Qbus wireless Zigbee relay
- Zigbee wireless connection: Wirelessly connects to the Qbus system via the QWI/ZB interface (sold separately)
- Smart wireless switching for lighting and small power loads
- Easily fits into standard wall boxes
- Perfect for expanding existing installations
- State recovery after power failure: resumes to last relay position
The QWZ-REL02/230 is a dual relay module with wireless control via the Zigbee protocol. Thanks to the wireless relay, you can implement a Qbus system even in a traditionally wired installation. This module can switch small loads such as lighting devices.
Frequently Asked Questions
-
How do you read an existing configuration?
This is a completely different procedure depending on the type of controller.
- For the CTD controllers this goes as follows:
In the SMIII via "File" or "Utilities / Setup / SD card", click on "Recover QDB from SD".
After confirmation you choose the name and location where the file should be saved. The zipped QDB file is then read from the SD card of the CTD and saved. With a positive answer to the question "Unzip and open restored QDB?", All data will then be immediately available. If the data you were still working on was not sent or saved, you will first receive a notification to do so.
- For a CTL controller follow the following procedure:
Because this controller does not yet have a large memory, only limited data can be recovered. Ao the names are abbreviated to 12 characters and serial numbers are not stored anywhere.
The first step is therefore to type in ALL serial numbers via SMII via "File / Modules". These 6-digit serial numbers can be found on every module (DIN rail, switch, detector, etc.). For the SWC0x switches, an extra option was provided to have them send their serial number via “Search for modules”.
When you then click on the "down arrow", you can read all this limited information.
-
Always use the latest software for configuration.
It is always recommended to use the most recent version. This version supports the newest modules and resolves all known bugs.
If, for example, you enter a serial number and the correct module information does not appear, you are likely not working with the most recent software.
A newer version will always be able to open the older files (.QDB) without data loss.
The latest version of the System Manager software, along with the user manual and version history, can be found in the knowledge center.

Function description
The QWZ-REL02/230 is part of Qbus's wireless range. This means you can implement a Qbus system in a traditionally wired installation. The QWZ-REL02/230 is a dual relay module with wireless control via the Zigbee protocol. The QWZ-REL02/230 can be installed in a standard flush-mount box and is designed to be mounted close to the push buttons. This module is capable of switching small loads such as lighting devices.
Once the QWZ-REL02/230 is added to SMIII via its unique serial number, it can be linked to the Qbus Wireless Interface with Zigbee protocol (QWI/ZB) using the built-in push button. A green LED is provided to display the configuration status. Additionally, the relays can also be directly operated via 1 or 2 connected push buttons under power. The two relay contacts directly switch the connected voltage to the connected user(s).
If a voltage-free contact is desired or a heavy load needs to be switched, an additional relay/contactor must be provided, which is energized by this module. Therefore, the inputs are always linked to the two relay outputs. The inputs cannot be used for activating scenes or modes other than those compatible with relay outputs.
Thanks to the connection with the Qbus controller via the QWI/ZB, numerous applications and configurations are possible. This enables the use of various control options within the Qbus system, as well as online with, for example, Qbus Control.
The Zigbee relay can function with directly connected push buttons before it is linked to the QWI/ZB, but will then only support a bistable function. Also, when the module is outside the range of the Zigbee network, it will only support a bistable function.

- The module must not be opened. The warranty is void if the module is opened!
- Do not connect higher power capacities! Adhere to the power rating indicated on the device.
- Provide the necessary protection against overload and short circuit.
- Ensure there is no interference with the wireless connection. Do not install the module in a distribution box, in a metal housing, or in close proximity to large metal objects.
- Always adhere to electrical regulations.
- Qbus is not responsible for any damage resulting from improper handling or misuse of the module.
Installation and wiring
-
Installation
Place the QWZ-REL02/230 in a suitable fireproof and dry enclosure, such as a junction box or connection box. There should be at least 10mm of free space around the module to ensure it can adequately dissipate heat.
ATTENTION! Ensure that you pair the module with the QWI/ZB before it becomes inaccessible!
-
Power Supply
The module operates at a voltage of 100Vac-240Vac and must be protected by a two-pole automatic circuit breaker with a maximum of C6A. Strip approximately 5mm of insulation from the conductor and screw the conductor into the N-L connectors. Connect the first load to Q1, the second to Q2. If desired, push buttons can be connected to inputs S1 and S2.
-
Troubleshooting
If the receiver does not respond to this module:
- Check if the wireless connection in the installation is not disrupted between this module and the QWI/ZB.
- Verify the configuration of the QWI/ZB and if the link with this module is still active.
- Ensure that other wireless devices operating at the same frequency or in close proximity are not interfering with the operation of this product.
- If the distance between the module and the QWI/ZB is too great, you need to bring the module closer to the QWI/ZB to link them.
If the module exhibits undesirable behavior:
- The module switches on or off at the wrong time.
- The relay engages briefly and then disengages automatically.
- The module does not respond to any control even though there is confirmed good reception between the QWI/ZB and this module.
Be sure to try resetting the module and reconnecting it with the QWI/ZB using System Manager III.

Wiring Diagram
![QWZ REL Top top met lampen en drukknoppen]()
Adding a new Zigbee® module to the network is done by clicking the “Address this device” button.
The Wireless interface then goes into 'commissioning mode' and waits for a module to register.
This action is different for each type of module. This is clarified in the text on the next screen:
After operating the module, as mentioned in the text above, it will attempt to pair with the wireless interface. So make sure that it is within the transmission range of the interface or other powered wireless module that is already in the Zigbee® network!
After a while the following screen will appear:
This shows the short address as well as the signal strength (RSSI, which is expressed in dBm). Larger negative numbers indicate a worse signal. Communication is guaranteed between 0dBm and -60dBm. Signals between -60dBm and -80dBm are weaker and signals smaller than -80dBm should be avoided.
When “(---)” is displayed, it means there is no reception.
As long as no I/Os have been assigned to the module and this data has not yet been sent, the test buttons will send a toggle command. With this first test you can check whether both relays switch on and off smoothly.
After you have assigned the outputs and sent all the new data, the test buttons will operate the I/O in the controller. The controller then forwards the data to all linked modules.
After confirmation, the 'Remove from network' button will send the command to the wireless network to disconnect the module from the wireless interface. Even if the module could not be reached, the short address will be removed from the list of connected modules so that the I/Os on that module can no longer be controlled.
