Universal Functions
The universal functions section comprises of three buttons.
The button with the hand symbol allows switching between manual override or normal
operation of the schedule.
The LED next to the button with the leaf symbol indicates efficient operation when the leaf
is green and turns red when operation is not optimal. The button will return the fume hood
to energy efficient operation.
The button with the light bulb turns the fume hood light on or off.

Note
The device is protected against faulty wiring but communications will not work on interchanged
wires.
Commissioning KNX
When only one device is connected to the KNX PL-Link bus, the operator display panel
automatically establishes communications with the Fume hood controller , from where the
functions are downloaded to the room operator unit (plug & play).
Addressing:
1. Short press the programming pin (<0.5 sec).
The device goes into programming mode; the service LED is continuously on.
The tool identifies the current operator display panel that is operated and assigns it.
2. After the device is commissioned, deactivate the programming mode by shortly
pressing the programming pin (<0.5 s). The service LED goes off.
Note: Programming mode resets to “disabled” each time the device restarts.
Factory reset:
1. Long press the programming pin (>20 s). The device is locked and reboots within 10
seconds. The Fume hood controller deletes it from its device list. During this time, it is
safe to remove the device from the network.
If the bus plug remains connected, the device acts like a newly inserted device
requiring again automated or manual configuration.
Note: This operation resets all user preference data and configuration settings to factory
default. This operation is irreversible.
