Notes

Security

CAUTION

National safety regulations

Failure to comply with national safety regulations may result in personal injury and property

damage.

●Observe national provisions and comply with the appropriate safety regulations.

Engineering

●The room operator units offer plug & play functionality.

●The room operator units receive power from the connected room automation station via

the KNX PL-Link interface.

●KNX PL-Link supports plug & play functionality for pre-configured devices

●For KNX PL-Link wiring (topology, allowed cables and cable length), see the Desigo

installation guide, CM111043.

●Only electrical installers may install the base plate and the KNX PL-Link plug.

●Use the tear-off label with the barcode on the packaging / display and stick it on the floor

plan to prepare commissioning for several room operator units per room automation

station.

The same barcode label with unique identifier is available on the device.

Mounting and installation

Mounting

●The devices are suitable for wall and flush mounting with conduit box.

●Recommended height: 1.50 m above floor.

●Do not mount the devices in recesses, shelves, behind curtains or doors, or above or

near heat sources.

●Avoid direct solar radiation and drafts.

●Seal the conduit box or the installation tube, as air currents can affect sensor readings.

●Adhere to allowed ambient conditions.

●Mounting instruction A6V11521631 is enclosed with the devices.

Installation

●For KNX PL-Link wiring (topology, allowed cables and cable length), see the Desigo TRA

installation guide, A6V10361918.

●Use the correct cables for the KNX PL-Link bus

Manual commissioning (KNX PL-Link)

All commissioning work is done via the room automation station, using SSA-DNT or ABT.

ABT is never connected directly to a room operator unit.

When more than one QMX3.P... room operator unit is on the same trunk of the KNX PL-Link

bus, manual commissioning is as follows:

1. Connect SSA-DNT or ABT to the room automation station and activate the online

commissioning function.

2. Load web page “KNX PL-Link identification”.

Activate the identification function.

The room automation station now waits for a signal from the room operator unit.

3. On the room operator unit, enter Engineering mode:

–For unconfigured units, press the blank space on the bottom right corner for at least

5 seconds;

–For QMX3.P35H…, press for at least 5 seconds;

–For QMX3.P38H…, press for at least 5 seconds

4. The “Engineering” page is displayed.

5. Press “Program”.

The display changes from “Off” to “On”.

The tool identifies the current room operator unit that is operated and assigns an

address.

6. After the device is commissioned, the display automatically changes to “Off”.
