MAIN MENU SELECTION - "CONTROL SETUP" (1) SCREEN

This screen is accessible from the Main Menu screen
when Security is set to either "Moderate Access" or "No
Access". These setpoints are the only values that should
need to be changed in the daily operation of the unit.
After responding [OK] to changing these control setpoints,
they are written to the ACUair
back from there to be re-displayed. EPROM memory is
non-volatile and all information is retained even if the
power to the panel is lost. This process is used to confirm
that an ACUair ® control board properly receives control
setpoint changes.

· Process Control Setpoint - During Process

this setpoint.
· Process Cooling Lockout - During Process
