   The temperature setpoint is the value for the cabinet temperature. The temperature differential for the heater(s) to turn on or off is ±1.5°F (±0.8°C) of the temperature setpoint.
   For example, the temperature setpoint of 150°F (65.5°C), the heater(s) come on at 148.5°F (64.7°C) and the heater(s) go off at 151.5°F (66.3°C). If necessary, adjust the temperature setpoint as follows:

1. To change the temperature setpoint, press and release the “P” button or the up or down button. The current temperature setpoint appears. Press the up or down 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.
   • Heated Holding Cabinet temperature setpoint is adjustable between 80°F and 180°F (26.6°C and 82.2°C). The factory default is 150°F (65°C).

3. Changing the Temperature Display Scale (°F or °C)
   There are 4 temperature display settings from which to choose.
   The factory temperature display default is F0 for °F whole number.
   For a whole number temperature display scale value, select F0 or C0.
   For a temperature display scale value to one decimal point, select F1 or C1.

To change the temperature display setting, follow the steps below.

1. Press the “U” and “P” buttons together for 5 seconds. I.uP is displayed.
2. Press the “P” button. The current display setting (F0, F1, C0, or C1) and I.uP start flashing.
3. Press the up or down button until the desired temperature display setting appears.
4. Press the “P” button to save the selection. I.uP is displayed. To return to normal display mode, press and hold the “U” button for 5 sec. Display returns to normal display mode.
   If no other button is pressed after pressing the “P” button, 25 sec. later, display returns to normal display mode.
