to flash. Release the key and the unit will switch
modes.
This mode does not disconnect power from the
circuit board si it is still “LIVE”.
Viewing Actual Temperature
In viewing temperature in these modes any offsets
are taken into account. This means that if you
place a thermistor in a known temperature, ice
water for example, it may not read 32° F that you
would assume. If the control offset was preset at
-3° F while you placed the thermistor in an ice
bath, the actual thermistor reading wheb viewing
actual temperature would read 35° F. In the unit this
would cause the cabinet to push itself 3° cooler. to
vire pure thermistor readings you must go into the
Service Menu and choose the correct option.
To view the thermistor temperature, hold the
WARMER key for approximately five seconds until
the “F” flashes. Release and the display will show
the corrected refrigerator temperature. For Wine
Cooler models, the display will cycle through all
three zones. These temperatures are approximate
and calibrated for a cabinet in normal ambient
temperatures with some product load. Checking a
completely unloaded cabinet may result in other
temperatures.

°C, hold the LIGHT key and press COLDER three
times. This will change all values to °C. When the
key combination is accepted the control will change
