How do I adjust the temperature set point on a Unifrost upright freezer’s digital controller?

Most Unifrost upright freezers use a similar digital controller layout. The usual method is:

Press and hold SET until the set point value appears (often it flashes).

Use ▲ / ▼ to change the set point.

Press SET again to confirm, or wait a few seconds for it to save automatically.

Tips that prevent callouts:

Make changes in small steps (for example 1°C at a time) and reassess after the cabinet stabilises.

If buttons do nothing, look for a keypad lock feature. Unlocking is commonly done by holding a key combination (varies by controller version), so refer to the model’s controller guide or manual if you are unsure.
