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.
Switching of an output via one or more detectors AND via a push button.

Since a detector will always communicate the exact status of its detection to the configured output, it is not possible to use this same output on multiple modules.
If you want to switch an output via a detector AND via a push button, you must link them through a logic expression.
For example:
IF ( #Hall Detector1 = On
OR #Hall Detector2 = On
OR _Hall Push Button = On )
THEN Hall Lamp = On ELSE = Off

You can find a sample configuration at the following link: Detector_And_Manual.QDB
When uploading the data, a module always displays Err.255 (Module not found)
If Err.255 appears during the programming or verification of a module, this can have several causes:
First, verify whether the serial number was correctly entered as shown on the sticker on the module or its packaging. A serial number always consists of 6 digits or 10 hexadecimal characters (e.g., 0006B01ADE), with the first 4 determining the module type.
Conduct a test through “Utilities/Communication Check”. Enter the last 6 digits of the serial number here and click on “Start Module Test”. If communication with this module is perfect, you should see a nice flat line at 100%. If you see a flat low line, there is no communication. If the line is pulsed, communication is poor. Check whether the bus voltage (+/- 14V) is still correctly reaching the module or check the wiring. Try communicating with the module directly at the controller with 2 short bus wires (without any other connected module) before returning it via our RMA procedure.
Several modules can transmit their serial number:
All SWC variants can be searched via “File/Modules/Search for modules”. After clicking “Start search”, all connected switches will blink blue. Pressing any key on the switch will transmit its serial number.
All modules with a 10-character serial number can be read via “Utilities/Communication Check” if 1 and only 1 module of this new type is connected to the bus, by entering “FFFFFF” as a serial number.

Function description

The smart switches SWC06/YNB and SWC06T/YNB are basic components to be finished with appropriate keys in the BTicino Light Now series. They contain 6 buttons, each with an adjustable RGB LED, and are installed in a BTicino Light Now® mounting frame with at least 3 modules. The SWC06T/YNB is equipped with a built-in digital temperature sensor.
Each SWC06/YNB or SWC06T/YNB is provided with a bus connector with a detachable flexible connection cable. The two-wire bus connected to the bus connector supplies the smart switch with power supply and control. For the connection, the polarity of the bus does not matter.
These switches can be finished with interchangeable BTicino Light Now® keys in white, stone, or black. There are 14 possible combinations with single or double keys with either 1 or 2 functions each. You can select the executed finish in the System Manager III configuration software. When both the lower or both the upper buttons are pressed simultaneously, a second page becomes visible through the change of the color of the LEDs.
You can directly control up to 8 general I/Os, 16 scenes (short & long press) on the SWC06/YNB or SWC06T/YNB via the configuration software SMIII, or via the sequencer up to 8 times 20 of the potential 100 available scenes. A maximum of 8 different I/Os can be assigned for the 1st and 2nd control levels together. If 3 keys each with 1 function are chosen, this means that 3 functions are also available on the 2nd page. If there are 6 functions used on the 1st page, 2 functions are still available on the 2nd page.
The SWC06/YNB and SWC06T/YNB, like all Qbus modules, have a unique serial number that is entered during configuration in the System Manager III configuration software. The switch can also be registered via the “Search for modules” function in SMIII. All programmed data remains internally stored in permanent memory. Each LED indicates feedback on the status of the assigned I/O that is allocated to that button. When the assigned I/O is not active, the LED will be dim (or not) lit; this can be determined in the Qbus configuration software. Also, the color of the LED, the light intensity, and whether or not the LEDs flash collectively on the second page of the switch can be determined via the software. The switch can also provide interactive feedback on a specific event occurring. Both the function of the button and the color of the LEDs can temporarily change. For example: the LEDs can flash red and all buttons become inoperable in case of a burglar alarm, the LEDs flash when the doorbell rings, etc.

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

This is completely explained in our knowledge center.

Button layout

After entering the serial number, creating it from the Wizard, or scanning via "Search for Modules," you must first select the key combination to be used on this module. Qbus supports all combinations of single and double keys with double LEDs or with a single LED at the bottom of a key.
The following selection screen appears:

Double-click the desired key combination to use it.

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:

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.

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.

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.

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).
Additional settings
With this option the following screen appears.
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.
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.

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.
