Selection of Calculated weather compensated option:
Dependent parameter(s):
Calculation formula
Options:
Heating curve
Custom
This parameter specifies the method used to determine the currently required supply
setpoint temperature based on the outside temperature. The relationship between the
outside temperature and the supply temperature is depicted by a curve.
•
Heating curve: A heating curve based on the nominal values (design values) for the
heating is calculated. These nominal values stem from the basic planning for the
heating system and are based on the design point. The heating curve can be seen on
the web user interface for the module. The values for the curve cannot be changed
directly.
•
Custom: The shape of the curve can be set as required by entering the points.
Selection of Heating curve option:
Dependent parameter(s):
Nominal outside temperature
Options:
The outside temperature at the design point is specified using this parameter. This is
normally the lowest outside temperature for which the heating system is designed.
This information is used to calculate the heating curve.
Nominal room temperature
Options:
The room temperature at the design point is specified using this parameter. This
value is used to calculate the heating curve and has no relationship to the actual
room setpoint temperature used.
-100...-14...100 °C
