1 Terminal block for pushbuttons
2 Terminal block for LEDs
3 Smiley on the side of the ter-

minal block for LEDs

NOTE

► Use the smiley (item 3 in Fig. 3)

as an orientation guide. It is
only in this position that the

6 Connecting 2 to 5 ventilation units

UptoveventilationunitscanbecontrolledwithoneInControlpushbuttonsensor.Thefollowing

conditions must be met:

— The ventilation units must all be of the same type.

— All the ventilation units that are connected to the same InControl pushbutton sensor should

be located in the same room.

— Ifpossible,thecontrolcablesshouldbearrangedandconnectedinastarconguration

(see Fig. 8) from the ventilation units to the InControl pushbutton sensor.

— The cable between the ventilation unit and InControl pushbutton sensor should be no more

than 15 m long.

— Ventilation unit 1 (master) must

always be switched on. It gener­ates the feedback for the LED on
the InControl pushbutton sensor.
Ventilation units 2 to 5 (slaves) only
respond to switching commands
from the InControl sensor.

NOTE

► Connect“+”onlytotherstventila-

tion unit (master).

► Connect “GND” to all the ventila-

tion units (master + slaves).
