Setting Temperature on Commercial Freezers or Fridges with Dixell Controllers

Static temperatures are the simplest way to ensure your fridges or freezers provide predictable cooling. You can set a static temperature in the following way:

1. Press the SET button and hold it until the temperature value starts blinking.
2. Use the UP or DOWN arrow buttons to increase or decrease the temperature to the desired number.
3. Press the SET button again to finalize your decision and lock in the temperature.

Setting the Temperature Difference With the “OT” Function

The “OT” function on the Dixell controller allows you to set a temperature difference between the outside and inside reader. For example, if you place your temperature difference to two, and the temperature reader shows 38 degrees, the inside temperature will be 36 degrees.

1. Press and hold the DOWN arrow and the SET button simultaneously.
2. Once this process starts, the monitor should read “nP”, but you must keep holding these buttons until the reading changes to “L2”.
3. Once you release, the monitor should read “HY”; do not panic. This reading is correct.
4. Press the UP arrow button until you see “OT” on the screen.
5. Press SET, and you should see a number. This number is the current temperature difference. The default is 0.
6. Use the UP or DOWN arrow buttons to increase or decrease the temperature difference to the desired number.
7. Press SET, and the monitor will flash and return you to the home screen.
8. Let the device idle, and it should return its temperature reading screen.
