DANGER

Electrocution can cause death or serious injury. Burns from hot or cold surfaces can cause serious injury. Take precautions when servicing this unit.

Disconnect the power source.

Do not stand in standing water when working around electrical appliances.

Make sure the surfaces you touch are not hot or frozen.

Do not touch a bare circuit board unless you are wearing an anti-static wriststrap that is grounded to an electrical ground or grounded water pipe.

Handle circuit boards carefully and avoid touching components.

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.

CHANGING FROM FAHRENHEIT TO CELSIUS

NOTE: When touching key combinations in which you hold one key and press another three times it is important to carefully follow the procedure.

1.Hold the desired key.

2.Press the other key three times.

3.Release the held key only after releasing the touched key for the third time.

Except as noted, these functions are available on all models.

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.

IMPORTANT

This does not apply to ADA24R glass door units. The light and display are always off when the glass door is closed.

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.

To change the displayed temperature from °F to °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 values.

SHOWROOM MODE

This mode is designed to show units in a display environment. When in this mode the only functions will be the control and cabinet lights. The compressor, fans, etc. will not operate. To enter this mode hold the COLDER key and press the LIGHT button three times. Once entered, the degree symbol will begin to flash. When the degree symbol is flashing the unit will allow the use of the control for demonstrations. After not touching the unit for one minute the display will begin to “snake” around. This is meant to alert you the unit is in showroom mode. The unit can be left in this mode indefinitely. If you again want to demo the control, touch any key and the degree symbol will begin to flash. To exit this mode: This mode needs to be exited by the same key combination as used to enter the mode.

SERVICE MODE

This mode has 16 different options available for service diagnostics. To enter the mode hold the WARMER key and press the LIGHT button three times. The display will show “0.” When in this mode the WARMER and COLDER keys will act as up and down arrows to select the desired option. The LIGHT key is the ENTER key and will enter a function. If changing a setting, you must press the LIGHT key again to retain the changed setting. To exit the service mode scroll to option 99 and press the LIGHT key. After five minutes of not touching any keys the mode will also exit automatically.

DISPLAY TOGGLE

On glass door units the display normally stays on all the time. To have the display go off with the door, press the up arrow and touch the ON/OFF key three times. The °F sign will flash to let you know the mode has been accepted. This mode can be toggled on or off by the same key combination. To see if the display should be staying on 100% or turning off with the door, you can check service option 8. Only available on 1115WC and 1175WC.

BLACKOUT MODE

Hold the LIGHT key for 10 seconds until the °F starts flashing. When released, the unit will beep once and the display and cabinet light will shut off. It will stay off for 36 hours, at which time it will automatically
