Abstract: A circulation pump assembly for a heating and/or cooling system includes an electric drive motor (108) and a connected pump housing (106) in which at least one impeller (118) is situated and which comprises a first inlet (112) and a first outlet (114). The pump housing (106) includes a second inlet (122) which is connected in an inside of the pump housing (106) at a mixing point (130) to the first inlet (112). A regulating valve (134), which is designed for regulating the mixing ratio of two flows mixing at the mixing point (130), as well as a control device, which controls the regulating valve (134) for regulating the mixing ration, are arranged in the pump housing (106). A hydraulic manifold is provided with such a circulation pump assembly.

Abstract: A hydraulic manifold for hydraulic heating and/or cooling systems includes a feed conduit and a return conduit. The feed conduit includes at least one feed connection and the return conduit includes at least one return connection, for the connection of a load circuit. The manifold has a modular construction with a main module and connected load module(s). The main module includes a section of the feed conduit and/or of the return conduit as well as an electric connection. The load module includes a section of the feed conduit with a feed connection, and/or a section of the return conduit with a return connection, as well as at least one regulating device for regulating the flow through a load circuit connected to the feed connection and to the return connection. The main module includes a manifold control device for the control of the regulating device in the load module(s).

Abstract: A hydraulic manifold for a hydraulic heating and/or cooling system includes a feed conduit (212) and a return conduit (216). The feed conduit (212) includes at least one feed connection (258), and the return conduit (216) includes at least one return connection (260), for the connection of a load circuit (228). A load module (204), in which a section of the feed conduit (212) with the feed connection (258), and a section of the return conduit (216) with the return section (260) are formed, includes at least one mixing device with a pump (232) and with a regulating valve (230), to admix fluid from the return connection (260) to a fluid flow from the feed conduit (212) to the feed connection (258). The section of the feed conduit (212) and the return conduit (216) in each case include an additional contact for connection with a further load module.

Abstract: A hydraulic heating and/or cooling system hydraulic manifold is constructed in a modular manner with a main module (2). At least one load module (4) is connectable to the main module (2) and includes a hydraulic connection (22, 24) for a load circuit, and a closed-loop control device (26, 28) controlling flow through the load and for connection to an identically configured further load module (4). The at least one load module (4) includes a circuit board (44) which extends between a first (34) and a second axial end (36) of the load module (4) and which at its first (34) and second end (36) have electrical couplings (50, 52) which correspond to one another. The electrical coupling (52) at the second end (36) of the circuit board (44) can electrically conductively engage with an electrical coupling (50) at the first end (34) of the further identical load module (4).

Abstract: A hydraulic valve includes a valve housing (4) with an inside that defines at least one first flow path (7), and with a valve insert (16) which is arranged in the inside of the valve housing (4). The valve insert (16) includes a movable valve element (14) situated in the first flow path (7). An infrared temperature sensor (46) is arranged on or in the valve housing (4) and is directed onto a surface of the valve insert (16) or a surface of a thermal conductor (48) connected to the valve insert. A hydraulic manifold may be provided with such a hydraulic valve.
