modelDedicatedDampersPressure
Separate dampers for ventilation and economizer, with differential pressure sensor
Extends from Buildings.Templates.AirHandlersFans.Components.Interfaces.PartialOutdoorSectionDedicatedDampers (Base class for modeling separate dampers for ventilation and economizer).
Information
This model represents a configuration with an air economizer and minimum OA control with a separate minimum OA damper and differential pressure control.
