How do I change the temperature setpoint on a commercial upright freezer digital controller?

Because Unifrost uprights can ship with different digital controllers (commonly Dixell, Elitech or Carel), the exact button names can vary. Use this safe, owner-level method:

Check what the display is showing: most controllers show air probe temperature, not product core temperature.

Enter setpoint view: on many controllers you press and hold SET for 1–3 seconds until the setpoint value appears.

Adjust: use ▲/▼ to raise or lower the setpoint.

Save and exit: press SET again (or wait ~5–10 seconds) for it to store.

Owner tip: if you cannot change the value (it jumps back, or buttons seem locked), don’t force it. Some units are keypad-locked or restricted to prevent accidental parameter changes. In that case, record the controller make/model and follow the correct PDF for that controller or contact support before changing deeper parameters.
