Abstract
The present disclosure relates to a method for controlling a pump, wherein the method comprises the following steps: - running (501) a pump at a set pump speed (ω) based on an operating value model function (Pω(q)) corresponding to the set pump speed (ω); - determining (503) an actual operating value (P) at the set pump speed (ω); - comparing (505a, 505b) the actual operating value (P) with a maximum (Pmax) of the operating value model function (Pω(q)) and/or a minimum (Pmin) of the operating value model function (Pω(q)); and - automatically updating (507b) the operating value model function (Pω(q)) to a higher new operating value model function (Pω,up(q)) if the actual operating value (P) is higher than the maximum (Pmax) of the operating value model function (Pω(q)), and/or automatically updating (507a) the operating value model function (Pω(q)) to a lower new operating value model function (Pω,down(q)) if the actual operating value (P) is lower than the minimum (Pmin) of the operating value model function (Pω(q)).
