Abstract: FIELD: construction. 
     SUBSTANCE: device (1) comprises an inlet channel (2) for cold water, an inlet channel (3) for hot water, a supply channel (4) for mixed water, a mixing device (5) equipped with the first inlet fitting (6) made with the possibility to be hydraulically connected to the inlet channel (2) for cold water, the second inlet fitting (7) made with the possibility to be hydraulically connected to the inlet channel (3) for hot water, and an outlet fitting (8) for mixed water. The mixing device (5) additionally comprises a mixing chamber (9) from which the outlet fitting (8) for mixed water comes out. The mixing device made with the possibility of supplying from the outlet fitting for mixed water a mixed water stream having a supply temperature intermediate between the cold water temperature and the hot water temperature. The device (1) additionally contains a valve device (10) and a bypass (20). The valve device is made with the possibility of and is intended for selective operation in at least the first and second configurations. The device (1) in the first configuration provides the possibility of directing the mixed water into the supply line of a water treatment complex, and the second configuration provides the possibility of directing only hot water into the supply line of a water treatment complex to perform thereby the thermal disinfection treatment of the complex from Legionella. The mixing assembly comprises a hollow housing in which at least the following is made: an inlet tract for cold water, an inlet tract for hot water, a supply tract for mixed water, a mixing section, a valve section, a bypass. The valve device is made with the possibility of and intended for selective operation at least in the first and the second configurations. In the first configuration, the assembly provides the possibility of directing the mixed water into the supply line of a water treatment complex, and the second configuration provides the possibility of directing only hot water into the supply line of a water treatment complex to perform thermal disinfection of the complex against Legionella. The method for mixing hot water and cold water with forming thereby the mixed water stream includes the following stages: the presence of a device (1) or an assembly is ensured, the inlet channel (2) for cold water of the device or the inlet opening for cold water of the assembly is hydraulically connected to a cold water source, the inlet channel (3) for hot waterof the device or the inlet opening for hot water of the assembly is hydraulically connected to a hot water source, the output channel (4) of the device or the output tract of the assembly is hydraulically connected to the supply line for mixed water, located in the water treatment complex downstream relative to the device or the assembly, the valve device (10) operation in the device (1) or the assembly is ensured selectively in the first or the second configuration. 
     EFFECT: device, assembly, and method for mixing water treatment complexes with the function of disinfection against Legionella are provided.
