Display
The Main Display has 9 characters (7 seven--segment
characters and 2 nine--segment characters), 2 decimal
points, 2 commas, and a degree symbol. The display is
used to provide the user setpoint and refrigerated

comma icons are used instead of decimal points. When
English Units is selected in the Functional Parameters,
decimal points are used.
Temperature display is right justified, with unused digits
blank. A negative sign will be displayed for all setpoint
and box temperatures below zero. A positive sign will be
displayed for all setpoint and box temperatures above
0°F(--17°C). 0° will not have a sign in front of it.
