The invention relates to an adjusting device (1) for a flow control valve (2), which adjusting device can determine a threshold of a hydraulic minimum opening position (Sv-hydraulisch-min) along a displacement path. The adjusting device (1) detects a flow based on a temperature change of the heat transfer medium in the consumer loop (3) and performs iterations from different opening positions. The determination process spans several external temperature control requirements, wherein missing iterations of the determination process, which are still pending after deactivation of the adjusting device (1) between the temperature control requirements, are continued upon reactivation of the adjusting device (1). L'invention concerne un dispositif de réglage (1) pour une vanne de régulation de débit (2) qui peut déterminer une valeur-seuil d'une position d'ouverture hydraulique minimale (Sv-hydraulisch-min) sur une voie de réglage. Le dispositif de réglage (1) détecte un débit sur la base d'une modification de température du caloporteur dans la boucle de consommation (3) et effectue des itérations de différentes positions d'ouverture. La détermination s'étend sur plusieurs exigences externes de thermorégulation, les itérations manquantes de la détermination, qui restent en suspens après la désactivation du dispositif de réglage (1) entre les exigences de thermorégulation, étant poursuivies lors de nouvelles activations du dispositif de réglage (1).
