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 device offers plug & play functionality.
●The device receives its power from the connected room automation station via the KNX
PL-Link interface, or from the jack connector.
●Engineering and commissioning using the ABT (Automation Building Tool) tool and SSA
(Setup & Service Assistant) tool.
Mounting
●The devices are suitable for wall mounting and panel mounting.
●Recommended height: 1.50 m above the 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 if any, as air currents can affect sensor
readings.
●Adhere to allowed ambient conditions.

Installation
CAUTION
The devices are not protected against accidental connection to AC 230 V.
●Use the correct cables for the KNX PL-Link bus.
●Do not interchange the wires of the KNX PL-Link cable.
●Observe all local installation regulations.
Commissioning
Prerequisites
Before commissioning the device, make sure an application is downloaded into the
connected controller, from where the functions are downloaded in the device.
Download the application using SSA-DNT (Pack & Go) or ABT.
For this purpose (or for service), connect ABT to the controller via USB or Ethernet.
Automatic commissioning
When connected to the KNX PL-Link bus, the device automatically communicates with the
connected controller. The following routine is executed.
Step With display Description
1Build number and version of the device are displayed.
2The individual address (IA) is downloaded into the
device via KNX PL-Link.
This step is skipped if the device is already configured.
Note: The configuration file can be downloaded any
time; as a result, these characters are displayed every
time the controller initializes download.
3After startup, the device displays a normal operation
page.
(The operation page displayed on the left side is a
sample view; the view depends on the application
selected on the controller.)
3b When the configuration is faulty, "Unconfigured" is
displayed along with the temperature measured by the
local temperature sensor.
In this case, manual commissioning must be performed
(see below).

Manual commissioning
When automatic commissioning fails or when multiple devices are connected, manually
commission the device as follows:
Addressing
1. Connect SSA-DNT or ABT to the controller and activate the online commissioning
function.
2. Load web page "KNX PL-Link identification".
Activate the identification function.
aThe controller now waits for a signal from the device.
3. On the device, simultaneously press buttons 1 and 8 for at least 5 seconds.
aThe "Engineering" page is displayed.
4. Press button 2.
aThe display changes from "DISABLE" to "ENABLE".
aThe tool identifies the currently active-device and assigns it.
5. After the device is commissioned, change from programming mode to “DISABLE” by
pressing button 2.
Connection test
1. Press button 3 to test the KNX PL-Link connection.
aThe display shows the result of the connection test ("DONE" or "FAIL").
2. Press button 8 to return to the engineering page.
Reset to factory settings
NOTICE
This operation resets all user
-
defined data and configuration settings to factory default
This operation is irreversible.

Press button 4. The device is locked and reboots within 10 seconds. The controller removes
the device from its device list. During this time, the device can safely be removed from the
network.
If the bus plug remains connected, the device acts like a newly inserted device requiring
automated or manual configuration.
Programming pin and service LED
The devices come with a programming pin and a red service LED on the rear.
Addressing
1. Briefly press the programming pin (<0.5 s).
aThe device enters the programming mode; the service LED is continuously on. The
tool identifies the currently active device and assigns it.
2. After the device is commissioned, deactivate programming mode by shortly pressing the
programming pin (0.5 s). The service LED goes off.
Note: Programming mode returns to “disabled” each time the device restarts.
Connection test
1. Press the programming pin (>2s and <20s) to test the KNX PL-Link connection. After
releasing the programming pin, testing of the KNX PL-Link connection starts; the service
LED flashes (1/4s on, 7/4s off).
After approximately 10s, the test result is displayed:
- If the test is positive, the LED is lit continuously.
- If the test fails, the LED flashes (1s on, 1s off).
2. Briefly press the programming pin (<0.5s) to stop displaying the result of the connection
test. The service LED goes off.

Reset to factory setting
Press the programming pin (> 20s). The device is locked and reboots within 10 seconds. The
room automation station removes it from its device list. During this time, the device can
safely be removed from the network.
NOTICE! The LED is off during this procedure.
If the bus plug remains connected, the device acts like a newly inserted device requiring
automated or manual configuration.
NOTICE
This operation resets all user
-
defined data and configuration settings to factory default.
This operation is irreversible.
Operation
The button response is defined as follows:
●Pressing a button: 0.05 s ≤t ≤1 s
●Extended pressure: 3 s ≤t ≤5 s
●Constant pressure: 7 s ≤t
●Button combination: Press multiple buttons simultaneously
Maintenance
The device can be cleaned with commercial, solvent-free cleaning agents.
Do not use mechanical aids (rough sponge or similar materials) – only a soft, damp cloth.
Disposal
The device is considered an electronics device for disposal in terms of European
Directive 2012/19/EU and may not be disposed of as domestic garbage.
●Dispose of the device through channels provided for this purpose.
●Comply with all local and currently applicable laws and regulations.
Warranty
Technical data on specific applications is valid only together with Siemens products listed in
"Equipment combinations". Siemens rejects any and all warranties in the event that third-
party products are used.
