Extends from BaseClasses.PartialOperationalEnvelope (Indicates if the device operation is within a defined envelope).

Information

Model to check if the operating conditions of a heat pump are inside the given boundaries. If not, the heat pump or chiller will switch off.

Read the documentation of Buildings.Fluid.HeatPumps.ModularReversible.Controls.Safety.BaseClasses.PartialOperationalEnvelope for more information.
