II - Model KN-8828B-2K
Color LCD Display
Auto Coffee Roaster with Manual Control
The KN-8828B-2K allows easy roasting of the coffee for new users, yet
supplies complete manual control for those who become advanced in their
roasting knowledge and are looking for a specific taste or roast level. Roast
Profiles can be saved for later use as well. Physically, it is the same as our other
model. The only difference is the user interface of the control panel.
In the Auto mode the user will find that with just three pushes of the START
button the coffee roasting process will begin. In the manual mode, all parameters of the roasting process
can be controlled by the user. These modes and how to operate them are fully described in this chapter.
UNDERSTANDING THE LCD DISPLAY
The first thing that you will notice is the colorful LCD display panel. This is the interface between the
user and the roaster. Let’s begin by understanding what is displayed here. Detailed instructions on how to
use the various functions of the KN-8828B-2K will be found on pages 15 through 17.
NOTE
: The display components vary depending on which mode is in use. Only functions that are
currently available will be illuminated.
When first plugging the KN-8828B-2K roaster into an outlet the user is given the choice of whether
to enter “Auto” or “Manual” mode.
TIME
The countdown
timer will eject
the beans if it
reaches 00:00.
Format is mm:ss.
TEMPERATURE
If the roast reaches
the Target Tempera-
ture the beans will be
ejected. Also shows
the actual roasting
chamber temperature.
FAN SPEED
Displays main
exhaust fan
speed. Each bar
represents 25%.
HEATING ELEMENT
This displays the level of
power produced by the
heating element. Each
bar represents 10%.
The up and down “Chevrons” are used to
raise and lower values of various
parameters such as time and fan speed.
SELECT
The circular “Select” arrow
cycles through the display
to select which parameter to
adjust or display.
Powers up the machine,
selects modes, and allows
the machine to be stopped.
Enters the selected mode
and then begins to roast.
During a roast this will eject the
beans and begin the cooling
mode. During programming
this works as an escape key,
taking you back one step in the
process, abandoning changes
made up to that point.
