Limitation of the return temperature

The heating circuit's mixing valve can be used to provide maximum limitation of the
return temperature. Minimum limitation is not supported. By contrast, the boiler sup-
ports minimum limitation with certain restrictions for all consumers. For more detailed
information, refer to subsection 9.8.3 "Minimum limitation of the return temperature".
