Internal calculation of outside temperature forecasts:
An outside temperature forecast is generated based on past outside temperatures.
A persistency forecast is used to this end. This means that the measured course of
the past 24 hours will be repeated within the next 24 hours. At the start of the
forecast, however, a correction using the currently measured outside temperature
value is made. The calculation is carried out as part of the function for the next 64
hours.
The block conducts the internal calculation of outside temperature even if the
interface for the use of an external outside temperature forecast is used.
Use of an external outside temperature forecast (option):
If there is an external outside temperature forecast for the building location, e.g. by
a meteorological service, it can be provided to the block as a time profile (1 value
per hour). If there is no external forecast or if the forecast is wrong, the block
changes over to internal forecasting upon the next optimization.
