103 Minimum limitation of the flow temperature setpoint
104 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.

Type of building construction

•
Consideration is given to the building's thermal dynamics
Enables the control system's response to be matched to the type of building
construction.
1. Press the operating line selection buttons to select operating line 105.
2. Press the + / – buttons to select the type of building construction.
Setting range
0 / 1
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".
Entry:
Heavy building structures: The room temperature will respond slower to outside

temperature variations
Light building structures: The room temperature will respond quicker to outside

temperature variations
•
Heavy building structures:
Buildings with thick walls or with external insulation
•
Light building structures:
Buildings with a light envelope
