Communication

￿A system with simultaneous room heating and DHW heating requires maximum energy. ￿A system with a fully charged storage tank which performs only room heating requires less

energy.

￿A system which suspends room heating during DHW heating requires less energy.

As a result, three different maximum limit values can be specified: ￿Max. limit value to determine the absolute upper limit

￿Max. limit value for heating for exclusive operation of the room heating ￿Max. limit value for DHW for exclusive operation of the DHW heating

In all systems without DHW heating or without heating circuit, only the Max. limit value for the flow rate or capacity can be set.
