Dixell Digital Controls

Many Oscartek cases utilize an electronic control board with digital thermometer / thermostat, providing:
- Temperature accuracy.
- Programmable defrosting.
- Diagnostic capability (eliminating need for mechanical defrost clocks).
Temperature Setting
Please Note: These are Low Temp Control Setting Instructions for Oscartek Gelato & Ice Cream Showcases
To Check Temperature Setting:
- Press and hold in the set button for 5 seconds to see the temperature setting
- To adjust the temperature setting use the up or down arrow
- **normal setting is 4 degree F
- After checking or changing the temperature setting - press the set button
To Check All Parameters:
- Press and hold in the down arrow and set
- Button together for 5 seconds till you see HY – release both buttons
- Press the down arrow 1 time till you see PR2
- Press set and you will see PA5
- Press set and you will see a flashing zero
- Press the up arrow 3 times till you see 3
- Press set and you will see the 2nd flashing zero
- Press the up arrow 2 times till you see 2
- Press set and you will see the 3rd flashing zero
- Press the up arrow 1 time till you see 1
- Press set
You Will Now See HY:
- Press set and you will see the setting for HY
- To change a setting use up or down arrow
- Press set and you will see the next parameter
- Then press set to check that setting
- continue to press set one time to move to next parameter
- And then set again to check that parameter
From HY:
If you just want to check a certain parameter, use the up or down arrow till you see the one you want to check. Then press set to check that parameter.
After checking or changing the parameters – wait for 10 to 15 seconds and the control will reset and go back to reading the case temperature.
