Abstract: The invention relates to a device for influencing the room climate which offers convenient operation at low costs with regard to procurement, installation, and ongoing operation, in order to influence the room climate in heated or air-conditioned rooms while avoiding unnecessary energy losses, and which expands the application range in the room air conditioning by means of a simple retrofitting possibility. According to the invention, the control apparatus for the room temperature is integrated into an electrical measuring and display apparatus, which is intended as a room operating apparatus for measuring, displaying, evaluating, and providing room climate values, and adjustments to the control apparatus are made by means of the room operating apparatus.

Abstract: A flow-control valve has a housing having first and second input ports and respective first and second output ports for respective first and second separate fluid streams and formed between the first and second port with first and second valve seats. Respective first and second valve bodies are axially shiftable in the valve seats, and a coupling element connected axially between the valve bodies moves the valve bodies axially jointly. A diaphragm between the first piston and the housing defines an axially inner compartment into which the first input port opens and between the diaphragm and the housing an axially outer compartment. The first valve body is formed with a passage extending through the first valve body and having an axially extending part opening into the outer compartment and a transversely extending part opening into the housing between the first seat and the first output port.
