Before starting the circulation balancing, the circulation line must be completely vented. No more “air noises” should be perceived, e.g. at the pump. If circulation balancing has been started, no tapping may be carried out in the drinking water network concerned during the time when balancing is in progress. The flow rate must be set in such a way that the temperature spread is 5 K (e.g. 60 °C hot water temperature and 55 °C circulation return temperature).
