SZVAV - Economizer
If the unit is configured for a modulating outdoor air damper and conditions are suitable for economizer
cooling, the supply fan will operate at minimum speed while the economizer damper modulates between
the Outdoor Air Damper Minimum Position Setpoint and 100% to satisfy the discharge air temperature
setpoint. If the economizer damper reaches 100% open and additional cooling capacity is required, the
supply fan will increase to 100% to provide additional cooling to the space.
