10. The operation method of fan controller
Through the fan controller switch in the electric box, the air volume of this unit can be continuously
adjusted.
It is unnecessary to adjust air volume through the duct side wind level (unit outside static adjustment).
The air volume set should be in the operation air volume range.
Figure I shows the position of fan controller in the electric box and operation method.
After finishing the electric work, perform test run. According to the main points in Figure II making the
chosen switch No. accordant. And confirm if it reaches the needed air volume.
Note:
1) When operating the fan controller, it is possible to touch the electric charging part, so do cut off the
power supply.
2) Do not set the dial at the position less than 1.
3) The figure circled in Figure II indicate the capacity number of fan controller. The non-listed capacity
number may exceed the permitted operation capacity range, so it is impossible to operate.
4) When delivering from factory, the capacity number of fan controller is set at ìNo.5î.
Rotate this switch
(capacity number
setting:
No. 1 ~ No. 8)
Once the fan controller
has trouble, this linker
can perform emergency
assistant control. When
this linker is connected
to the linker from the
PCB, it can operate with
total load.
When this linker is
connected to the linker
from the PCB, through
the fan speed adjustment
panel to adjust speed.

as working condition point, according to Figure II ìThe characteristic chart of air volumeî, the capacity number
of fan controller is No. 2.
2) If the unit is in low speed operation, needing take outer static pressure is 60Pa in capacity air volume 32m

working condition point, according to Figure II ìThe characteristic chart of air volumeî, the capacity number
of fan controller is No. 4.
