1. Description
The KNX eTR 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 integrated in these areas and their behaviour can be adjusted.
A temperature sensor is integrated into KNX eTR 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 KNX eTR 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.
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 KNX eTR 201 Sunblind:
• 1 operating zone for blinds, awnings, shutters or windows with 2 areas
(up/down with short/long distinction)
Additional functions KNX eTR 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 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.

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.

1.1.1. 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

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.

2.2. Installation position

The KNX eTR 201/202 Sunblind push button is made for wall mounting. The
device can be mounted directly on plaster or on a socket (Ø 60 mm).
May be installed and operated in dry interior rooms only.
Avoid condensation.
When selecting an installation location, please ensure that the measurement re-
sults are affected as little as possible by external influences. Possible sources of in-
terference 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).
