Nunio KNX M-T
Push Button
Technical specifications and installation instructions
Item number 71280
1. 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 displayed 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 exter-
nal 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
display can also be represented on the screen. The target temperature, mode and,
if applicable, the fan speed can be set there.
Communication objects can be linked via AND and OR logic gates.
The switch-sized device has an integrated glass frame, which is backlit by the
screen's lighting. It installed in a switch box.
Functions:
•Display screen with one, two, three or four touch buttons. Icon and text
selectable for each button. Each button can be configured as a switch,
changer, drive (shutter, blind, awning or window with short/long difference),
window, dimmer, 8 or 16-bit encoder or to call/save scenes
•Display lighting with adjustable basic brightness (standby) and operating
brightness. With active operating lighting, the outsides of the frame are
also illuminated.
•Area functionif touched with the hand or when wiping. Can be configured
as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
•Menu for temperature control with +/- buttons (warmer, cooler), target
value display, mode selection button and fan speed setting
• Display lighting adjustable, including switched off in standby mode
•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. Control according to separate setpoints or
basic setpoint temperature. With fan-coil control
•2 AND and 2 OR logic gates each with 4 inputs. Switching events as well
as 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

3. Installation
3.1. Installation location and preparation
The Nunio KNX M-T push button is installed on a socket. For correct tempera-
ture 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.
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).
3.2. Connection
For installation and wiring at the KNX connection, the
provisions and standards applicable to SELV circuits must be
complied with!
The socket, in which the Nunio KNX M-T push button is installed, must not con-
tain cabling with 230 V.
First install the windproof socket with feed line. Seal the inlet tubes as well, in order
to prevent draughts.
Then screw the baseplate to the box.
Connect the KNX databus +/- to the KNX connection terminal (black-red). A brai-
ded sleeve must be used here, which isolates the cables and shields the bus line.
Insert the device firmly onto the metal frame using the catches so that the device
and the housing are fixed together.

5.2. Symbol overview
The following symbols can be selected in the device application (ETS):
5.3. 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 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
buttons shown. They remain the same, irrespective of whether one, two, three or
four buttons are displayed.
If one of the four areas is touched and another (different) virtual real is touched wit-
hin 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 (Siehe 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 wit-
hin 0.2 seconds, the normal key function is enabled for 5 seconds (Siehe 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 exten-
ded by 5 seconds.
If the area function in the ETS is disabled, the keys can be used normally at any ti-
me.
5.4. Temperature controller menu
If the temperature controller of the Nunio KNX M-T is used, a temperature cont-
roller menu can be represented. The temperature controller menu must be activa-
ted in the ETS.
An area °C is then shown at the top right of the button display. Tap it to open the
temperature 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
specified that the target cannot be changed for each mode. If the manual mo-
dification 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 con-
firm the selection and activate the displayed mode, remain on the symbol for a litt-
le longer. The frame briefly flashes faster and then disappears. The mode is activa-
ted.
The manual selection possibility can be restricted in the device application (tempe-
rature controller, ETS).
A small additional symbol indicates whether heating or cooling is in progress (ma-
nipulated variable not equal to zero).
Touch the symbol “Comfort extension” in order to change from Eco mode brief-
ly 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
system returns to Eco mode.
The comfort extension option may also be blocked in the ETS (symbol does not ap-
pear 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 con-
firm the selection and activate the displayed mode, remain on the symbol for a litt-
le longer. The frame briefly flashes faster and then disappears. The mode is activa-
ted.
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. buil-
ding protection during window ventilation). This is displayed by the sym-
bol “Manual change blocked”.
In the application one can specify that the display automatically jumps back to
“Sensor” if the display in the temperature controller menu has not been touched
for the entered 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
regulations. Do not dispose of it with the household waste!
