On most digital controllers the safe, low-risk checks are:
Read the current cabinet temperature on the display and confirm it matches what you expect for the time of day.
Check the setpoint (SP) without changing it if possible (many controllers show SP via a short press of a set key or by entering a menu).
Confirm any active alarms (high temp, probe fault, door open) and note the time and reading for your HACCP record.
If you are changing a setpoint, do it in small steps (1°C at a time) and allow the freezer time to stabilise before changing again. If you are unsure which controller type your Unifrost upright has, use the model details to match the correct instructions via Unifrost Support.
