Maximum speed only (factory setting):
This can be accomplished with a cable bridge on de motor between
[10V]
and [E1]
or between
[T2]
and
[S3]
on the 6-pole connector. This will cause the fan to run at maximum speed permanently. This bridge
has been connected standard.
With a speed control (potential meter)
A 3-wire speed control (GA3955) or another potential meter can be connected to:
- connectors
[10V]
[GND]
and
[E1]
in de fan motor
- or to
GND[T1], 10V[T2]
and
0-10V IN[S3]
of the 6-pole connector.
Make sure that the potentiometer has a resistant value of 10kΩ.
0-10V External control
An external
0-10V
current can be put:
- on the connectors
[GND]
and
[E1]
in the fan motor
- or on
GND[T1]
and
0-10V IN[S3]
on the 6-pole connector
Multiple WWH’s on one control
Eigh WWH’s can be connected to 1 speed control.
The
10V[T2]
power supply may only be demanded from 1 WWH, the others should not be connected!
