ELECTRONIC CONTROL SYSTEM
The Electronic Control System of your Sub-Zero
Built-In unit monitors and accurately displays
temperatures within one degree of your preset
temper ature. It also monitors operation of the
unit and lets you know if there’s a problem.
You’ll find the Control Center located in the
refrigerator section of all models, except Model
ICBBI-36F where it is in the freezer section. Refer
to the illustration below.
TEMPERATURE CONTROL
Your new Built-In unit was thoroughly inspected
and tested before it was shipped from the
Sub-Zero factory. Temper atures are preset at 3˚C
in the refrigerator section and -18˚C in the freezer
section. Temper atures are displayed in the Con-
trol Center display panel.
For combination units, there are two sets of
and
key pads on the Control Center, one for
the refrigerator section and the other for the
freezer section. Models ICBBI-36R, ICBBI-36RG
and ICBBI-36F have only one set of
and
key pads.
To adjust the tem per ature in either section,
depress the
or
key padson the Control
Center.
The temperature ranges are -23˚C to -15˚C in the
freezer section, and 1˚C to 7˚C in the refrigerator
section. It is normal for temperatures to fluctuate
slightly, depending on external influences such
as an open door, the degree of humidity and
room temperature.
IMPORTANT NOTE:
Always allow 24 hours
for the unit to reach the temperature you set.
POWER
All Sub-Zero Built-In models feature a
key
pad on the Control Center. This key pad will turn
off all electrical power to the unit. When the
power is off, the OFF indicator light will be vis-
ible in the Control Center display panel. This
key pad means you don’t have to shut off power
at the circuit breaker or wall receptacle. To
service or replace a light bulb, disconnect power
supply from the receptacle before changing light
bulb. The power cord is located in the far right
corner behind the flip-up grille.
ALARM FEATURE
All Built-In models have an alarm feature with an
audible chime if the door is left ajar.
The alarm will sound after 30 seconds. It can be
deactivated by depressing the
key pad. When
the alarm is activated, the
indicator will be
visible in the Control Center display panel.
ICE MAKER CONTROL
Built-In models with an ice maker feature an
key pad on the Control Center. This key pad
switches the power to the ice maker system on
or off. When the ice maker system is on, the
indicator will be illuminated in the Control
Center display panel. The ice maker can also be
turned on using the
key pad, activating the
Max Ice feature. The
indicator will be illumi-
nated in the Control Center display panel when
this feature is on. Use the
key pad to shut
down the ice maker during extended vacations.

DUAL REFRIGERATION
The Built-In line continues the Sub-Zero tradition
of superior quality and reliability. Sub-Zero pio-
neered the develop ment of our dual refrigeration
system, giving you optimum fresh and freezer
food storage in ideal self-contained sections.
Both refrigerator and freezer maintain accurate,
consistent temperatures. Dual refrigeration
keeps your food fresh longer than any other
system available.
With dual refrigeration, the freezer maintains a
constant temperature within one degree of the
temperature you set within our range of -23˚C to
-15˚C, without unwanted moisture and odor from
the refrigerator. Similarly, you can adjust the
refrigerator temperature within a range of 1˚C to
7˚C, for proper humid ity levels tailored for longer
food life expectancy.
The dual refrigeration system also means there
is no transfer of fresh food odors to frozen food
or ice. The Sub-Zero system does not freeze the
moisture out of the air in the fresh food section.
Sub-Zero dual refrigeration is also more energy
efficient than old-fashioned single refrigeration
systems. When the refrigerator is used fre-
quently during the day it does not require the
freezer to circulate its very cold, dry air to the
refrigerator. Instead, the refrigerator uses moist
air to keep fresh foods fresh and energy use
minimal.
