A method for an automatic balancing called dynamic automatic balancing of the input pressure of one or more thermal regulation element(s) integrated into a branch of a hydraulic network subjected to a substantially constant pressure differential (ΔP) including a balancing flap valve including an inlet and an outlet, which can be mounted downstream of a thermal regulation element integrated into a branch of a hydraulic network subjected to a substantially constant pressure (ΔP), and including: - means for measuring a characteristic magnitude of the fluid passing through the balancing valve, - means for controlling the positioning of the flap of the balancing valve, - data storage means in which are stored intrinsic and extrinsic parameters of the balancing valve, - independent processing means arranged to perform the automatic balancing, in the branch from the values of the characteristic magnitude of the fluid measured by the measuring means, the control means and the data stored in the storage means the method being characterized in that it comprises, in this order, the steps of: - waiting, after a first determined time, for the stabilization of the flowing of the fluid through the balancing valve, this time being parametrizable and preferably equal to 30 minutes, - determining the flow rate, deducing therefrom the pressure differential (ΔP), - if the pressure differential (ΔP) is comprised in a determined range of values for example at plus or minus 5% of the value of the reference pressure differential (ΔP ref): - returning to the first step consisting of waiting after a first determined time, otherwise: - calculating the characteristic coefficient of the dimensioning of the hydraulic network and of the corresponding characteristic coefficient (Kv) of the dimensioning of the balancing valve, - positioning the flap of the balancing valve on its position corresponding to the characteristic coefficient (K v) of the dimensioning of the balancing valve, - waiting after a second determined time then returning to the beginning of this step, this time being for example parametrizable equal to five minutes. - means for measuring a characteristic magnitude of the fluid passing through the balancing valve, - means for controlling the positioning of the flap of the balancing valve, - data storage means in which are stored intrinsic and extrinsic parameters of the balancing valve, - independent processing means arranged to perform the automatic balancing, in the branch from the values of the characteristic magnitude of the fluid measured by the measuring means, the control means and the data stored in the storage means - waiting, after a first determined time, for the stabilization of the flowing of the fluid through the balancing valve, this time being parametrizable and preferably equal to 30 minutes, - determining the flow rate, deducing therefrom the pressure differential (ΔP), - if the pressure differential (ΔP) is comprised in a determined range of values for example at plus or minus 5% of the value of the reference pressure differential (ΔP ref): - returning to the first step consisting of waiting after a first determined time, - calculating the characteristic coefficient of the dimensioning of the hydraulic network and of the corresponding characteristic coefficient (Kv) of the dimensioning of the balancing valve, - positioning the flap of the balancing valve on its position corresponding to the characteristic coefficient (K v) of the dimensioning of the balancing valve, - waiting after a second determined time then returning to the beginning of this step, this time being for example parametrizable equal to five minutes.
