ABSTRACT:
With a process for setting the temperature difference between cut-in temperature and cut-out temperature of a heating unit or, in particular, of a refrigerating unit in the region of a set value, to be maintained, of the temperature of a medium or of a room, for automatic adaptation of the temperature difference between cut-in temperature and cut-out temperature to changing loads, the temperature which, starting from the set value, is reached by the unit below or above the set value after expiry of a preselected unit of time in each case being established repeatedly, whereupon these established temperatures are compared and that temperature which coincides with several previously measured temperatures is used for setting the temperature difference between cut-in temperature and cut-out temperature.
