The geothermal source comprises heat exchange probes installed in the geothermal medium. They allow for an exchange of heat between the geothermal medium and a heat-transport fluid passing through the probes. The method for controlling the installation involves: • defining a forecast trajectory (TP) for the temperature of the geothermal medium over the course of time; • evaluating, at least more or less in real time, the temperature of the geothermal medium; • making an adjustment to the thermal power exchanged between the geothermal medium and the heat-transport fluid which on leaving the geothermal probe has a temperature (TW), in the direction of making the temperature of the geothermal medium consistent with the forecast trajectory. The mean (TM) of the forecast trajectory (TP) is stable and preferably exhibits, with respect to the natural ground temperature (TN) a certain differential that gives rise to a non-zero annual thermal flux between the natural ground and the geothermal medium. Use to avoid the temperature drift of the geothermal medium and, in the preferred version, to increase the geothermal storage by the above-mentioned natural flux.
