3 Description
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
1. Description
The Cala KNX MultiTouch T push button has touch-sensitive buttons with which
functions can be called up in the KNX building bus system. The glass surface is printed
with areas for setting the light and temperature. LEDs are integrated in these areas and
their behaviour can be adjusted. With Cala KNX MultiTouch T Light/Sunblind, an
area for moving blinds/sunshades (up/down) is added, and with Cala KNX Multi-
Touch T Light/Scenes, an area for calling up scenes (3 scenes).
A temperature sensor is integrated into Cala KNX MultiTouch T. An external tem-
perature reading can be received via the bus and processed with its own data to create
a total temperature (mixed value).
The Cala KNX MultiTouch T has a PI controller for heating and cooling. The setpoint
temperature can be changed using the "+" and "-" touch buttons.
Communication objects can be linked via AND and OR logic gates.
The device is supplemented with a frame of the switch series used in the building, and
thus fits seamlessly into the interior fittings.
Functions:
•Operating zone for light with 3 areas (switching and dimming)
•Operating zone for temperature control with 3 areas (warmer, cooler,
changeover heating/cooling)
• A total of 9 areas, all of which can be assigned either to the intended bus
functions or to other individual bus functions (switches, changeover switches,
dimmers, blinds, awnings, shutters, windows, 8- or 16-bit encoders, scene call/
saving)
•LEDs can be set. All LEDs Off, all LEDs On, active LEDs Always On, all LEDs On
for specific time after button pressed, active LEDs On for specific time after
button pressed. Settable, as to whether LED flashes at block object value = 1.
LED brightness can be pre-set for day and night
•Area function when touching five or more push buttons. Can be configured
as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
•Scene control. 3 scene channels with 5 objects each
•Temperature measurements. Mixed value from own measured value and
external values (proportion can be set by percentage), output of minimum and
maximum values
•PI-controller for heating (one or two-level) and cooling (one or two-level)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature
•4 AND and 4 OR logic gates each with 4 inputs. All switching events as well
as 8 logic inputs (in the form of communications objects) can be used as inputs
for the logic gates. The output from each gate can be configured optionally as
1-bit or 2 x 8-bit
Additional functions Cala KNX MultiTouch T Light/Sunblind:
•Operating zone for blinds, awnings, shutters or windows with 3 areas (up/
down with short/long distinction, driving position)

5 Installation and commissioning
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
1.2.1. Accuracy of the measurement
Measurement variations from permanent sources of interference (see chapter Installa-
tion position) can be corrected in the ETS in order to ensure the specified accuracy of
the sensor (offset).
When measuring temperature, the self-heating of the device is considered by the
electronics. The heating is compensated by the software.
2. Installation and commissioning
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
CAUTION!
Live voltage!
There are unprotected live components inside the device.
• National legal regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when assem-
bled and after conclusion of all installation and operational start-up tasks and only in
the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.
2.2. Installation location
The Cala KNX MultiTouch T push button is designed for wall installation in a con-
nector socket (Ø 60 mm, 42 mm deep).

6 Installation and commissioning
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
May be installed and operated in dry interior rooms only.
Avoid condensation.
When selecting an installation location, please ensure that the measurement results
are affected as little as possible by external influences. Possible sources of interference
include:
• Direct sunlight
• Drafts from windows and doors
• Draft from ducts which lead from other rooms or from the outside to the
junction box in which the sensor is mounted
• Warming or cooling of the building structure on which the sensor is mounted,
e.g. due to sunlight, heating or cold water pipes
• Connection lines and ducts which lead from warmer or colder areas to the
sensor
Measurement variations from permanent sources of interference can be corrected in
the ETS in order to ensure the specified accuracy of the sensor (offset).

8 Addressing of the device at the bus
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
Insert the device firmly onto the metal frame using the catches so that the device and
the housing are fixed together.
2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electronics.
You must not exceed a relative humidity of 95%. Avoid condensation.
After the bus voltage has been applied, the device will enter an initialisation phase last-
ing a few seconds. During this phase no information can be received or sent via the
bus.
3. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming button.
4. Maintenance
Ventilation slits must not be dirty of covered. As a rule, it is sufficient to wipe the device
with a soft, dry cloth as required.

16 Setting the parameters
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
6. Setting the parameters
6.1. Behaviour on power failure/ restoration of
power
Behaviour following a failure of the bus power supply:
The device sends nothing.
Behaviour on bus restoration of power and following programming or reset:
The device sends all outputs according to their send behaviour set in the parameters
with the delays established in the "General settings" parameter block.
6.2. General settings
Set the basic properties of the data transmission.
6.3. Buttons
With the Cala KNX MultiTouch T there is a wake function, i.e. if you want to heat or
cool, press "+" or "-" once and wake up the device (this first key press does not change
the settings) - the LEDs light up and you can see the current setting - now you can raise
and lower the temperature with "+" and "-". This function only makes sense if the LED
mode is set to "...". On for a certain time after pressing the button" is set.

Cala KNX MultiTouch T has an area control, i.e. if you touch 5 or more buttons at
the same time, you can activate another function. The value (0 or 1) can be set for the
evaluation of the activation of the surface operation.
Set whether you want to use the screen control.
Press the required button. The menus for the additional settings of the buttons are then
displayed.
For Cala KNX MultiTouch T Light and Cala KNX MultiTouch T Light/
Scenes, the mode of the middle key line is always "3 individual keys".

18 Setting the parameters
Cala KNX MultiTouch T push button • Version: 11.02.2020 • Technical changes and errors excepted
The Cala KNX MultiTouch T Light/Scenes uses buttons 4-6 by default
("Yes").
6.3.1. Switch / dim light
The commands of the upper line of buttons are as follows:
Briefly press upper left button = switch off
Press upper left button long = dim darker
Press top push-button centre = switch over (switch off or switch on)
Briefly press upper right button = switch on
Press upper right button long = dim brighter
Here you can set the time between switching and dimming and whether the dimming
command is to be repeated.
