2.1 Introduction: TruProtect
™
Control Features
2.1.1 TruProtect
™
System
Vikings exclusive TruProtect™ refrigeration monitor governs the intuitive user interface panel. The Tru
Protect™ system informs you if the unit is not working properly through both visual and audible alarms.
A message center is located on the right side of the user interface over-lay.
The TruProtect™ System can be enabled or disabled by pressing and holding the “Set” keypad for five
(5) seconds, the audible alarm will sound three (3) times and the message center will display either a
green “on” (enabled) or amber “off” (disabled) icon.
2.1.2 Initial Start Up
Plug unit into a power receptacle. The display on the user interface panel should beep and an amber
power failure will show on the message center. This is normal at initial start-up as the wine cellar was
operated for quality checks at the factory.
To clear this code, simply depress the “On/Off” keypad for five (5) seconds to turn the control off. Press
the “On/Off” keypad once again to start the wine cellar with a fresh display.
If the wine cellar has recently been stored in temperature exceeding 99˚F the display will only read
up to 99˚F. This will be seen only if the thermistor still sense’s that extreme temperature. This is not a
concern, as soon as the wine cellar starts cooling the thermistors will display the compartments tempera
-
tures as it cools.
2.1.3 Turning the Unit On & Off
Press and hold the “On/Off” keypad for five (5) seconds to turn the unit on and off.
When “off” the display will be blank and the refrigeration system will be inoperative. The lights will
still function, however they will time-out after 15 minutes if the door is left open or the display lighting
is on to prevent overheating.
2.1.4 Display Temperature
The temperature display for both the upper and lower compartments is located on the user interface
panel on the face of the control box inside the upper compartment.
Compartment temperature is displayed as actual “real time” temperatures. This is unique to competitive
models that display set-point or lock-in temperatures.
Slight temperature variations are a normal characteristic of this wine cellar.
It is important to note that variations of display temperature will appear due to certain factors. A couple
of examples would be the amount of door openings, and length of time into either an “off” or “defrost”
cycle.
