Flow temperature limit
The following parameter activates the flow temperature limitation:

Setting the value to which the flow
temperature should be limited
Table 53: Settings - Flow temperature limit
The current flow temperature can be limited by the flow temperature limiter. This allows the heating
temperature to be limited as required in certain situations. For example, if an underfloor heating
system is not to heat above a certain value to protect the floor coverings, the heating temperature
can be limited by the flow temperature limitation.
The flow temperature limitation requires a second sensor on the flow itself. This sensor measures the
current flow temperature. The object which detects the flow temperature is then connected in a
group address to the object for the flow temperature of the temperature controller. This then limits
the flow temperature according to the set parameters.
