FIELD: heat supply systems.
SUBSTANCE: thermal control unit has thermostatic valve with output rod, inlet and outlet, and pressure and discharging passages provided with fittings for connection with supplying and discharging pipes of a heat supply system, which are interconnected with a by-pass. The valve of small hydraulic drag is interposed between the by-pass and connecting pipe inside the pressure passage. The input rod of the valve is horizontal. The drain passage receives the flush ball valve interposed between the by-pass and connecting pipe . The axis of rotation of the ball is horizontal for permitting to form the inclined passage in the vertical plane.
EFFECT: simplified design.
