Extends from Buildings.ThermalZones.EnergyPlus_24_2_0.Examples.SingleFamilyHouse.EquipmentSchedule (Example model with a schedule that overrides a schedule in EnergyPlus).

Information

Simple test case that verifies whether the schedule for the internal loads used by EnergyPlus is modified from Modelica, and the electrical equipment load that is controlled by this schedule is reported correctly.

The instance assEqu asserts that the input and output of EnergyPlus are correctly synchronized. If the output were delayed, the simulation would stop with an error.
