ABSTRACT:
The present invention relates to a method and to apparatus for regulating a heating installation in a premises comprising a plurality of heating generators. The apparatus comprises temperature probes (10, 20, 140) which are sensitive to the outside temperature, to the inside temperature, and to the departure temperature of the heating fluid leaving the heating generators. The apparatus further includes means (50, 60, 70, 80 and 100) for determining a reference temperature on the basis of a set temperature (Tc) as indicated by a setting unit (30). A proportional-integral regulator (120), sensitive to the difference between the reference temperature and the departure temperature of the fluid, generates a signal which is applied to threshold detectors which detect the passage of said signal through successive predetermined thresholds, thereby generating successive signals for bringing into service the corresponding heating generator.
