1 Safety instructions
To avoid potential damage, read and follow the following instructions:
Electrical devices may be mounted and connected only by electrically skilled persons.
Danger of electric shock. During installation and cable routing, comply with the regulations and standards which apply for SELV circuits.
Danger of electric shock. Make sure during the installation that there is always sufficient insulation between the mains voltage and the bus. A minimum distance of at least 4mm must be maintained between bus conductors and mains voltage cores.
Danger of electric shock on the installation. Do not connect any external voltage to the inputs. The device might be damaged, and the SELV potential on the bus line will no longer be available.
This manual is an integral part of the product, and must remain with the customer.
2 System information
This device is a product of the KNX system and complies with the KNX directives. Detailed technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The function of this device depends upon the software. Detailed information on loadable software and attainable functionality as well as the software itself can be obtained from the manufacturer's product database.
The device can be updated. Firmware can be easily updated with the STEINEL KNX Service App (additional software).
The device is KNX Data Secure capable. KNX Data Secure offers protection against manipulation in building automation and can be configured in the ETS project. Detailed technical knowledge is required. A device certificate, which is attached to the device, is required for safe commissioning. During mounting, the device certificate must be removed from the device and stored securely.
Planning, installation and commissioning of the device are carried out with the aid of the ETS, version 5.7.7 and higher or 6.1.0.

5 Mounting and electrical connection
Mount device
In secure operation (preconditions):
- Secure commissioning is activated in the ETS.
- Device certificate entered/scanned or added to the ETS project. A high resolution camera should be used to scan the QR code.
- Document all passwords and keep them safe.
-
In secure operation: device certificate must be removed from the device and stored securely.
-
Mounting in suitable appliance box. Observe cable routing and spacing.
Bus connection
- Connect bus with a KNX device connection terminal to KNX connection (1) (see figure 1).

Installation instructions
- To avoid interference from EMC radiation, the cables of the inputs should not run parallel to cables carrying mains voltage or to load cables.
- The voltage potentials of the connecting cables for the inputs and outputs are not galvanically isolated from the bus voltage.
The connecting cables actually lengthen the bus cable. The specification for the bus cable length (max. 1000m ) must be observed.
- Do not connect the COM connections of multiple push-button interfaces.
- No series resistance required for the connection of LEDs.
- Use channels 1 and 2 for NTC temperature sensors. Select a compatible NTC temperature sensor based on the characteristic curve of the NTC (see tables below).

DANGER!
Danger of electrical shock when mains voltage 230 V or other external voltages are connected!
Electric shocks can be fatal.
Device may be destroyed.
Only connect potential-free push Buttons, switches or contacts.
- Connect push Buttons, switches, contacts, LED or NTC to enclosed connecting cables (4) according to the connection examples; (see figure 3) to (see figure 6). The connection examples show the use with inputs and outputs.

6 Commissioning
Programming the physical address and application program
Switch on the bus voltage.
Press the programming button (2). The programming LED (3) lights up.
- Program the physical address with the ETS. The programming LED goes out.
■ Program the application program with the ETS.
6.1 Safe-state mode and master reset
Safe-state mode
The safe-state mode stops the execution of the loaded application program.
i Only the system software of the device is still functional. ETS diagnosis functions and programming of the device are possible.
Activating safe-state mode
- Switch off the bus voltage or remove the KNX device connection terminal
Wait approx. 10 seconds.
Press and hold down the programming button. - Switch on the bus voltage or attach the KNX device connection terminal.
Wait until the programming LED flashes slowly. - Release the programming button.
The safe-state mode is activated.
By briefly pressing the programming button again, the programming mode can also be switched on and off in the safe-state mode as usual. If the programming mode is active, the programming LED stops flashing.
Deactivating safe-state mode
- Switch off bus voltage (wait approx. 10 seconds) or carry out ETS programming.
Master reset
The master reset restores the basic device settings (physical address 15.15.255, firmware remains in place). The device must then be recommissioned with the ETS.
In secure operation: A master reset deactivates device security. The device can then be recommissioned with the device certificate.
Performing a master reset
Precondition: The safe-state mode is activated.
- Press and hold down the programming button for >5 s. The programming LED flashes quickly.
- Release the programming button. The device performs a master reset, restarts and is ready for operation again after approx. 5 s.
Restoring the device to factory settings
The device can be reset to factory settings with the STEINEL KNX Service App. This function uses the firmware contained in the device that was active at the time of delivery (delivered state). Restoring the factory settings causes the device to lose its physical address and configuration.
