Apparatus for adjusting a central heating installation, particularly in respect of the heat delivery of the appertaining radiator or radiators separately, for which purpose the or each radiator is provided with a presettable valve in the supply pipe for the heating medium, such as water. The apparatus is further provided with a temperature transducer on the supply pipe and a temperature transducer on the return pipe for the heating medium, and a control unit is provided which has at least three inputs, to two of which said temperature transducers of the supply and return pipes are connected, while to the third said input a room temperature transducer is connected. Said control unit comprises a memory for storing the relationship between the relative heat delivery of the radiator and the relative mass flow of the heating medium, using as parameters the differences between supply, return and room temperatures and the heat delivery exponent of the radiator, and for storing input data, measured temperatures and calculated heat delivery, said control unit reacting to the measured temperatures to supply at the output a control signal for indication and/or valve adjustment of the mass flow in the flow pipe.
Apparatus for adjusting a central heating installation particularly with respect to the heat delivery of associated radiators which are connected to a central heating source by means of supply and return pipes for a heating medium, the supply pipe including a valve control means comprising first and second temperature transducer means for measuring the supply and return temperature of the medium respectively, a third temperature transducer means for measuring room temperature, a control unit having at least three input terminals supplied with inputs from the first, second and third transducer means, respectively, said control unit including calculating means and memory means for storing the relationship between the relative heat delivery of the radiator and the relative mass flow of the heating medium using as parameters the differences between supply, return and room temperatures and the heat delivery characteristics of the radiator and for storing input data, measured temperatures and calculated heat delivery, the control unit reacting to the input signals and the memory information for providing a control signal to an indicating means and/or to said valve control means for adjusting the flow of the heating medium into the radiator.
