SETUP
The series F4SH has been setup by Associated Environmental Systems. The internal dip switch
has already been set. It has also been tuned for you chamber and should not require any changes
in the PID parameters.
QUICK USE GUIDE
The best way to learn about the Series F4SH is to read the Series F4 User’s Manual. The
following section is not intended to replace the manual, it is to serve as a quick use guide to
check and use the chamber without extensive reading of the Series F4 Manual.
After switching the chamber power on, you will notice numbers on upper display of the F4
controller. This is the actual temperature inside the chamber. The units will be determined by
the led located by °F or °C. Lower display shows various information by pressing navigation
key up or down and is used for changing set point or setup. SP1 is the set point. To change set
point select SP1 by moving cursor up or down using navigation key up or down. Press right
arrow key to enter then press up or down key until desired temperature is displayed. Then press
right arrow key to enter that value. New set point has been established. Press Heat and Cool
switches on control panel of chamber.
If you are having difficulty understanding any of the above, read chapters 2 & 3 of the F4 User’s
Manual.
