Economizer Cooling + DX is a mode of operation when both economizer and DX cooling is active. If
actively economizing, outdoor air damper is 100% and supply fan speed reaches 100% then DX cooling
will be added if the unit is not satisfying space cooling requirements.
If DX cooling is active and economizer cooling enables, the control will transition to increase the economizer damper above the minimum position to 100% to satisfy space cooling while decreasing DX cooling. DX cooling will steadily be removed as long as economizer cooling is able to satisfy the cooling load. The supply fan operates at the lowest speed possible during the transition
