If any of the Adjust buttons are pressed while any of the above temperatures are
displayed, the Panel Display immediately reverts to show the Target temperature.
As the button is pressed again, the left character of the display shows the letter “c”
(eg. c. I70 = ), indicating that further pressing of the Adjust button will “change”
the current Target temperature. As the button is pressed again, the Target
temperature is changed up or down, depending on the Adjust button pressed.

As soon as the Display Mode button is pushed, the leading “c” disappears
(eg. I60 = ) and the Target temperature takes on the new displayed value. At this
point, the Display Panel reverts to the Manual display mode described below.
Certain overriding conditions will also affect the left-most character of the Target
temperature display as shown below. For further information, refer to the
Parameter Definitions section of this manual.
