for details on which listed heat meters fulfill this criterion and can be used for limitation pur- poses.

In case of battery-operated heat meters in particular, please note that some makes react with communication intervals if they are polled too frequently. Other makes could use up their bat- teries too quickly. The technical documentation TV-SK 6311 provides more details on these matters.

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.

Flow rate limitation

The settings which are to made for the flow rate limitation are mainly contained in function block FB30 as function block parameters. Only after selecting the type of limitation “At“ for out- door temperature dependent limitation (which automatically means a 4-point characteristic), four outdoor temperature dependent maximum limits for heating need to be set in the 4-point characteristic menu. After selecting “- - -“, set Maximum limit for the system, Maximum limit for heating and Maximum limit for DHW, Minimum limit and the Limiting factor that appear in this order. The Limiting factor determines how strongly the controller responds when the limit values are exceeded in either direction.
