VENT DOORS
The vent doors' operation is based on the static pressure level in the room.
They respectively open or close when the pressure exceeds the high or low
pressure set points. In addition, different opening and closing set points
can be defined based on the outside temperature.
In minimum ventilation, the vent doors open during a pre-opening delay
before the activation of stage 1 fans. The same delay is used to close the
vent doors when stage 1 fans return to a stop.
The user can also define a stage level above which the vent doors always
remain closed.
Static Pressure Alarm:
Alarms can be set off if the static pressure level exceeds the user-defined
pressure limits. Refer to Alarm chapter to set the pressure limits.
Note that the vent door parameters are only accessible if a static
pressure sensor is enabled. Otherwise, the parameters shown in
this menu are replaced by the air inlet settings.
