Balance Summary The system has been balanced by opening the flushing loops located at the top of the risers. These were then measured on the DRV's on the ground floor and proportionally balanced. The DPCV's were then set to allow a maximum flow of 0.35 L/s so that the total flow returning to the pump in idle conditions does not exceed 1.40 L/s. The pressure differential was logged and recorded from the Trend IQ in this running condition at 0.80 Bar.
