Information

This example validates Buildings.Obsolete.Controls.OBC.ASHRAE.G36_PR1.AHUs.MultiZone.VAV.Economizers.Subsequences.Modulation for a varying supply air temperature control loop signal. The instance mod is in normal operation, whereas for the instance modFre, the damper limits are as if the mixed air temperature were below its freezing set point.

    Added additional instance to validate the behavior when dampers are such positioned that they prevent the mixed air temperature from being below the freezing set point.

    First implementation.
