Diagnostic Information
User Interface Panel and Tru Protect™ System
Overview
Viking's Tru Protect™ system informs the user if the
unit is not functioning properly through both visual and
audible alerts. The LED display panel displays a steady
green light when the Tru Protect™ system is enabled.

Starting the Unit

To start the unit, push and hold for five (5) seconds the
"ON/OFF" button located on the display panel. Upon
turning the unit on, the display will read the actual
temperature inside of the unit. If the interior temperature
is greater than 99 degrees F, the display will flash 99
until the temperature drops to 99 degrees F.

Setting the Temperature Mode

The unit can display either Fahrenheit (F) or Celsius (C).
To do so, press the " °F/C" button on the display panel.

Adjusting the Temperature Control

The temperature control is fully adjustable from the low
40s to the mid 60s in the wine cellars and beverage
centers. The set point out of the factory is approximately
55 degrees F. The temperature control is adjustable from
the low 30s to the high 40s in the refrigerated drawers.
The set point out of the factory is approximately 38
degrees F. The range, whether it be for wine cellars
and beverage centers or refrigerated drawers, allows
flexibility of temperature preferences and provides the
ideal wine aging or food storing temperatures. The
temperature can be lowered or raised by first pressing
the "SET" button on the display panel. A "SET" icon
will be displayed. This icon will turn off 10 seconds
after completing the adjustments. Pressing either the
"WARMER" or "COLDER" buttons will raise or lower the
set temperature by one (1) degree F or C (depending
on the setting). NOTE: As with any refrigeration product,
there is a slight temperature variance at different
locations within the cabinet.
