Description
The Cala KNX M-T push button has touch-sensitive buttons, with which functions
in the KNX building bus system can be called, such as switch lights and devices,
dim, activate drives, send values, scenarios. A white LED is integrated into each
touch button, the behaviour of which can be adjusted.
A temperature sensor is integrated into Cala KNX M-T. An external temperature
reading can be received via the bus and processed with its own data to create a total
temperature (mixed value).
Communication objects can be connected by 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.
Cala KNX M1-T functions:
•
1 Touch bus button, can be configured as switch, selector switch, dimmer,
blind (position and slats up/stop OR down/stop), shutters (up/down/stop),
awning (in/out/stop), window (closed/open/stop), as 8 or 16-bit encoder or for
scenario recall/storage
Cala KNX M2-T functions:
•
2 Touch bus button, can be configured as switch, selector switch, dimmer,
for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
•
Area function when touching both push buttons. Can be configured as
switch, selector switch, as 8 or 16 bit encoder or for scenario recall
Cala KNX M4-T functions:
•
4 Touch bus button, can be configured as switch, selector switch, dimmer,
for operating drives, as 8 or 16-bit encoder or for scenario recall/storage
•
Area function when touching two or more push buttons. Can be configured
as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
Function of all models:
•
One LED per touch area. On for object value = 1 / Off for object value = 0, On
after pressing button for settable time or always off. Settable, as to whether
LED flashes at block object value = 1
•
Temperature measurements. Mixed value from own measured value and
external values (proportion can be set by percentage)
•
2 AND and 2 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
Configuration is made using the KNX software ETS 5. The product file can be dow-
nloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the "Service" menu.
1.0.1. Area function
If the area function in ETS has been activated, another function is available alongsi-
de the regular key functions. This is triggered by touching multiple keys, e.g. if you
touch the sensor with the palm of your hand.
Using the area function
If a key is pressed and another (different) key is touched within 0.2 seconds, the ac-
tion set in the ETS is performed for the area operation (See Fig. 1 a) and b)). The keys
are then blocked for 0.5 seconds.
Using the normal key function
If a key is pressed and no other key is touched within 0.2 seconds, the normal key
function is enabled/provided for 5 seconds (See Fig. 1 c) and d)). This is extended
for 5 seconds with each push of the button.

1.2.1. Accuracy of the measurement
Measurement variations from permanent sources of interference (see chapter Ins-
tallation position) can be corrected in the ETS in order to ensure the specified accu-
racy 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.

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.
