5.4 Teaching-in

Please read this entire section before starting the teach-in procedure.

First set up your Homematic IP Access Point via the Homematic IP app to enable operation of other Homematic IP devices within your system. For further information, please refer to the operating manual of the Access Point.

You can connect the device either to the Access Point or to the Homematic Central Control Unit CCU2. For detailed information, please refer to the Homematic IP User Guide, available for download in the download area of www.eQ-3.de.

To integrate the switch circuit board into your system and enable it to communicate with other Homematic IP devices, you must teach-in the device to your Homematic IP Access Point first.

To teach-in the switch circuit board, please proceed as follows:

• Open the Homematic IP app on your smartphone.
• Select the menu item "Teach-in device".
• After connecting the PCB to the power supply, the teach-in mode remains activated for 3 minutes.

You can manually start the teach-in mode for another 3 minutes by pressing the system button (B) shortly (see figure 4).

• Your device will automatically appear in the Homematic IP app.
• To confirm, please enter the last four digits of the device number (SGTIN) in your app or scan the QR code. Therefore, please see the sticker supplied or attached to the device.
• Please wait until teach-in is completed.
• If teaching-in was successful, the device LED (A) lights up green. The device is now ready for use.
• If the device LED lights up red, please try again.
• Please select, in which application (e.g. light or security) you would like to use the device.
• Allocate the device to a room and give the device a name.

6 Operation

After teaching-in, you can control the switch circuit board e.g. using a connected Homematic IP Remote Control or the Homematic IP app and switch connected devices on or off.

Simple operating functions are available also directly on the device:

- To trigger a function test or to switch the actuator on of off, press the system button (B) shortly. The device LED (A) indicates the switching state. The device LED lights up permanently as soon as the actuator is switched on.

7 Troubleshooting

7.1 Command not confirmed

If at least one receiver does not confirm a command, the device LED (A) lights up red at the end of the failed transmission process. The failed transmission may be caused by radio interference (see „1 Information about this manual“ on page 27). This may be caused by the following:

• Receiver cannot be reached.
• Receiver is unable to execute the command (load failure, mechanical blockade, etc.).
• Receiver is defective.

7.2 Duty cycle

The duty cycle is a legally regulated limit of the transmission time of devices in the 868 MHz range. The aim of this regulation is to safeguard the operation of all devices working in the 868 MHz range.

In the 868 MHz frequency range we use, the maximum transmission time of any device is 1% of an hour (i.e. 36 seconds in an hour). Devices must cease transmission when they reach the 1% limit until this time restriction comes to an end. Homematic IP devices are designed and produced with 100% conformity to this regulation. During normal operation, the duty cycle is not usually reached. However, repeated and radio-intensive teach-in processes mean that it may be reached in isolated instances during start-up or initial installation of a system. If the duty cycle is exceeded, this is indicated by three long flashes of the device LED (A), and may manifest itself in the device temporarily working incorrectly. The device starts working correctly again after a short period (max. 1 hour).

7.3 Error codes and flashing sequences

Flashing code	Meaning Solution
Short orange flashing	Radio transmission/attempting to transmit/data transmission	Wait until the transmission is completed.
1x long green lighting	Transmission confirmed	You can continue operation.
1x long red lighting	Transmission failed	Please try again (s. „7.1 Command not confirmed“ on page 38).
Short orange flashing (every 10 s)	Teach-in mode active	Please enter the last four numbers of the device serial number to confirm (see „5.4 Teaching-in“ on page 36).
1x long red lighting	Transmission failed or duty cycle limit is reached	Please try again (see sec. „7.1 Command not confirmed“ on page 38 or „7.2 Duty cycle“ on page 39).
6x long red flashing	Device defective	Please see your app for error message or contact your retailer.
1x orange and 1 x green lighting (after power supply is applied)	Test display Once	Once the test display has stopped, you can continue.

8 Restore factory settings

The factory settings of the device can be restored. If you do this, you will lose all your settings.

To restore the factory settings of the switch circuit board, please proceed as follows:

• Disconnect the switch circuit board from the power supply.
• Restore the power supply of the PCB while pressing the system button (B) and hold down the system button for 4 seconds (see fig. 4) until the LED (A) will quickly start flashing orange.

- Release the system button again. - Press and hold down the system button again for 4 seconds, until the status LED lights up green.

- Release the system button to finish the procedure. The device will perform a restart.

9 General information about radio operation

Radio transmission is performed on a non-exclusive transmission path, which means that there is a possibility of interference occurring. Interference can also be caused by switching operations, electrical motors or defective electrical devices.

The range of transmission within buildings can differ greatly from that available in the open air. Besides the transmitting power and the reception characteristics of the receiver, environmental factors such as humidity in the vicinity have an important role to play, as do on-site structural/screening conditions.

eQ-3 AG hereby declares that this device complies with the essential requirements and other relevant regulations of Directive 1999/5/EC. You can find the full declaration of conformity at www.eQ-3.de.
