ABSTRACT:
The invention relates to a control unit comprising two bodies, one of which is located in a main fluid-distributing section, such as a hot water heating system. A shunt valve in this main section body provides for shunting the hot water, of a boiler in the main section, between different channels which are enclosed within the two bodies. The second body section is located in a group flow-distributing section, and may be used in conjunction with a circulating pump. The two bodies are connected to each other via a mechanical heat-blocking device, made of a material having a heat conductivity figure which is lower than .lambda.=1.00 kcal/m h .degree.C. This heat-blocking device also establishes a communication for fluid flow between the channels, enclosed in the two bodies.
