Abstract
A hydraulic construction unit for a heating facility or air-conditioning facility, includes a return connection (20) and a first feed connection (16) for a heating circuit (6), with a heat source outlet (12) fluid conducting connected to the return connection. A heat source inlet (14) is fluid conducting connected to the first feed connection and to a circulation pump assembly (28) in a flow path between the return connection and the heat source outlet (12) or in a flow path between the heat source inlet and the first feed connection. A second feed connection (18) for a second heating circuit (8), is fluid conducting connected to the heat source inlet and to the return connection. A mixing valve (54) is arranged in a flow path from the heat source inlet to the second feed connection and/or in a flow path from the return connection to the second feed connection.
