VENTILATION THE RIGHT WAY
V E N T I L AT I O N & H E AT R E C O V E R Y
6 Connecting 2 to 5 ventilation units
Up to five 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 configuration
(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 gener-
ates 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 first ventila-
tion unit (master).
►
Connect “GND” to all the ventila-
tion units ( slaves).
