This demonstrates the importance of system automation and the commissioning phase for energy-efficient operation. The study showed that KPIs were up to 39% exaggerated due to unfavourable parameterisation. If the optimum parameterisation cannot be determined on the basis of preliminary technical considerations, simulation-based variant studies are a suitable method for identifying a sound parameterisation. This is exemplified for some parameters in this article.enheat pumpcontrolcommissioningsystem automation000 Informatik, Informationswissenschaft, allgemeine Werkeconference paper
