Information

This model validates Buildings.DHC.ETS.Combined.Subsystems.WatersideEconomizer in a configuration where the primary flow rate is modulated by means of a two-way valve (see hexVal), and in a configuration where the primary flow rate is modulated by means of a variable speed pump (see hexPum).
