This option is only available if the Return fan is selected with the Volume Matching control scheme. Select this option to control the Exhaust and Return Air Dampers only. In this control scheme, the outdoor damper is completely open while the exhaust and return dampers are modulated to control air movement to the mixing box and thus, limit the intake of fresh air.

  • Separate Outputs add two AOs (EAD-O and RAD-O) for the damper signals.
  • Common Output adds a single AO (MAD-O) to control both dampers.
  • Two Position OAD optionally adds a single BO to open the outdoor air damper when the unit is occupied and close it when it is unoccupied.
