The unit controller shall use space temperature and space temperature setpoint to determine when to initiate requests for cooling. When the
space temperature rises above the setpoint, the unit controller shall modulate the economizer or stage the DX cooling as required to
maintain the space temperature setpoint. The first compressor shall energize after its minimum 3-minute off time has expired. If additional
