B. Temperature
The default temperature scale is °F, but it can be changed to read °C. To change,
see "III.B.3. Changing the Temperature Display Scale (°F or °C)."
1. Default Temperature Settings
a) CPT Setpoint: 32°F (0°C).
b) CRES Setpoint: 35°F (2°C).
c) Temperature Display Scale: °F.
2. 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 temperature setpoint of 32°F (0°C), the
compressor comes on at 35°F (2°C), and the compressor goes off at 29°F (-2°C).
If necessary, adjust the temperature setpoint as follows:
1) Press and hold the up button briey, then release. The current temperature setpoint
appears.
2) Press the up or down button until the desired value is displayed. After a few sec., the
display returns to the current cabinet temperature and the temperature setpoint is
saved.
• The temperature setpoint is adjustable between 28°F and 45°F (-2°Cand 7°C).
The factory default is 32°F (0°C) for CPT and 35°F (2°C) for CRES.
NOTICE! Do not adjust the temperature setpoint more than 2°F (1°C) at a time.
Allow the temperature to stabilize for a minimum of 8 hrs. before making further
temperature setpoint adjustments.
3. Changing the Temperature Display Scale (°F or °C)
To change the temperature display scale, follow the steps below.
1) Press and hold both the up and down buttons for 5 sec. "PAS" appears briey in the
display, then "000" appears.
2) Press the up button to change the display to "001".
3) Press the SC button. "
EHE
" appears in the display. Press the up or down button until
"diS" is displayed.
4) Press the SC button. "CFu" appears in the display. Press the SC button again. The
current temperature display scale setting appears.
5) Press the up or down button to change the temperature display scale.
6) Press the SC button to save the setting. Wait 1 min. or press the manual defrost button
twice to return to the temperature display.
C. Manual Defrost
To initiate a manual defrost, press and release the manual defrost button. The defrost
icon and "dEF" appear in the display.
