2-key Tastu glass switch with temperature sensor

• Function description

  The 2-button Tastu with built-in temperature sensor. These switches can be used to control the heating in the room: the temperature sensor measures the room temperature, and via the Qbus controller, valves and/or pumps are controlled based on the measured and desired room temperature. One of the buttons on this switch can be used to select a temperature program – the selected program is indicated by the color of the RGB LED (Manual = White, Frost = Blue, Economy = Orange, Comfort = Red, Night = Green).

  In the Qbus configuration software, a thermostat output can be created, which in turn generates the following 4 outputs:

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

  More information on setting up thermostats can be found in the Qbus System Manager manual.

  The Tastu® switches are made of glass, and they are operated by touching the touch surfaces. These switches are “fingerprint-proof”: a special coating on the glass ensures that fingerprints are not visible on the glass.

  The 2-button Smart Tastu® Switches conceal a convenient second page. When both touch surfaces on the 2-button switch are touched simultaneously, a second page becomes visible where an additional 2 are available. As long as the switch is on the second page, the LEDs will blink (and possibly have a different color; all of this can be configured via the Qbus configuration software) – after 4 seconds without operation, the switch automatically returns to the first page.

  The Smart Tastu® switches are equipped with a bus connector (no polarity). The bus connected to the bus connector provides the Tastu® with power supply and control.

  One touch surface can control 1 output, 2 scenes (long and short press), or through sequences up to 16 scenes.

  Each switch has a unique serial number through which the switch can be programmed. Via the Qbus configuration software (System Manager), an output or a scene can be assigned to a button. If the same output is assigned to different buttons on the same switch, these buttons will operate as if connected in parallel. If the same output is assigned to buttons on different switches, they will operate as if connected in a cross-wiring configuration.

  The switch can also provide interactive feedback on a specific event that occurs. When an alarm is activated, both the function of the button and the color of the LED can temporarily change. For example: the LEDs can blink red, and all buttons become non-functional in case of a burglary alarm, the LEDs blink when the doorbell rings, etc.

Installation and wiring

• Installation

  Install an electrical box (with screws) in the wall. (Installation with claws is possible, but claws are not included with the Tastu®). Screw the supplied metal frame onto the electrical box and ensure that the top is level. Connect the supplied bus cable to the back of the Tastu® (make sure the serial number on the back of the Tastu® is horizontal and readable - that's how it should be placed in the frame. The four connection pins on the back of the Tastu® can be pushed into the corresponding slots of the metal frame. Secure the Tastu® into the metal frame by gently pushing the switch into it. 

• Power supply

  The SWC02T/GX is powered via the 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.

• 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.
  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).

• Temperature sensor

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

  • 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.

  • 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.
