FIELD: control; regulation.
SUBSTANCE: group of inventions relates to a circulation pump unit for a heating and/or cooling system comprising drive motor (108) and pump housing (106) connected thereto, in which at least one impeller (118) is arranged. Impeller (118) has first inlet (112) and first outlet (114). Pump housing (106) has second inlet (122) which is connected to first inlet (112) inside pump housing (106) at mixing point (130). Inside pump housing (106) there is regulating valve (134) configured to adjust the component mixing ratio of two flows mixed at mixing point (130) and control device (140) for controlling regulating valve (134) to adjust the mixing ratio. Control device (140) is mounted in electronics housing (110) on drive motor (108). In housing (110), there are electronic components for adjusting drive motor (108).
EFFECT: inventions are aimed at providing a simple device for a heating and / or cooling system.
