procedure.

3. Release the held key only after releasing the touched key for the
third time.

ON/OFF
The ON/OFF mode allows the unit to be turned on and off via the
keypad. To do this, hold the key for approximately 10 seconds until
the "F" begins to flash. Release and the unit will switch modes. In the
OFF position the cabinet light will remain operational. This mode
does not disconnect power from the circuit board so it is still "live."
Cabinet Light
On units with glass doors, touching the LIGHT key will turn on the
cabinet light for four hours at a time. Touching the key again will turn
the light off. Using the cabinet light for more than four hours may be
detrimental to the cabinet temperature and product. Only available
on 1175BEV, 1115WC and 1175WC models.
Adjusting the Set-Point
To adjust the set-point press and release either the WARMER or
COLDER key. This will start the set-point flashing. While in this
mode you can adjust the set-point warmer or colder until the desired
temperature is reached. The factory recommended set-point is 38°F
for refrigerators/refrigerator-freezers and 50°F for Wine Captain
When adjustment is complete stop touching the display and the set-
point will be saved in approximately five seconds.
Viewing Actual Temperature
To view the thermistor temperature, hold the WARMER key for
approximately five seconds until the "F" flashes. Release and the
display will show the corrected refrigerator temperature. For Wine
®
Captain models the display will cycle through all three zones. These
temperatures are approximate and calibrated for a cabinet in normal
ambient temperatures with some product load. Checking a
completely unloaded cabinet may result in other temperatures or
inaccurate readings.
Changing from Fahrenheit to Celsius
To change the displayed temperature from °F to °C, hold the LIGHT
key and press COLDER three times. This will change all values to °C.
When the key combination is accepted the control will change values.

entered, the degree symbol will begin to flash. When the degree
symbol is flashing the unit will allow the use of the control for
demonstrations. After not touching the unit for one minute the
display will begin to "snake" around. This is meant to alert you the
unit is in showroom mode. The unit can be left in this mode
indefinitely. If you again want to demo the control, touch any key and
the degree symbol will begin to flash. To exit this mode: This mode
needs to be exited by the same key combination as used to enter the
mode.
Service Mode
This mode has 16 different options available for service diagnostics.
To enter the mode hold the WARMER key and press the LIGHT
button three times. The display will show "0." When in this mode the
WARMER and COLDER keys will act as 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 99 and press the LIGHT key. After five minutes of not
touching any keys the mode will also exit automatically.
