st 

 

 

 

It may be useful to test run the fan at 
installation, adjustment of parameters and 
during troubleshooting. Follow the instructions 
below: 
 
In the status view, normal view, first press 

<Setup>

 and then <

> to get to the 

Service/System view. 
 
 
In the Service/System view press 

<Select>

 to 

mark the first row. Press <

> to scroll down to 

Diagnostics. Press 

<OK>

 to select this function. 

 
 
Select the unit to diagnose. If only one unit is 
connected, it is already marked, Press 

<OK>

 
 
 
 
 

Select ”Fan test”

 by pressing <

> from the 

initial diagnostics screen. Then press 

<Select>

 so 

that ”Fan test” is marked and confirm the 

selection by pressing 

<OK>

 
 
 
 
 
 
 
 
 
When the fan is tested, the entire sequence is 
tested by opening any motor dampers. The fan 
therefore starts with a set delay. This also 
applies if motor dampers are not connected.  
 
The view for the fan test looks a little different 
depending on the set fan type. If the system is 
instead set to fan type EC or AC fan, the fan 
speed can be adjusted up and down in 10 % 
increments using the 

<+>

 and 

<‐>

 buttons as 

seen in the image at the bottom right. If the 
system is instead set to CR, for relay control of 
the fan, the user can only start and stop the fan.
