Units must be equipped with a supply air variable frequency

When the supply air VFD is operating at lower speeds the
amount of fresh air pulled into the system may not meet
minimum outdoor air requirements. Based on input from
the O.A. control, the Unit Controller modulates outdoor air
dampers to maintain a constant amount of fresh air
regardless of blower speed.
