The invention discloses a control unit for variable-frequency constant-pressure water supply. The control unit comprises an impounding reservoir, a pumping unit and a water supply network; water in the impounding reservoir is pumped by the pumping unit and is supplied to the water supply network; the pumping unit is connected with a controller; the water supply network is provided with a water pressure detector; the controller is provided with a PID (proportion integration differentiation) regulator; the PID regulator is connected with the pumping unit through a frequency converter; the rotational speed of the pumping unit is controlled by the PID regulator according to water supply network water pressure detected by the water pressure detector through the frequency converter to realize constant-pressure variable water supply. Through the control unit disclosed by the invention, according to the change of the water supply network water pressure, the rotational speed regulation is performed on the pumping unit, and therefore the constant-pressure variable water supply is realized; the control unit has the advantages that the pressure is stable, and the energy-saving effect is obvious.
