VIEWING ACTUAL TEMPERATURE
4.
In viewing temperature in these modes any offsets are
taken into account. This means that if you place a
thermistor 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.
CHANGING FROM FAHRENHEIT TO

CELSIUS

SHOWROOM MODE
6.
This mode is designed to show units in a display
environment. When in this mode the only functions will
be the control and cabinet lights. The compressor,
fans, etc. will not operate. To enter 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. To exit this mode, interrupt power to the
unit.
SABBATH MODE
7.
The U-line Series of models offer a Sabbath mode for
users who require this functionality during Sabbaths.
Sabbath mode disables system responses to user
initiated activities and all external functions; including
lighting, display and audible alarms. The unit will still
maintain internal temperatures and set points.
SERVICE MODE
8.
This mode has 28 different 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 enter
a 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.
