Maximum limitation of the flow temperature setpoint
The setting will ensure that the flow temperature setpoint will not exceed a maximum
level.
Maximum limitation is
not
to be regarded as a safety function as required with
underfloor heating systems, for example.
If the flow temperature setpoint demanded by a consumer reaches the maximum limit
and the outside temperature falls, the flow temperature setpoint will be maintained at
that limit, in other words, it will not be allowed to exceed it.

When the outside temperature varies, the room temperature changes at different rates,
depending on the building's thermal storage capacity.
The above setting ensures that the generation of the composite outside temperature
will be matched to the type of building construction. Also refer to "Composite outside
temperature” in section "Functions without settings".
