7.4 Venting
program
As a result of pressing the key longer (8 - 13 sec.) a permanent air-extraction program of
approx. 4.5 minutes is started. The four light-emitting diodes light up as strip lighting in an
upwards and downwards direction and the program runs through the stages with different
rotation speeds and for different durations. The workflow can be terminated early by pressing
the key. The pump then returns into the operating mode previously selected.
7.5 Keyboard
lockout
After the pump has been adjusted, there is a possibility to switch on a keyboard lockout. As a
result of this, an unintentional re-adjustment of the pump is prevented. For switching on again,
the key must be held pressed for approx. 20 sec. After the key has been pressed the pumps
signal after 8 sec. by means of the strip lighting that they are in the air-extraction mode. If the
key is held pressed for a further 12 sec., all 4 LED's light up briefly. The pump indicates that the
keyboard lockout is activated. To deactivate it, hold the key pressed for so long until all LED's
light up briefly.

Installation
