DCV Max Vent Airflow – The maximum airflow allowed when the IAQ function overrides
the temperature control. When active, the damper modulates to the temperature
control requirement or the
DCV Max Vent Airflow , whichever is greater. This value is a
percentage of the Maximum Cooling Airflow Setpoint .

Power Fail Restart Delay – How long the controller delays normal operation after the
power is restored. This is typically used to prevent excessive demand when recovering
from a power failure. Applies to Series Fan start delay when system mode transitions
from unoccupied to occupied. A delay of no greater than 120 seconds is recommended
for Series Fan applications.
