ADJUSTING THE SET POINT
3.
To adjust the set point press and release either the
WARMER or COLDER key. This will start the set point
flashing. While in this mode you can adjsut the set
point warmer or colder until the desired temperature is
reached. When adjustment is complete stop touching
the display and the set point will be saved in
approximately five seconds.
VIEWING ACTUAL TEMPERATURE
4.
In viewing temperature in these modes any offsets are
taken into account. This means that if you place a
thermistor in a known temperature, let's say ice water,
it may not read the 32°F that you would assume. If the
control offset was preset at -3°F while you placed the
thermistor in an icebath, the actual thermistor reading
when viewing actual temperature would read 35°F. In
the unit this would cause the cabinet to push itself 3°
cooler. To view pure thermistor readings you must go
into the service menu and choose the correct option.
To view the thermistor temperature, push and release
the up and down keys. The display will show the
corrected refrigerator temperature.
