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. White LEDs are in-
tegrated in these areas and their behaviour can be adjusted.
A temperature sensor is integrated into Cala KNX T 201/202 Sunblind. An external
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
Additional functions Cala KNX T 201 Sunblind:
•1 operating zone for blinds, awnings, shutters or windows with 2 areas (up/
down with short/long distinction)
Additional functions Cala KNX T 202 Sunblind:
•2 operating zones for blinds, awnings, shutters or windows with 2 areas
(up/down with short/long distinction)
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.

Cala KNX T 201/202 Sunblind push button • Version: 04.10.2021 • Technical changes and errors excepted.
1.0.1. Area function
If the area function in ETS has been activated, another function is available alongside
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 action
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.

ing 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 ad-
dress into the ETS by overwriting the 15.15.255 address or by teaching via the pro-
gramming 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 application,
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.

Threshold value setpoint using a communication object:
Beforehand, enter how the threshold value will be received from the bus. Basically, a
new value can be received, or simply a command to increase or decrease.
During initial commissioning, a threshold value must be defined which will be valid un-
til the first call with a new threshold value. For units which have already been taken into
service, the last communicated threshold value can be used. Basically, a temperature
range is given in which the threshold value can be changed (object value limit).
A set threshold value will be retained until a new value or a change is transferred. The
current value is saved in so that it is retained in the event of a power supply failure and
will be available again once the power supply is restored.
Set the hysteresis independently of the type of threshold value setting.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.

General rules
Decide in which cases nominal values and delay times received per object are to be
kept. The parameter is only taken into consideration if the setting by object is activated
further down. Please note that the setting "After power restoration and programming"
should not be used for the initial start-up, as the factory settings are always used until
the first call (setting via objects is ignored).
For an adequate regulation of the indoor temperature, comfort, standby, eco and build-
ing protection modes may be used.
Comfort when present,
Standby when absent,
Eco as a night-time mode and
Frost / heat protection (building protection) e.g. when the window is open.
The settings for the temperature control include the setpoint temperatures for the in-
dividual modes. Objects are used to determine which mode is to be selected. A change
of mode may be triggered manually or automatically (e.g. by a timer, window contact).
The mode may be switched with two 8 bit objects of different priority. Objects
„... HVAC mode (Prio 2)“ for switching in everyday operation and
„... HVAC mode (Prio 1)“ for central switching with higher priority.
The objects are coded as follows:
0 = Auto
1 = Comfort
2 = Standby
3 = Eco
4 = Building protection
Alternatively, you can use three objects, with one object switching between eco and
standby mode and the two others are used to activate comfort mode or frost/heat pro-
tection mode. The comfort object then blocks the eco/standby object, and frost/heat
protection objects have the highest priority. Objects
„... Mode (1: Eco, 0: Standby)“,
„... comfort activation mode" and
„... frost/heat protection activation mode"
Select the mode to be activated after reset (e.g. power failure, reset of the line via
the bus). (Default).
Then configure a temperature control block using the blocking object.

20 Setting the parameters
Cala KNX T 201/202 Sunblind Push Button • Version: 04.10.2021 • Technical changes and errors excepted
Specify when the current control variables are to be sent to the bus. Periodic trans-
mission is safer if a message does not reach a recipient. You may also set up periodical
monitoring by the actuator with this setting.
The status object reports the current status of the output (0 = OFF, 0 = ON) and may
for example be used for visualisation, or to switch off the heating pump as soon as the
heating is switched off.
Then define the type of setting. Heating and/or cooling may be controlled in two
stages.
General setpoint values
You may enter separate setpoint values for each mode or use the comfort setpoint as
a basic value.
If you are using the controls for both heating and cooling, you may also select the set-
ting "separately with switching object". Systems used for cooling in the summer and
for heating in the winter can thus be switched from one to the other.
If you are using the basic value, only the deviation from the comfort setpoint value is
listed for the other modes (e. g., 2°C less for standby mode).

Cala KNX T 201/202 Sunblind Push Button • Version: 04.10.2021 • Technical changes and errors excepted
The grades for the setpoint changes is predefined. Whether the change remains active
only temporarily (do not store) or remains stored even after restoration of power (and
programming) is determined in the first section of "General controller". This also ap-
plies to a comfort extension.
The controller can be switched from eco mode, i.e. night mode, to comfort mode via
the comfort extension. This means that the comfort setpoint can be maintained for
longer, for example when having guests. The duration of this comfort extension period
is set. After the comfort extension period is terminated, the system returns to eco
mode.
Setpoint Comfort
Comfort mode is usually used for daytime mode when people are present. A starting
value is defined for the comfort setpoint as well as a temperature range in which the
nominal value may be modified.
If setpoint values are entered separately:
If the comfort setpoint value is used as a basis:
If the comfort setpoint is used as the basis, the increase/decrease of this value is indi-
cated.

Setpoint values for frost/heat protection (building protection)
The building protection mode is used, for example, as long as windows are open for
ventilation. Setpoints for frost protection (heating) and heat protection (cooling) are
determined which may not be modified from outside (no access via operating devices
etc.). The building protection mode may be activated with delay, which allows you to
leave the building before the controls switch to frost/heat protection mode.
General variables
This setting appears for the control types "Heating and Cooling" only. This is where you
can decide whether to use a common variable for heating and cooling. If the 2nd stage
has a common variable, this is also where you determine the control mode of the 2nd
stage.
When using the variable for a 4/6 way valve:
0%...100% Heating = 66%...100% variable

9.5.1. Heating control stage 1/2
If a heating control mode is configured, one or two setting sections for the heating
stages are displayed.
In the first stage, heating is controlled by a PI controller which allows to either enter
control parameters or select predetermined applications.
In the second stage (therefore only in case of 2-stage heating), heating is controlled via
a PI or a 2-point-control.
In stage 2, the setpoint deviation between the two stages must also be specified, i.e.
beyond which setpoint undershoot the second stage is then added.
PI controller with control parameters:
This setting allows individual input of the parameters for PI control.
Specify the deviation from the setpoint value at which the maximum control variable
value is reached, i.e. the point at which maximum heating power is activated.
The reset time shows how quickly the controller responds to deviations from the set-
point. In case of a short reset time, the control responds with a fast increase of the con-
trol variable. In case of a long reset time, the control responds somewhat less urgently
and needs longer until the necessary control variable for the setpoint deviation is
reached.
You should set the time appropriate to the heating system at this point (observe man-
ufacturer's instructions).
Now specify what should be sent when the control is blocked. Set a value greater 0
(=OFF) to receive a basic heating stage, e.g. for floor heating.
On release, the control variable follows the rule again.
