Hoping someone can clear this up for me as I have been scratching my head for a couple of hours now trying different configurations to get what I am after.
Pretty basic set up with some extract grilles connected to an inline fan which discharges out an external louvre.
As you can see the system inspector works so in theory everything is connected correctly. The problem I am having is when it comes to scheduling the system is double counting the external louvre flow rate and in the case above is reporting the fan is doing 1418 l/s not 709 l/s.
The way I have the connectors at the moment is E3 grille is set to preset and out, the intake on the fan is set to calculated and in, the outlet of the fan is set to preset and out, then the external louvre (which is an air terminal) is set to calculated and in. They are all using shared parameters.
Here is the system browser for the E10.
Should the louvre be something other than an air terminal? Should the fan connectors be linked or unlinked?
Looking forward to reading your responses ๐

Your exhaust terminal E3 needs to be
Preset
Out
Exhaust air
Specific Loss
The connection going into the fan neeeds to be
Calculated
In

The connection going out of the fan neeeds to be

Do not link connectors
Which looks like you have that correct.
I think the problem is with the louver. You don't want a closed system. You need an open end. Check the direction of air flow. I believe that one should be
Calculated
In
Hope that gets you closer.
Thanks but the only way I could get the fan not to double up is to have two different systems. So return from the grille to the fan then extract from the fan to the louvre. But that does still give 2 values on the fan, the right flow rate just for both the differnt systems.
