ELECTRONIC CONTROL SYSTEM
The sophisticated electronic control system
of your Integrated unit provides you with the
b
est control of your refrigerated foods. By
maintaining recommended refrigerator and
freezer temperatures, you can keep food safe
a
nd retain the best quality possible.
A
microprocessor accurately controls the
temperature of the cooling zones. It samples
the temperature every second and makes
adjustments to maintain the temperature you
have indicated.
The electronic digital control panel is located
on the top of the tall units and in the top
drawer of the base units. All of the essential
controls and information are displayed in this
easy-to-reach-and-see panel. Refer to the
illustrations below for location of the electronic
control panel. Note that for single zone units
and units that cannot support an ice maker,
the electronic control panel will be slightly
different.
LCD DISPLAY
The liquid crystal display (LCD) located on the
electronic control panel shows the actual
temperature of different zones in your unit.
If there is a temperature or ice maker problem,
you’ll be alerted by a flashing SERVICE indica-
tor light in the LCD display.
TEMPERATURE CONTROL
I
ntegrated units are factory preset to maintain
refrigerator zones at 38˚F (3˚C) and freezer
zones at 0˚F (-18˚C). The temperature range for
r
efrigerator zones is 34˚F (1˚C) to 45˚F (7˚C) and
the temperature range for freezer zones is -5˚F
(-21˚C) to +5˚F (-15˚C).
For combination units, there are two sets of
WARMER
and
COLDER
key pads on the elec-
tronic digital control panel. One is for the
upper refrigerator zone and the other for the
lower freezer drawers. Models 700TR and
736TR also have two sets of key pads, one for
the upper zone and the other for the drawers.
Single zone refrigerator and freezer units have
only one set of
WARMER
and
COLDER
key
pads.
The
COLDER
key pad allows you to decrease
the temperature of a selected zone in one-
degree increments.
Similar to the
COLDER
key pad, you can raise
the temperature in any zone in one-degree
increments by pressing the
WARMER
key pad.
IMPORTANT NOTE:
Always allow 24 hours
for the unit to reach the temperature you set.
