ALL WINE STORAGE

Electronic Control System
The electronic control system of your Sub-Zero wine
storage unit gives you the most accurate temperature
control for your peace of mind. You can be assured your
wine is stored at the temperature you have selected,
whether it is long-term aging or staging wine for consump-
tion that evening.
A microprocessor accurately samples the temperature
every second in each zone to be sure the temperatures
stay within one degree of your preset temperatures. t also
monitors the unit’s operation and will let you know if
service may be necessary.
TE PERATURE CONTROL
With all Sub-Zero wine storage models you have the capa-
bility of setting two distinct temperatures within the two
zones of your unit. The temperature range in each zone is
39°F (4°C) to 65°F (18°C).
Your wine storage unit has been thoroughly tested and
inspected before it was shipped from the factory. The
temperature has been preset at 45°F (7°C) in the smaller
zone and 55°F (13°C) in the larger zone.
There are two sets of WARMER and COLDER key pads on
the control panel, one for each of the two separate
temperature zones. An arrow next to the temperature in
the LED display, will indicate which temperature corre-
sponds with each zone. Refer to the illustration below.
Wine Storage Use & Care 8
The COLDER key pad on the control panel allows you to
decrease the temperature in the corresponding zone by
one degree each time you press the key pad. Similar to
the COLDER key pad, you can raise the temperature in the
corresponding zone by one degree each time you press
the WARMER key pad on the control panel.
TE PERATURE DISPLAY
The electronic control system can display temperatures in
Fahrenheit (°F) or Celsius (°C).
To convert Fahrenheit to Celsius, turn the unit off then
back on. Within the first minute after turning the unit on,
press and hold the the key pad and the UN T ON/OFF
key pad simultaneously for five seconds, then release. A
‘C’ will appear in the upper right of the temperature
readings on the LED. Follow the same procedure to
convert from Celsius to Fahrenheit.

Electronic Control System
LED DISPLAY
Electronic control system functions, such as digital
temperatures and service indicators, are shown in the LED
display, located on the control panel. The temperatures of
each zone will be visible through the glass door of your
wine storage unit. f you are using your unit frequently,
the numbers may fluctuate slightly.
UNIT ON/OFF
The UN T ON/OFF key pad on the control panel will shut
off electrical power to the wine storage unit for cleaning or
service. Your preferred temperature settings will remain
unchanged when the unit is turned back on.
LIGHTS ON/OFF
All Sub-Zero wine storage units have the capability of
having the lights on independently of the door’s opening
and closing. This will allow you to display your collection
of wine for special occasions.
To have the lights remain on in your wine storage unit
when the door is closed, press the L GHTS ON/OFF key
pad. Press the key pad again to have the lights to go off
when the door is closed.
ALAR FEATURE
f the microprocessor detects temperature fluctuations or
a faulty component, you will hear an audible beep and
the indicator will flash in the LED display on the control
panel. Also, if the unit is tied in with your home security, it
will alert this system. When the alarm feature is activated,
the indicator will be visible in the LED display. You can
deactivate the alarm and the audible beep by pressing the
key pad on the control panel. When the alarm is deac-
tivated, the indicator will not be visible in the display.
SABBATH ODE (STAR-K)
All Sub-Zero wine storage units feature the Sabbath
mode. This is for certain religious observances where the
lights need to be turned off.
To initiate Sabbath mode, while the unit is on, press the
UN T ON/OFF key pad so that ‘OFF’ is visible in the LED
display on the control panel. Your unit will be off.
Then press and hold the UN T ON/OFF key pad for 10
seconds. This will turn the unit back on and will disable
the lights. To return the unit to normal lighting, press and
release the UN T ON/OFF key pad.
f you have questions about Star-K compliance, visit
www.star-k.org.
VISUAL SERVICE DISPLAY
The electronic control system monitors temperatures as
well as the unit’s operation. f the system detects a poten-
tial problem, ‘SERV CE’ will be illuminated in the control
panel display. Before calling for service, check to see if
the condenser area needs cleaning. Refer to condenser
cleaning on page 17. f service is necessary, contact
Sub-Zero factory certified service.
Do not operate your wine storage unit for long periods
of time with the lights on. The heat from the lights will
cause the unit to work unnecessarily hard.

Wine Storage Use & Care 10
Bulk Storage Drawers—Model 427RG
TE PERATURE CONTROL
For model 427RG, the bulk storage drawers have their
own microprocessor and control panel located in the top
drawer. The preset temperature is 39°F (4°C) from the
factory, but you have the option of adjusting the tempera-
ture. The LCD display on the control panel displays the
actual temperature of both drawers in your unit.
The COLDER key pad on the control panel allows you to
decrease the temperature of the drawers by one degree
each time you press the key pad. You can raise the
temperature in the drawers by one degree each time you
press the WARMER key pad on the control panel.
ALAR FEATURE
For model 427RG, the alarm feature will sound an audible
beep if a drawer has been left open accidentally.
The ON/OFF key pad of the control panel allows you
activate or deactivate the alarm feature. When the alarm is
activated, the icon will appear in the control panel
display. When the alarm is deactivated, the icon will
not be visible.
Temperature Settings
With all Sub-Zero wine storage models you have the
capability of setting two distinct temperatures within the
two zones of your unit. While each temperature zone has a
range of 39°F (4°C) to 65°F (18°C), you can set each zone at
the exact temperature you think best—whether it’s for
consumption or for duplicating the temperatures of cellars
for long term storage.
n all instances, temperature settings are your individual
preference, and with your Sub-Zero wine storage unit,
you can be confident those temperatures will be will
maintained. The chart on page 19 offers some universally
accepted storing and serving temperatures for the most
common wines consumed today.
