Closing vent doors in tunnel ventilation:
Both
vent door outputs close when the controller
enters in tunnel ventilation. Refer to section
6.3.2.2 to select the tunnel fan output that
asks for vent doors to close.
* Seasonal Pressure Set Points:
High and low pressure set points can auto-
matically be adjusted according to the outside
temperature. Using higher pressure set points
during winter allows reducing the cold air
intake: the pressure level must be greater
before the curtain can start opening. In sum-
mer, the pressure set points are decreased
so that the curtain can open and close with
fewer restrictions.

The pressure set points are automatically ad-
justed according to the outside temperature.
The following graphic illustrates how they are
calculated. Seasonal changes are signalled by
user-defined outside temperatures (sec. 5.3).

2. Set the following parameters:
Static pressure Set Points:
Low/High Pressure Limits —
Set the static
pressure level below/above which the side-
wall vent opens and closes. If the outside
temperature probe is used, set these limits
separately for winter and summer. *
Seasonal
pressure set points are accessible if the outside
temperature probe is enabled (sec. 4.5.1).
Wind Effect Delay —
When the pressure level
exceeds the high or low pressure set points,
the sidewall vent starts opening or closing
continuously right after the wind delay has
elapsed. The high or low pressure condition
must thus be maintained over this delay for
the sidewall vent to start moving. This way,
the vent will not open or close needlessly
when wind drafts are causing fleeting varia-
tions in the pressure level. Set the wind effect
delay to the desired value.
Pre-opening Delay —
Select during how
much time the controller must open the
sidewall vent before activating minimum
ventilation fans. This delay ranges from 0 to
30 seconds.
