 28); the sequencer means (16) are connected to means (35) for controlling the refrigeration appliance, which read the data in the memory means (26, 27, 28) at the end of each sequence of comparison between the reference signals (VA) and the signal (VE) from the sensors (21), and on the basis of this reading operate on the usual components (42, 43, 44) of the refrigeration appliance which generate and control its cold. <IMAGE></p> |
