P-F
C/F Selection:
The C/F Selection allows choosing either
the Celsius or Fahrenheit scale. If using the controller to
control a process other than temperature using the cur-
rent/voltage input model, the C/F Selection is not impor-
tant because the scaling is done using the lower limit of
the input range and upper limit of input range parame-
ters, and the indication is in engineering units.
Setting: °C or °F
FUZY
Fuzzy Logic Control:
Employing Fuzzy Logic Control in
addition to PID control eliminates system overshoot and
effectively suppresses fluctuation of the process vari-
able due to external disturbances. This function may be
enabled even during auto-tuning. Note that fuzzy control
is not effective in units with dual outputs, due to the
complexity of the process. Fuzzy control is also inhibited
while the Ramp/Soak function is in operation.
