First control level:

Adjusting the cold room setpoint and actual time

If none of the keys is pressed, the display indicates the actual value of the temperature and the
actual time. Pressing the SET key, the setpoint shows on the display.
If the setpoint is to be changed, the SET key is to be kept pressed while adjusting the setpoint with
the keys UP and DOWN.
Please note that the setpoint can only be changed within the set setpoint limits.
The time can be adjusted with the SET time key in the same way.

General reference

Note that the value is transferred to the captive memory and is safe also after power failure.
