If a timer is not set, the timer is always counted upward. The
arrow "up" is inserted.
1. Activate the timing display with the aid of the selection window by using the rotary
pushbutton controller Hei-GUIDE (9).

The value can therefore be adjusted. A time between 1 and 999 minutes can be se-
lected by turning the Hei-GUIDE (9).
3. Turn the rotary pushbutton controller Hei-GUIDE (9) to set the display value to the
desired timing value.
4. Pressing the Hei-GUIDE (9) again takes over the selected new value. The evapora-
tor responds immediately and the time is counted backward.
