2. Controls and Adjustments

a)Default Settings

1.Temperature Setting: Refrigerator: 36°F (2°C). Freezer: -4°F (-20°C).

2.Temperature Display Scale: F.

b)Temperature Setpoint

The temperature setpoint is the value for the average cabinet temperature. The temperature differential for the compressor to turn on and off is ±3°F (±1.7°C) of the temperature setpoint. For example, for a refrigerator temperature setpoint of 36°F (2°C), the compressor comes on at 39°F (3.7°C), and the compressor goes off at 33°F (0.3°C). If necessary, adjust the temperature setpoint as follows:

1)Press and hold the upper or lower button briefly, then release. The current temperature setpoint flashes. Press the upper or lower button until the desired value is displayed. After a few seconds, the display returns to the current cabinet temperature and the temperature setpoint is saved.

•For refrigerators, the temperature setpoint is adjustable between 34°F and 52°F

(1°C and 11°C). Factory default is 36°F (2°C).

•For freezers, the temperature setpoint is adjustable between -15°F and +12°F

(‑26°C and -11°C). Factory default is -4°F (-20°C).

Note: Do not adjust the temperature setpoint outside of the factory-specified range. Adjustment outside of this range may prevent the unit from operating correctly.

c) Changing the Temperature Display Scale (F or C)

To change the temperature display scale, press the upper button for 5 seconds. The current setting is displayed. Press the upper button to change the scale. After a few seconds, the display returns to the current cabinet temperature and the setting is saved. The factory default is F.

Note: Pressing the upper and lower button at the same time for 5 seconds (or until "- - -" appears on the display module), turns the compressor, condenser fan motor, and evaporator fan motor (freezer) off. To turn the unit on again, press the upper and lower button together for 5 seconds until the cabinet temperature appears on the display module. CAUTION! The three dashes must be cleared, otherwise the compressor will not run and product will be lost.

d) Manual Defrost

Manual defrost may be initiated by pressing and holding the lower button for 5 seconds. "dEF" appears in the display. For further details, see "II.B.1. Sequence Cycles and Shutdown."
