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.
