Recommendation: Objects requiring a COV adaption according to line size The default COV (change-of-value) of several present values is factory set for the smallest line size DN 15 – e.g. Present Volume Flow (PrVfl): ● Range DN 15: approximately 0.015…1.5 m3/h ● COV increment = 0.01 m3/h For larger line sizes, this will lead to very high data traffic on BACnet. In order to avoid this, it is recommended to adapt the COV values for the objects in the table below according to line size.
