In case you forget to confirm the changes the LCD display returns to the main
screen after 2min. without saving. Go to the next setting with the DOWN button.
Temperature hysteresis setting.
This means the fan starts to work at >25C° room temperature and reaches the
maximum speed +2C° hysteresis at 27C°. In this 2C° hysteresis from 25C°27C°
the fan is running faster and slower depending on the measured temperature.
To change the value use again SET/SAVE button to enter the setting, change
the Value with UP/DOWN button and save and return to the selection with
SET/SAVE again.

What is hysteresis? Hysteresis
is the value between the lowest
and the highest point of the
regulation. Example: if we set
25C° and have a hysteresis of
2C°.
With the DOWN button you go
to the next setting "humidity
setting day time"repeat again,
enter the settings with
SET/SAVE or go to the next
setting with the DOWN button
Hysteresis setting for the
humidity day time, as described
above the hysteresis for
temperature you can change
here the controlling range for the
humidity value. For example:
10%rh at 60% humidity the fan
starts to work at 60% humidity
and +10%rh at 70%rh it reaches
its maximum speed.
Minimum speed setting day time.
Here you can choose the
minimum speed of the ventilator
which never should be undercut.

On the down left side speed bar you can see the actual setting for each filled
segment is 10% fan speed. Change the settings again with SET/SAVE as
described above.
Maximum speed setting day time. Here you can choose the maximum speed
setting of the ventilator which never should be exceeded. On the top left side
you can see the actual missing empty segments each is 10% fan speed.
Change the settings again with SET/SAVE as described above. Repeat all 6
settings we explained for day time now you can give the night time values of the
fan.
After you have gone through the 6 night time settings in the menu, you can set
the light level switch value of the light sensor.

You see the alternate blinking of
sun and moon segments. Enter
SET/SAVE to change the switch
level value between day and
night time. The lower the value,
as less light it needs to change
from day to night time mode.
This last setting is the switch
over time between day and night
mode. This is used to avoid an
immediate switching between
day and night mode.
If the light sensor reaches the
switching level a count down
starts according to the value in
seconds you are entering here.
As the countdown ends without
getting a light interrupt at the light
sensor the controller will switch
from night to day time or reverse
from day to night time. Enter
SET/SAVE to change the
values.
The Power LED indicates the
state of the fan. Blinking means
initializing the fan. Constant
shining at day time or short blink
at night time means the fan is ON
and running.
