The Turbo Air® 3000 Centrifugal Compressor Compressor Handbook

The Control System
Auto
This key launches the compressor automatic control mode enabling it to respond
automatically to changes in system demand per a pre-selected control method.
(The control method for your system was determined at the time of order and is
based on the specific application. For information on control strategies and the
methods available, refer to the Control Logic Appendix.)
Unload
This key disables the Auto mode and unloads the compressor by opening the blow off
valve and closing the inlet guide vanes. The system continues to run but does not
respond to changes in air system demand until someone presses the Auto key.
Set Points
Pressing this key displays the lists of set points you can open and change depending on
your level of access. The opening Set Points screen below shows the four access levels.
