Abstract
The control system includes: a memory for memorizing a table of correspondence between inputs which comprise, on the one hand, sets of parameters and, on the other hand, operational adjustments of the working parts of the installation; an installation interface for instigating such adjustments; and a data unit having touch pads or other manual setting elements operated by the user so as to define a set of desired (or running) parameters. The data unit also has manual programming elements, and the memory includes individual zones for storing a set of parameters, each of these zones being associated with one of the manual programming elements, so that actuation of one of the latter stores the set of running parameters in the associated programming zone as a set of programmed parameters. The control system also includes selection means for designating a set of programmed parameters in accordance with a predefined criterion, in such a way that the installation interface can then instigate the corresponding adjustments.
