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

    Thermostat switches feature an invisible digital temperature sensor on the circuit board. All four buttons can still be operated, but an additional thermostat output is now available and can be used to control the heating in the room.

    The thermostat can be controlled manually or via 5 programs. Each program has its own temperature, and the RGB LED is used to indicate which program the heating is on (Manual = White, Frost = Blue, Economy = Orange, Comfort = Red, Night = Green). Four different outputs are immediately generated by the System Manager when creating a thermostat output, and can be used in any relay module:

    1.   Heating = the ambient temperature is lower than the temperature of the selected program, the heating output turns on.

    2.   Turbo = the ambient temperature is lower than the temperature of the selected program by a value higher than a specified limit; the turbo output turns on (boost).

    3.   Alarm = the ambient temperature is more or less than maximum or minimum temperature limits; the alarm output is activated.

    4.   Cooling = the ambient temperature is too high, the cooling output turns on.

    The hysteresis for the heating and cooling output can be set between 0.5°C and 5°C.

    The smart switch SWC04M/xxx in the Niko version contains 4 push buttons, each with a configurable RGB LED, and is mounted in a Niko® 45x45 mounting frame with removable claws and finished with interchangeable Niko® keys in white SWC04/101 or anthracite SWC04/122.

    Every SWC04/xxx is equipped with a bus connector with a detachable flexible connection cable. The two-wire bus connected to the bus connector provides both power supply and control to the smart switch. The bus polarity does not matter for the connection.

    The SWC04, in the Niko® version, are also available in all other Niko colors, but with longer delivery times.

    One button can control 1 assigned I/O, 2 scenes (long and short press), or up to 20 scenes via sequencer mode. When both left or both right buttons are pressed simultaneously, a second page appears where four more buttons are available. In total, one SWC04 can control 8 regular I/Os, 16 scenes, and via the sequencer, 8 times 20 scenes.

Installation and wiring

  • Installation

    Connect the bus cable to the back of the SWC04. Install the switch in a flush-mounted box and secure it by tightening the claws. 

    IMPORTANT: THE BUS MUST NEVER COME INTO CONTACT WITH THE GROUNDING OR A LIVE CONDUCTOR!

  • Power supply

    The SWC04T/X is powered via the bus

  • Second Page

    Press buttons 1 and 2 (top left and bottom) or 3 and 4 (top right and bottom) for a few seconds. The second page is indicated by flashing LEDs and/or a different color of the LEDs (configurable via the configuration software).

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

This is completely explained in our knowledge center.

  • Basic settings

    The switch is essentially the user interface of the system. As with a conventional switch, its operation is very simple.
    Each switch can perform 4 + 4, so a maximum of 8 operations. These operations are simple toggles (ON/OFF), dimming, scene recall, central commands, and anything the system can handle.

    (PS.: This is also limited to 8 for the SWC06/YNB variants. An intelligent switch with 5 keys on the first page can use an additional 3 keys on the second page, and one with 6 keys on the first page can use an additional 2 keys on the second page.)


    To program a switch, follow this procedure:

    When you have entered the serial number of a switch as mentionedin our knowledge center, you will see the following screen appear:

    Qbus System Manager III Manual Update 04 2025 pdf image 300

    It is important that you set the correct type for the Tastu switches. In the drop-down list you can choose from SWC01/G, SWC02/G, SWC04/G or, if equipped with a temperature sensor, SWC02T/G or SWC04T/G

    The screen above is the programming screen of a switch, showing the 4 commands for the switch. These commands are placed so that the top left field (Key 1) corresponds to the top left of the switch when you are in front of the switch, etc.

    Remark: You can verify that the position of the switch is correct by making sure that the serial number on the back of the switch is legible (not upside down).

    To program the switch, click the drop-down box next to the first key; there you can select I/O’s that you have already created, or create a new I/O. Look at our knowledge center for creating I/O’s.
     

    In the drop-down box below the I/O selection window, you can select the mode of the new I/O you want to create. If you have selected an existing I/O, the mode will already be indicated in that box. Look at our knowledge center for a description of the various I/O types you can select.

    Qbus System Manager III Manual Update 04 2025 pdf image 303

    As you can see on the screen below, for each key you can choose the color of the standby LED (off color), as well as the color for the operating state (on color), or even disable all colors completely, with the option above each color.

    It is recommended to use different colors for different I/O’s - e.g. blue for on/off, yellow for dimmers, green for scenes etc. This will make your system easier to use.

    Qbus System Manager III Manual Update 04 2025 pdf image 305

    The UP/DOWN and TEST keys on each key next to the I/O allow you to verify that the selected I/O is operational and that it is indeed the one we want to illuminate on the key in question for this particular switch.

    The properties option takes you to the I/O properties for this key. see Properties for more details.

    As mentioned earlier, these switches have the capacity for 4+4 operations. The other 4 operations can be found on page 2, in the upper part of the window. When you go to this page, an identical screen is displayed with the four keys. The configuration method is exactly the same.

    Qbus System Manager III Manual Update 04 2025 pdf image 306

    ATTENTION!!:
    Switching between the pages is done by pressing 2 keys simultaneously. If you are using BTicino switches: Press the two upper or lower buttons of the switch simultaneously. If you use switches from Niko or the glass switches (Tastu): press the two keys on the left side or the two keys on the right side of the switch. Once this is done, the 4 keys on the 2nd page will be activated. The selection of the 2nd page takes 5 seconds, then the switch returns to the first page. You may want to use the second page of a switch for I/O’s that you do not activate regularly (e.g. shutters).

  • Temperature sensor

    The switches with additional motion detector and/or thermostat sensor have following settings:

    Swc04mt
    • Detecor

    A bistable I/O will be activated when more movement is detected than the 'Activation-trigger'.

    The I/O will be deactivated when after the extension time when there is not more movement detected than the 'Keep-trigger".

    Clicking the 'Scan'-button will visualize the level of movement.

    When "Only if dark"  is checked,  the I/O will only be activated when there is motion AND less light than set up in "Light Level". But when I/O is on, the light level is ignored and only motion will keep the I/O activated.

    • Thermostat

    The thermostat I/O will measure the room temperature and pass it to the controller. All parameters and behaviour of a thermostat can be found in our knowledge center

  • Additional settings

    With this option the following screen appears.

    Qbus System Manager III Manual Update 04 2025 pdf image 308
    • Standard colors for this SWC0x:


    This option allows you to set the standby and operating colors for all LEDs on pages 1 and 2.

    If you click on “Use these colors as default”, the chosen colors will now be used as default. So all switches set to - Default - will use these new colors.

    Clicking "Make this default for ALL SWC0x" will set these colors as default AND will also be assigned to all switches under this project.

    If you want a different standard colour for each kind of I/O, the option “Colours / Mode” can be checked.
    In next screen you can set the default colour/page or a specific colour for I/O’s of type On/Off, Dimmer, Shutter, Other or Scene. When data is sent to the switches, default colours will be sent depending on these settings.

    Qbus System Manager III Manual Update 04 2025 pdf image 309
    • Low light
      With this option the brightness of the LEDs at the OFF position can be adjusted by moving the bar left/right (position 2-10 is recommended).

       

    • With the “Short Flash on Page 2” option, when you use the 2nd page of the switch commands, the LEDs will flash to indicate that you are on page 2.

       

    • The option “TH status visible on LEDs” will reduce the brightness of the LED of the thermostat I/O when the requested temperature has been reached.


      Finally, you will be given the opportunity to select the colors of your choice and use them for the LEDs.

  • Alarms

    Qbus has an option to send warnings when certain situations occur.

    An 'Alarm' can blink the leds, block the inputs, change color or intensity of the leds on intelligent switches.

    SWC Alarm NL

    An SWC can proces up to 8 alarms. They are shown in the list on the left side. In the list on the right side you can see all available alarms.

    When an alarm is activated, the intelligent switch wil executed the settings as setup in 'Properties'.

    One alarm can execute different actions on multiple intelligent switches.

    The default settings of an alarm and an explanation of all alarm functions can be found in our knowledge center.
