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 Qbus Wireless Zigbee Interface (QWI/ZB) is the link between the Qbus system and compatible wireless participants. It allows you to connect up to 30 Qbus wireless Zigbee modules and certain products from other manufacturers that operate with the Zigbee protocol to a Qbus system (see annex 1). This can be realized as a wireless extension on the Qbus system and/or to transform a classic wired installation into a smart Qbus installation.
This makes it possible to utilize various control options within the Qbus system, both inside and outside the home or building, with, for example, the Qbus Control application. The module comes with an external antenna, so the antenna can be mounted in an optimal location.
The QWI/ZB with its Zigbee network can even be combined with a QWI/EW within the same Qbus system. You can use these two different RF systems in a single Qbus installation simultaneously. The Easywave modules are not compatible with Zigbee, and therefore not with the QWI/ZB, but you can connect them via a QWI/EW to the same Qbus system to which the QWI/ZB is connected. This allows you to combine the advantages of both RF systems within one Qbus system and optionally combine with Qbus wired modules. To use the QWI/ZB, connection to the Qbus bus from a CTD controller is required.
The Zigbee modules that are powered transmit the signal of another Zigbee module, allowing commands to and from the QWI/ZB to be transmitted via a network of Zigbee modules. This can greatly extend the distance to the QWI/ZB or circumvent objects that obstruct a direct signal. Each QWZ module has its own range. Battery-powered Zigbee participants generally have a limited range, but their signal can be relayed by powered participants. Participants powered via the grid have a greater range. Check the technical datasheet of the Zigbee participants to be connected to know their range. Indicative distances are listed in this datasheet.
Because the Zigbee protocol is a bi-directional communication, applications within the Qbus wireless Zigbee range are possible, such as multizone heating control with wireless thermostats, energy measurement, and more. You can choose to apply the wireless range in the context of "aging in place," creating atmospheres, energy management, security…

Wiring Diagram

With Qbus Controller

This Qbus Wireless Interface provides wireless communication between Qbus and all Zigbee® wireless Qbus modules.

First of all, add the serial number of this module in the list of modules. If this module has already been programmed in another project, it is important to clear the module's memory first. When you send the data from this (empty) module, all previously registered wireless modules will be deleted from memory.

You can add the new wireless modules via the green + button or via the New Module Wizard. These are also divided into the categories Relay, Sensor and Energy.

Because each Zigbee® module can and may only communicate with its own wireless network, all ZigBee® wireless modules must be addressed to the wireless interface.
When replacing a QWI/ZB with a new one, it is not possible to continue using the existing configuration. ALL wireless modules will have to be re-addressed into the network.

After assigning the wireless interface, the QWI/ZB screen will look like this:

Qbus System Manager III Manual Update 04 2025 pdf image 427

Adding a new Zigbee®-module to the network can be started by clicking on "Address this device”.
The Wireless interface goes into ‘commissioning mode’ and waits for the module to assign.
Every module can have a different way to assign. The action will be explained on each commissioning screen.

Zigbee® Niko 552-7200x switches

Also wireless Zigbee® Niko switches can be assigned to a QWI-ZB

Likewise as the QWZ-REL02/230, this module can be connected in a similar way

After addressing the wireless switch, an I/O or a scene can be assigned to each key.
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.
Zigbee® Niko 552-7210x relais with push button

Likewise as the QWZ-REL02/230, this module can be connected in a similar way

On the module, an I/O with ON/OFF operation or a heating contact of a thermostat address can be assigned to each relay.
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.
ATTENTION:
If you use a push button from this module, it will immediately switch the corresponding relays and also transmit this status to the CTD. I/Os of the Timer type (1, 2 and 3) are also turned ON or OFF.
When the I/O controls an output contact of a thermostat address (heating, cooling, etc.), the button on the module may not be used. This will damage the thermostat setting!

Likewise as the QWZ-REL02/230, this module can be connected in a similar way

This module then controls the I/O assigned in the first frame and will also transmit its power measurement to the set I/O (universal type). This has a measuring range up to 3.68kW.

If the device that is plugged into this has a much smaller maximum power and if you wish to adjust the graph on the Cloud, you can do this via the 'Properties' button:

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.
