2. Description
The Nunio KNX M-T push button is a touch switch that be universally used for the
KNX building system. It has a monochrome touch display, on which buttons can be dis-
played in various arrangements. The functions of the buttons are defined individually.
As a result, the sensor is extremely flexible with regard to changing requirements
(change of tenant in residential or commercial properties, hotel rooms, etc.).
A temperature sensor is integrated into Nunio KNX M-T push button. An external
temperature reading can be received via the bus and processed with its own data to
create a total temperature (mixed value).
Nunio KNX M-T has a PI controller for heating and cooling. A temperature control dis-
play can also be represented on the screen. The target temperature, mode and, if ap-
plicable, the fan speed can be set there.

3. Installation
3.1. Installation location and preparation
The Nunio KNX M-T push button is installed on a socket. For correct temperature
recording, a wind-tight socket must be used. The casing of the device must not be
opened.
May be installed and operated in dry interior rooms only.
When selecting an installation location, ensure that the measurement results are af-
fected as little as possible by external influences. Possible sources of interference in-
clude:
• 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).
3.2. Connection
DANGER!
Danger due to electrical voltage
(mains voltage)!
• The socket, in which the device is installed, must not contain cabling
with 230 V.
• Observe the regulations and standards applicable to SELV circuits
during installation and wiring of the KNX connection and inputs.

5.3. 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 or wiping over an area, e.g. if
you touch the sensor with the palm of your hand.
Using the area function
The display area of the sensor is divided into four virtual areas, which correspond to
the buttons for the setting “4 buttons”. The virtual areas are independent of the but-
tons shown. They remain the same, irrespective of whether one, two, three or four but-
tons are displayed.
If one of the four areas is touched and another (different) virtual real is touched within
0.2 seconds a key is pressed and another (different) key is touched within one second,
the action set in the ETS is performed for the area operation (See a) and b)). The touch
function is then blocked for 0.5 seconds.
Using the normal key function
If one of the key areas displayed is pressed and no other virtual area is touched within
0.2 seconds, the normal key function is enabled for 5 seconds (See c) and d)). This that
if the 0.2 seconds have passed, different buttons or even the same button can be
pressed multiple times and the normal button function is executed. With each new
touch of a button, the readiness for the normal button function is extended by 5 sec-
onds.

If the area function in the ETS is disabled, the keys can be used normally at any time.
5.4. Temperature controller menu
If the temperature controller of the Nunio KNX M-T is used, a temperature controller
menu can be represented. The temperature controller menu must be activated in the
ETS.
An area °C is then shown at the top right of the button display. Tap it to open the tem-
perature controller menu.

Change target temperature
The target value for the active heating or cooling mode is displayed (Fig. 9b, No. 4)
and can be changed with +/- (Fig. 9b, No. 5+6).
In the device application (temperature controller, ETS), however, it can be spec-
ified that the target cannot be changed for each mode. If the manual modification
of the nominal value is blocked in one mode, the symbol "Manual blocked" is
briefly shown when an attempt is made to modify the value.
The increment and the possible setting range are also specified in the application's
temperature controller. Whether the manually changed values are retained after a
mode change (e.g. Eco mode over night), or if the stored values are reapplied, is also
defined here.
Change mode
Tap the Mode symbol (Fig. 9b, No. 7) in order to display the possible operating modes
one after another. This causes a frame around the symbol to flash. To confirm the se-

lection and activate the displayed mode, remain on the symbol for a little longer. The
frame briefly flashes faster and then disappears. The mode is activated.
The manual selection possibility can be restricted in the device application (tempera-
ture controller, ETS).
A small additional symbol indicates whether heating or cooling is in progress (manip-
ulated variable not equal to zero).
Touch the symbol “Comfort extension” in order to change from Eco mode briefly
into Comfort mode. This allows the user to maintain the nominal comfort value for a
longer time, e.g. when having guests.
The duration of this comfort extension period is set in the ETS. The remaining time is
shown next to the symbol. After the comfort extension period is terminated, the sys-
tem returns to Eco mode.
The comfort extension option may also be blocked in the ETS (symbol does not appear
for selection).
Change fan speed
If Control of a fan (fan coil) is selected in the ETC, touching the fan symbol (Fig. 9b,
No. 8) switches between
AX = Automatic with current level
M0 = Manually switched off
M1 = Manual level 1
M2 = Manual level 2
M3 = Manual level 3
When switching through the levels, a frame around the fan symbol flashes. To confirm
the selection and activate the displayed mode, remain on the symbol for a little longer.
The frame briefly flashes faster and then disappears. The mode is activated.

15 Maintenance
Nunio KNX M-T push button • Status: 25.02.2021 • Technical changes reserved. Errors reserved.
Blocking and jumping back
The button function of the temperature controller display can be pre-
vented because of an active operating mode with priority 1 (e.g. building
protection during window ventilation). This is displayed by the symbol
“Manual change blocked”.
In the application one can specify that the display automatically jumps back to “Sen-
sor” if the display in the temperature controller menu has not been touched for the en-
tered time.
6. Maintenance
Ventilation slits must not be dirty of covered. If required, wipe the device with a soft,
dry cloth.
7. Disposal
After use, the device must be disposed of or recycled in accordance with the legal reg-
ulations. Do not dispose of it with the household waste!
