3.10 Changing the Temperature Display Resolution The controller is programmed to display temperature
with 0.1
o
C resolution. The controller can be changed to 1
o
C resolution if by following the procedure
below (the display can also be changed to read in
o
F, call for information). There are two reasons to
change the display resolution:
1) To enter a setpoint faster (the display scrolls 10X faster in 1

mode than in 0.1
o
mode).
2) To display temperatures above 999.9
