This is the process heater autotune screen.
(See page 4-22 for detailed information on
the autotune function.) The autotune pro-
cedure should be performed when setting
up the system the first time or if the con-
trol is inconsistent. Autotuning may take a
minute or so to complete. When finished,
the display will read “don”. The new PID
values are automatically saved (to screens
11, 12, and 13).
This is the temperature units screen. It is
used to change the temperature display
from °F to °C or °C to °F.
