.Buildings.Examples.VAVReheat.BaseClasses.Controls.SupplyAirTemperature

Information

This block implements the control logic for the supply air temperature, as described in the control sequence VAV 2A2-21232 of the Sequences of Operation for Common HVAC Systems (ASHRAE, 2006).

The heating coil valve, outdoor air damper, and cooling coil valve are modulated in sequence to maintain the supply air temperature set point. A deadband between heating and economizer cooling is also modeled.

Note that the economizer lockout when the outdoor air temperature is higher than the return air temperature is implemented in Buildings.Examples.VAVReheat.BaseClasses.Controls.Economizer.
