DANGER
Risk of fatal injury from electrical current.
The unit may only be installed and connected by
skilled electicians. Observe the regulations valid
in the country of use, as well as the valid KNX
guidelines.
The
push-button plus with room temperature con-
trol unit
(reffered to below as the
push-button
) gives
you four (push-button 2-gang) or eight (push-button 4-
gang) operating surfaces. The keys can be set individu-
ally to perform various functions. Furthermore a room
temperature control unit is integrated, which allows you
to control temperature in various different ways.
Functions of the push-button:
– Switching, toggling, dimming, blind control
– Szenenfunktion
– Communication and disable functions
– Time control with synchronisation, reading external
temperature, fan control
Functions of the room temperature control unit:
– Heating/cooling with 1 controller output
– Heating/cooling with seperated controller outputs
– Heating/cooling with 2 controller outputs
The push-button can directly be connected to the KNX
and is parameterised by the electrical installer via the
KNX-Tool-Software (ETS).

Getting to know the keypad
The push-buttons opposite each other can be config-
ured as either individual push-buttons or a push-button
pair. The push-buttons are programmed with various
functions depending on the pre-setting.
For 4-gang push-button only:
The 4-gang push-button is equipped with an IR receiver,
with which you can control the push-button with any IR
remote control. Pressing push-buttons 1-8 on the remote
control activates the function of the corresponding push-
button. Push-buttons 9 and 10 of the remote control have
a direct effect on display push-buttons 9 and 10.
In order for the integrated room temperature control unit
to work in the best way, you should keep in mind the fol-
lowing when selecting the right installation side:

Note for the electrician
Make sure that you note the settings you have
made in the ETS which are important for the user
in the configuration table (see „Pre-settings ta-
ble“), because not all parameters that can be set
are shown in the display of the push-button.

CAUTION
The device could become damaged.
Before removing the push-button, check whether
it is secured with protection against theft. Always
remove the protection against theft before remov-
ing the push-button.
Opening the labelling field
Creating labelled foil strips
You can also create and print corresponding foil strip
templates with any layout program.
Size specifications for foils (in mm):
Consult the operating instructions of your printer to find
out which type of foil strips you can print.
|
Only use the coloured foil strips enclosed as the
base, since this ensures that the push-button
LEDs under the labelling field can shine through.
|
Two versions of coloured foil strips are provided:
one with a recess in the middle for the IR receiver,
and one without a recess. If you want to control
the push-button via an IR remote control, you
have to use the coloured foil strip with recess. Al-
ways only use one of the two coloured foil strips.

When installing the push-button, the electrician defines
various settings that are necessary so you can use the
push-button correctly. Most of the explanations provided
on the following pages depend on these settings. The
electrician enters the settings in question in a table for
you (see table „pre-settings”).
|
If you come across this symbol
when reading,
it means that you can look up the corresponding
value in the table.
With the integrated room temperature control unit, you
can control the temperature in various different ways.
You can read and set important information on the dis-
play:
• Setpoint temperature
• Operating mode (comfort, standby, night, etc.)
• Working day/holiday
• Display mode (setpoint temperature, actual tempera-
ture, date etc.)
• Background lighting
• Setting the time/switching time

Getting to know the control menu
There is a control menu for selecting the individual func-
tions of the room temperature controller.
A rocker is integrated in the cover of the display. It has
three contacts: left, centre and right. With these push-
buttons, you can access the control menu, scroll back-
wards and forwards and change individual values.
Overview of the menu structure
*Long push-button action = approx. 5 s
**Short push-button action = approx. 1 s

If you don‘t press any push-button within a period
of about one minute, the room temperature con-
trol unit automatically returns to the standard dis-
play. The values that were set before the control
menu was opened are restored;
any changes
that you may have made are not saved. Ex-
ception: The temperature is saved directly.
