ON/OFF
The ON/OFF mode allows the unit to be turned on and off via the
keypad. To do this, hold the key for approximately 10 seconds until
the “F” begins to flash. Release and the unit will switch modes. In the
OFF position the cabinet light will remain operational. This mode
does not disconnect power from the circuit board so it is still “live.”

CABINET LIGHT
On units with glass doors, touching the LIGHT key will turn on the
cabinet light for four hours at a time. Touching the key again will turn
the light off. Using the cabinet light for more than four hours may be
detrimental to the cabinet temperature and product. Only available
on 1175BEV, 1115WC and 1175WC models.

Adjusting the Set-point
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 adjust the set-point warmer or colder until the desired
temperature is reached. The factory recommended set-point is 38°F
for refrigerators/refrigerator-freezers and 50°F for wine coolers.
When adjustment is complete stop touching the display and the set-
point will be saved in approximately five seconds.

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, 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, 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.
