VIEWING ACTUAL TEMPERATURE
In viewing temperature in these modes any offsets are
taken into account. This means that if you place a therm-
istor in a known temperature, let’s say ice water, it may
not read the 32°F that you would assume. If the control
offset was preset at -3°F while you placed the thermistor
in an icebath, the actual thermistor reading when viewing
actual temperature would read 35°F. In the unit this would
cause the cabinet to push itself 3° cooler. To view pure
thermistor readings you must go into the service menu
and choose the correct option.
To view the thermistor temperature, push and release the
up and down keys. The display will show the corrected
refrigerator temperature.
SHOWROOM MODE
This mode is designed to show units in a display environ-
ment. When in this mode the only functions will be the
control and cabinet lights. The compressor, fans, etc. will
not operate. To enter/exit this mode hold the light key
and the power key for 5 seconds. The display will flash
once and beep and the degree symbol will begin to flash.
When the degree symbol is flashing the unit will allow the
use of the control for demonstrations. The unit can be left
in this mode indefinitely.
SERVICE MODE
This mode has options available for service diagnostics.
To enter the mode hold the hidden key for 10 seconds.
The display will show “0.” When in this mode use the up
and down arrows to select the desired option. The LIGHT
key is the ENTER key and will initiate the function. If
changing a setting, you must press the LIGHT key again
to retain the changed setting. To exit the service mode
scroll to option “0” and press the LIGHT key. After five
minutes of not touching any keys the mode will also exit
automatically.
