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

In most Unifrost upright freezer controllers, setpoint changes follow the same safe workflow:

Confirm the target: for frozen storage, aim for -18°C or colder (then validate with a separate probe in product, not just the display).

Check for a keypad lock: if buttons do nothing or you see a lock indicator, the controller may be locked. Use your model’s owner guide to unlock it before changing settings.

Enter setpoint mode: press and hold the SET key (or the setpoint key) until the setpoint value appears.

Adjust using ▲/▼, then press SET again to save.

Let the cabinet stabilise: avoid judging performance in the first hour after changes. Recheck temperatures over a normal service period and confirm with your HACCP checks.

If your controller menu labels differ, use the Unifrost “Owner Basics Guide” and the model-specific notes in Unifrost Manuals & Downloads rather than guessing menu items.
