Use UP/DOWN keys to set desired range.
During the course of time there may be a
slight offset in the actual temperature and
the temperature displayed.
EXAMPLE:
If the actual temperature is
20.0ºC and the temperature on the
controller shows 22.0ºC set this

parameter to -2.0 C and once out of this
mode, the temperature will display

EXAMPLE:
If the AFT set point is set at
