The invention relates to a method for regulating a circuit for the recirculation of hot sanitary water, and to an electronic control circuit. The invention consists of an electronic control circuit, a water temperature sensor, a flow switch and a timer, characterised in that a signal from the flow switch of the water circuit is acquired when a hot water tap is opened, and if the temperature of the point-of-use of hot water is equivalent to that of cold water, the pump is activated for a determined amount of time. If the suitable hot water temperature is reached at the temperature sensor of the point-of-use before the time limit is reached, the system is disconnected, and if the timer reaches the time limit and the hot water temperature is not reached, the system is disconnected. |
