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.

Technical info for installers

Function description

The Qbus wireless Easywave Interface (QWI/EW) is the link between the Qbus system and compatible wireless participants. It allows you to connect up to 32 Qbus wireless Easywave modules and certain products from other manufacturers that operate with the Easywave protocol to a Qbus system (see annex 1). You can implement this as a wireless extension to the Qbus system and/or transform a conventional wired installation into an intelligent Qbus installation.
This makes it possible to utilize various control options within the Qbus system, both inside and outside the home or building, with applications such as Qbus Control. The module comes with an external antenna so that the antenna can be mounted in an optimal location.
The QWI/EW can even be combined with a QWI/ZB within the same Qbus system. You can use these two different RF systems simultaneously within the same Qbus installation. Zigbee modules are not compatible with Easywave, and therefore not with the QWI/EW, but they can be connected via a QWI/ZB to the same Qbus system where the QWI/EW is also connected. This allows you to combine the benefits of both RF systems within one Qbus system and optionally combine with Qbus wired modules. Connection to the Qbus-bus from a CTD controller is required to use the QWI/EW.
Easywave modules can be linked to the QWI/EW within a range of up to 30m indoors and up to 150m in open fields.
Preferably, you should use the Easywave system mainly for Easywave transmitters such as battery-powered window contacts, input modules powered by battery or mains, hand-held transmitters, wristbands, etc. The Easywave protocol is power efficient, which makes batteries last a long time. The Easywave actuators do not provide feedback of their status, so their actual status within the Qbus system cannot be guaranteed. We recommend using the Qbus Zigbee range for wirelessly controlled actuators. If the status is less critical, Easywave relay modules can also be connected.

General

Safety Instructions
Read the complete manual before installing and activating the module.
ATTENTION
Installation, commissioning, and maintenance of the devices must be carried out by a certified electrician in accordance with applicable legal requirements.
This device is only suitable for DIN rail mounting according to EN50022. It must be mounted in a fire-resistant distribution board with ventilation openings.
Do not open the device. Opening the module voids the warranty.
This module is only compatible with Qbus Easywave participants and the explicitly mentioned participants listed in annex 1 of this technical sheet.

Installation and wiring

Installation

Click the module onto a DIN rail DIN EN50022.
Power supply

The QWI/EB is fully powered by the Qbus bus.
BUS connection

It is recommended to use the Qbus cable or any other cable with a minimum of 2 conductors of 1mm² as the bus cable. The green shielded EIB cable can also be used if the conductors are paired to achieve a minimum cross-section of 2 x 1mm².

Wiring diagram

With Qbus Controller

Each modules has an unique serial number. By this number the System Manager recognizes the modules.

This is completely explained in our knowledge center.

The Qbus Wireless Interface provides wireless communication between Qbus and all 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 memory of the module first. When you send the data of this (empty) module, all previously registered wireless modules will be deleted from the memory.

You can add the new wireless modules via the green + button or via the Wizard new modules. These are also divided into the categories Relay, Switch, Input and Sensor.
Since each module transmits a unique transmission code, all wireless modules must be enrolled to the gateway. In order to cause the least problems, we recommend that you enroll this code before mounting it in its final location. We also recommend that you first enroll all sensors, because they will send out their code when they detect motion. Once this code is known, it will be ignored when enrolling the next module.

You can select or add a bistable I/O as an error address. This will be switched on by the module as soon as an error is reported on one of the wireless modules. Any module that runs on battery will be able to report a low battery. An additional error message will also be generated if a magnetic contact has not sent its status within 24 hours.

After assigning the wireless gateway, the screen of the QWI/EW will look like this:

After 'Read values', when clicking on a module, the low or completely empty battery status may be shown.
If the battery has been replaced, this error will not disappear automatically. Resetting this individual error is only done by clicking the “Reset Error” button.
