Push Button with Temperature Sensor
Technical specifications and installation instructions
1. 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:
•1Touch 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:
•OneLED 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.
If the area function in the ETS is disabled, the keys can be used normally at any time.
1.1. Scope of delivery
• Push button in casing
• Base plate
Additionally required (not included in the deliverables):
• Junction box Ø 60 mm, 42 mm deep
• Frame (for insert 55 x 55 mm), compatible to the switch scheme used in the
building
1.2. Technical data
The product is compliant with the provisions of EU Directives.
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.
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 the intended purpose described in this manual. 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 as-
sembled 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 M-T push button is designed for wall installation in a connector
socket (Ø 60 mm, 42 mm deep).
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 interfe-
rence 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).
2.3. Device structure
2.3.1. Casing
2.4. Installation of the sensor
First install the windproof socket with feed line. Seal the inlet tubes as well, in order
to prevent draughts.
Then screw the base plate to the socket and place the switch program frame. Con-
nect the bus cable +/- to the plug (black-red).
Insert the device firmly onto the metal frame using the catches so that the device
and the housing are fixed together. The device has to be inserted such that the bus
terminal faces up (see Fig. 4). This is necessary for a correct temperature measure-
ment and for Cala KNX M2-T and Cala KNX M4-T also for button allocation.
2.5. Notes on mounting and commissioning
Never expose the device to water (e.g. rain) or dust. This can damage the electro-
nics. 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
lasting 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.
5. Disposal
After use, the device must be disposed of or recycled in accordance with the legal
regulations. Do not dispose of it with the household waste!
