This product must be secured with a miniature circuit breaker (MCB) of max. 16 A in the electrical cabinet.
The MCB rating is limited by national installation rules.
* Classical push buttons (e.g. 170-0000x) can be connected to the extension terminals. All mechanical push-button extensions wired to the same terminal, will show the same behaviour (either the standard behaviour of the actor or a programmed behaviour). It is not possible to configure the behaviour of these extension switches separately. The maximum total wire length for all extension buttons connected to the Zigbee® dimmer is 50 m. It is not possible to add a LED lighting unit to the extension buttons.
Zigbee® network
Network setup
Follow the Zigbee® network setup advice below to guarantee the meshing of the devices before installing the switch on the wall.
More information on Zigbee® network principles: guide.niko.eu
* Also, respect a minimum distance of 2 m between a Zigbee® device (including the smart hub) and another RF transmitter (for example a Wi-Fi device) or devices such as motors, pumps, electronic LED transformers, solar panel inverters, home battery storage …

Stand-alone use
All 230 V connected devices for Niko Home Control for traditional wiring can be used in stand-alone mode until they are connected to a wireless smart hub (552-00001) or wireless bridge (550-00640). In stand-alone mode, they switch their own contact. Mechanical push-button extensions that are wired to the extension terminal can also be used in stand-alone mode.
Connected use
1. Connected to a Niko Home Control installation
More advanced functionalities become available if you connect this device to your wireless smart hub (552-00001) or wireless bridge (550-00640) using the Niko Home Control programming software or Niko Home app. Consult guide.niko.eu for more information about the installation and the connected use.

How to connect the Niko device to the Niko Home Control network
- Reset the Niko Zigbee® device when it is already connected to another network. See § Reset.
- Follow the onboarding procedure in the Niko Home Control programming software or the Niko Home app to add new Niko Zigbee® devices.
- Set the Niko Zigbee® device in pairing mode by pressing the switch button 3 x within a period of 6 seconds > See image § Pairing mode. The blue LEDs start blinking for max. 5 minutes.
- The connected double switch is successfully added to the Zigbee® network when the blue LEDs are ON for 4 seconds.
2. Connected to a third-party Zigbee® network
Niko connected Zigbee® devices behave like standard Zigbee® devices in third-party networks that allow this operation. Consult the manufacturer’s manual for more information on the possibility to use third-party Zigbee® devices in their network.
Specific Niko Home Control functions will not be enabled with Niko Zigbee® devices connected to a third-party Zigbee® controller/gateway.
Consult the details on guide.niko.eu. See also the disclaimer on www.niko.eu/zigbee.

Troubleshooting
| Problem | Cause | Action |
| I want to use the connected switch, but I don’t yet have a smart hub or wireless bridge to connect it with | All 230 V connected devices for Niko Home Control can be used in stand-alone mode until they are connected to a smart hub or wireless bridge. In this mode, they only switch their own contact. Extension switches that are wired to the connected switch can also be used in stand-alone mode | |
| My smart hub or wireless bridge doesn’t work anymore | Consult the manuals of the wireless smart hub (552-00001) or wireless bridge 550-00640) at www.niko.eu | If the power of the smart hub or wireless bridge switches off, all 230 V connected devices will continue to operate in standalone mode. They will only switch or dim their own contact. Consult the respective product manuals to resolve the issue |
| The connected switch cannot be found in the Niko Home app or programming software | The power supply is off | Switch on the power supply |
| The distance between the connected switch and the smart hub or wireless bridge is too small | Make sure there is a distance of at least 2 meters between the device and the smart hub or wireless bridge | |
| The distance between the connected switch and the smart hub, wireless bridge or another connected device is too big | Make sure there is a distance of maximum 10 meters between the device and the smart hub, wireless bridge or a subsequent 230 V connected Zigbee® device. To increase the range, add, for example, an additional smart socket outlet or Zigbee® extender to the network | |
| There is no connection between the Niko Home app or laptop/pc and the smart hub or wireless bridge | Check the connection to the smart hub or wireless bridge. Consult the respective product manuals to resolve the issue | |
| The load does not switch on | The miniature circuit breaker (MCB) of the lighting circuit is disabled or there is a short circuit | Check whether the lamp complies with the load specifications described in this manual |
| The switch is defective | Replace the switch | |
| The lamp is defective | Replace the lamp | |
| The lamp does not switch off completely and displays an afterglow | The cabling is too long, which creates capacitive effects with leakage currents. Or you’re switching a low wattage lamp that is sensitive to leakage currents | Install one or more LED compensators (310-05001) over the switched phase and the neutral wire |
LED behaviour
| Each channel (up and down) has its own LED that provides feedback when in normal operation. In case of a special status (blue or red feedback), the LEDs from both channels will light up | |||
| LED off |  |
Normal operation when:
|
Enable/disable the white LEDs:
|
| The connected double switch is not powered | Check the wiring and the miniature circuit breaker (MCB) in the electrical cabinet | ||
| The connected double switch is malfunctioning | Replace the connected double switch if the actions recommended above did not resolve the issue | ||
| White LED continuously on |  |
Normal operation when the connected double switch is switched ON and is used with LED feedback | The connected double switch is working fine |
| Red LED is flashing |  |
The connection to the smart hub or wireless bridge is temporarily interrupted | The connection will restore automatically. If it doesn’t, please try power cycling your smart hub or wireless bridge and check if the connected double switch is still within the range of the smart hub or wireless bridge. Check guide.niko.eu for more information |
| Blue LEDs are flashing |  |
The connected double switch is trying to connect to the Zigbee® network | Wait until the LEDs stop flashing |
| Blue LEDs are on for 4 seconds |  |
The connected double switch is connected to the Zigbee® network | The blue LEDs will switch OFF after 4 seconds. The connected double switch is ready to be used |
