Technical specifications and installation instructions
1. Description
The Cala KNX T 201/202 Sunblind 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 temperature and solar protection. Whi-
te LEDs are integrated in these areas and their behaviour can be adjusted.
A temperature sensor is integrated into Cala KNX T 201/202 Sunblind. An ex-
ternal temperature reading can be received via the bus and processed with its own
data to create a total temperature (mixed value).
The Cala KNX T 201/202 Sunblind 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 temperature control with 2 areas (warmer, cooler)
•LEDs can be set. All LEDs Off, all LEDs as ambient lighting, all LEDs
individually controllable
•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
•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
•2 AND and 2 OR logic gates each with 4 inputs. 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 as of ETS 5. The product file can
be downloaded from the ETS online catalogue and the Elsner Elektronik website
on www.elsner-elektronik.de in the “Service” menu. There you will also find
the product manual.
1.0.1. Area function
If the area function in ETS has been activated, another function is available along-
side 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 ti-
me.
1.1. Scope of delivery
• Push button in casing
• Base plate
Additionally required (not included in the deliverables):
• Device socket according to DIN 49073
• Frame (for insert 55 x 55 mm), compatible to the switch scheme used in the
building
1.2. Technical specifications
The product conforms with the provisions of EU guidelines.
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 ac-
curacy of the sensor (offset).
When measuring temperature, the self-heating of the device is compensated.
2. Installation and commissioning
Installation, testing, operational start-up and troubleshooting should
only be performed by an authorised electrician.

tructions. Improper use, modifications to the device or failure to observe the ope-
rating instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled condition
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.
2.1. Installation position
The Cala KNX T 201/202 Sunblind push button is installed on a device socket.
May be installed and operated in dry interior rooms only.
When selecting an installation location, 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).
2.2. Composition of the device
2.3. 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.
3. 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.

4. Addressing of the device at the bus
The device is supplied with the bus address 15.15.255. You can program another
address into the ETS by overwriting the 15.15.255 address or by teaching via the
programming button.
5. Display and operation at the device
5.1. Adjust room temperature (using the example Cala
KNX T 201 Sunblind)
Depending on the setting of the "Display mode" parameter in the device applicati-
on, the Cala KNX T 201/202 Sunblind push button displays the current room
temperature value (or mixed value), the target value or the shift in relation to the
basic setpoint. The display can be dimmed and switched off via the bus so that no
value is displayed.
Option A: Display of actual temperature (room temperature)
The current room temperature is displayed. It is not possible to change the room
temperature manually using the +/- buttons.
Option B: Display of target temperature or basic setpoint shift
Depending on the setting, the current target value or the shift relative to the base
setpoint is displayed. The temperature can be changed by touching the +/- buttons.
Target value display (absolute value):
Display of the basic setpoint shift (change compared to the basic setpoint of the
control):
Option C: Display of actual temperature and target temperature/basic
setpoint shift
During normal operation, the current room temperature is displayed. By touching
the buttons, the display jumps to the target temperature or to the basic setpoint
shift, depending on the presetting. Changes with + or - are visible. The display re-
turns to the room temperature if no button is touched for 7 seconds.
Touch the + or - button briefly: The current target temperature (or the basic set-
point shift) is displayed.
Tap +: Increase room temperature
(target temperature/basic setpoint shift is increased).
Tap -: Lower room temperature
(target temperature/basic setpoint shift is lowered).
General:
The step size for the change and the possible setting range are defined in the de-
vice application (ETS). There you can also define whether the manually changed
values are retained after a mode change (e.g. Eco mode overnight) or reset to the
stored values.
The button functions can be locked due to operating mode with priority 1.
6. 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.
7. Disposal
After use, the device must be disposed of in accordance with the legal regulations.
Do not dispose of it with the household waste!
