Operating principle

The active mixing circuit controls the net thermal power passing through the circuit by mixing cold return water (coming from the end unit return pipes) with hot water from the primary production side. In full load operation the inlet gate of  the 3-way mixing valve is completely opened whereas in partial load conditions.... 

Individual components and parameters

System check 

As this mixing circuit is a so called 'active' mixing circuit, the embedded pump is able to extract hot water from the primary side by itself. In fact   Running the system check, the software will
