Attached is information regarding the Trene Tracer DDC control
system which will be utilized on this project. The issue which you
asked about will be handled in the programming of the controls.
The systems will go into night setback and the outside air dampers
will close during unoccupied hours. The dampers will be allowed to
open as needed to maintain unoccupied temperatures if the outside
air can be utilized.
If you have any further questions, please call me.
