With the SAVE / EXIT button to return back to the sub menu fan settings. Repeat this
procedure for the humidity setting. The third setting you can find the fan settings. Under
this sub menu, you get the following settings:
1. Minimum speed
2. Maximum speed
3. Negativepressure
Here you can set the minimum and maximum speed of the exhaust fan. These values will
never be exceeded in day and night mode and are always the same. The supply air fan
don't have a minimum speed value and will turn off when the temperature and humidity
undercuts the set value. By setting of the minimum speed value at the exhaust fan you
avoid odours escape through small openings in the room. By setting the maximum speed
value you avoid the fans making to much noise on full load. The third setting you have the
negative pressure, this setting reduces the intake fan speed according the value of the
exhaust fan speed and work synchrony together. For example: If we set a -20% negative
pressure, the exhaust air fan operates at full load 100%, the intake fan will have 80%. The
Exhaust fan removes more air from the room as the intake fan blows inside and you obtain
a guaranteed negative pressure during the regulation. If the exhaust fan runs at 50% then
the intake air fan runs at 40%. -20% of its power. You can see this current ratio in the main
