If controlling the Outdoor Air Damper to an airfl ow setpoint, this
screen allows you to set the design Minimum Outdoor Air CFM
Setpoint. The Deadband controls the rate of change for the damper
signal. As OA CFM moves further from setpoint within this window,
the damper makes a larger change.

If doing airfl ow control of the outside air (OA) damper, the Max
OA KCFM Setpoint (K = 1000) is the maximum airfl ow that the
unit will provide during IAQ CO
2
override operation when the CO
2
level is equal to or greater than the Max CO
2
Setpoint.
Under this control, the OA damper will not open more than the Max
Econo Position, so that should be set to 100% so as not to limit the
CFM control. If not doing airfl ow control, only use the Max Econo
Position to limit the damper during high CO
2
operation.

The Min CO
2
Setpoint is the threshold CO
2
level at which the Econo-
mizer Min Damper Position (Setpoint Screen #30) will begin to be
reset higher. The Max CO
2
Setpoint is the CO
2
level at which the
Economizer Min Damper Position will be reset to the Econo Max
Pos In High CO
2
(Setpoint Screen #33). In between those CO
2
lev-
els, the Economizer Minimum Position will be proportionally reset
between the values set in Setpoint Screens #30 and #33.
