The light-emitting diodes will ash when there is an alarm.
In this situation you can download the error code to the display
and cancel/sign for the alarm by giving the top knob a brief push.
Defrosting
A “-d-” is appears in the display during defrosting. This display will
appear for up to 15 minutes after cooling resumes.
However, the “-d-” display does not apply if:
- Temperature is reached within 15 minutes.
- Regulation is stopped via the “Main Switch”.
- A high temperature alarm is activated.
The buttons
When you want to change a setting, the upper and the lower
buttons will give you a higher or lower value depending on the
button you are pushing. But before you change the value, you
must have access to the menu. You obtain this by pushing the
upper button for a couple of seconds - you will then enter the col-
umn with parameter codes. Find the parameter code you want to
change and push the middle buttons until value for the parameter
is shown. When you have changed the value, save the new value
by once more pushing the middle button.
