d0: Defrost interval
The "defrost interval" defines the time after which defrosting is initiated.
After each defrost start, this time is reset and processed again.
In the event that no defrosting is wanted, the defrost can be deactivated
through the parameter setting d0 = 0. Then only manual defrosting is
possible via the UP key.
d3: Defrost time limit
The defrosting operation cannot take longer than the time set here. When
this time is exceeded, the defrosting ends.
By setting d3 = 0, the time monitoring is inactive.
7.3 Third control level (A parameter)
Setting of control parameters
The third control level is accessible by first entering the second level, and
then scrolling up the parameter list till the highest parameter. Then, press
only the UP key for at least 10 seconds. The message „PA“ will be shown
in the display.
By then pressing the UP and DOWN keys simultaneously for at least
4 seconds, the parameter list for the third control level is reached
(beginning with A1).
With the UP key the list can be scrolled up and with the DOWN key,
downwards.
If one presses the SET key, the value of the respective parameter is
displayed and by then further pressing the UP or DOWN keys, the value
is adjusted.
After releasing all the keys, the new value will be stored permanently. If,
during 60 seconds, no key is pressed, there is an automatic return to the
initial position.
