2.2 Special functions of the Central Operating Unit Smart
The central operating unit Smart combines a multitude of functions in one device and is particularly
suitable for the Smart Home as a central operating unit. The range of functions includes an
integrated timer for up to 20 channels with holiday function and automatic holiday calculation, a
ventilation control, four direct operating functions for the most important functions such as
"Present", "Central Off", light or blinds, as well as a convenient room temperature controller with
temperature sensor. A code lock with 4-6 digits protects the control panel from unauthorised third
parties, protects an individual push-button function, locks the timer or allows the alarm function to
be safely armed. With the 6 sensor surfaces, all functions can be conveniently operated on the large,
active colour display. Indoor/outdoor temperature, set points, date/time, status information, up to 4
alarm messages and 14 byte text messages are displayed. The 6 status LEDs can be controlled
independently. Furthermore, 6 logic functions are available to process internal and external status
information. The glass control panel Smart is in the design of the glass push-button II Smart. However,
the operating concept of the Smart glass control panel is completely different and does not replace a
glass push-button II Smart. In addition to 4 direct functions, 20 further functions are controlled via an
operating menu. In the operating menu, the function is first selected and then switched. In addition,
the control menu can be used to set the time, holiday control, timer and manual setting of the
holiday mode.

Daily/weekly time switch with astro switch function, holiday function and automatic calculation of
public holidays.
Up to 20 functions/channels can be switched with the integrated timer. The timer is a daily/weekly
timer and has an Astro switch function, a holiday function and an automatic holiday calculation. In
principle, the time switch can be used as a master and supplies all other participants with date/time.
The automatic summer/winter time changeover can be set separately, so that in case the time
changeover is abolished, the normal time can be set again at any time. If a timer is already present in
the KNX system, e.g. the IP interface with time server function (SCN-IP000.03), the time switch can
work with the provided system time in slave mode. Each function/channel can be named individually
and can be controlled via the timer function. Per function/channel 6 switching times are possible.
These can be executed daily or on different days within the week.
In addition to selecting the day and time when a function is to be carried out, additional mode
settings and corresponding conditions can also be defined. In addition to the normal standard
parameter of time, sunrise, sunset, dawn, dusk and random are also available for the mode. In
combination with the conditions time shift (+/- up to 2 hours), at the latest by, at the earliest by, or
at random +/- 10min up to one hour, a multitude of useful functions can be generated. Example see
description Astro switch function
Astro switch function for comfortable blinds / lighting control
The sunrise and sunset times are calculated using the Astro function. Required is the location, either
as location information or by location coordinates, and the date by the timer. The following scenario
is then possible: At sunset, the outdoor lighting is switched on at the right time, the blinds are
lowered in time for the evening before strangers look into the house, and one hour before the blinds
are closed, presence lighting is switched on in the house so that the house looks inhabited even
when absent. At sunrise, the exterior lighting is switched off again early and moves the blinds up in
the morning. In summer, when the sun rises at 5.20 a.m.*, an additional condition determines the
earliest time at which the blinds can be raised, for example 7.30 a.m.. In winter, when the sun rises at
8.30 a.m.*, an additional condition can be used to specify that the blind may move up at the latest by
8.00 a.m., for example. In addition, the presence lighting is switched on and switched off again at
10.00 a.m. when it is bright. This scenario is possible without an external twilight switch and without
a logic module. Various fine tuning of the switching threshold of the sunrise and sunset times is
possible via the Individual settings sunrise/sunset parameter. (* Time examples from June / December of a year)

Holiday function with period activation
The holiday function carries out desired actions during longer periods of absence, for example
lowering the room temperature, lighting scenarios, switching off various functions, etc. The holiday
function is activated via a 1-bit object (on/off) or via a 1-byte object. The 1-bit object is used to
switch the holiday function on or off at different times, while the 1-byte object is used to activate the
holiday function for a fixed period, e.g. 7 days. The status object outputs the remaining days.
With the automatic holiday calculation, holidays can also be enjoyed during the week
The automatic calculation of public holidays can be parameterized individually for all countries. For
Germany and Austria the public holidays of all federal states are preconfigured. Further individual
dates can be added. The holiday event can actively influence the timer. No action or holiday like
Sunday can be set. If the holiday is during the week and the settings are set to holiday like Sunday,
the blinds will move up later during the week and you can start the holiday a little later. (Later time
setting on Sunday assumed). The hot water is also set to get up later, the time of the circulation
pump is also moved back and supplies hot water at a later time when it is needed.
Time function on external display
The timer can send the time telegram cyclically every minute. This enables time displays to be
realized on displays which do not have their own clock function.
4 Direct operating functions
Four direct operating functions are available on the first page of the Central Operating Unit. These
can be executed individually or in groups. Here, important functions such as switching, dimming,
value, scenes, blinds or operating mode changeover can be executed directly. Especially central
functions such as central off, presence, standby or light corridor can be implemented optimally.
20 Operating functions via menu / time switch
In general, a maximum of 24 functions can be managed via the Central Operating Unit Smart. Four
direct operating functions are available, as described above. Twenty functions can be controlled via
manual operating keys and/or the timer. Here, the twenty functions are assigned to a menu with
four function levels (light, blinds, temperature or other). This results in a new manageable operating
concept of the control panel consisting of the upper level with the selection of the function level, the
middle level with the selection of the function, and the lower level with the actual switching function.
Regardless of whether an operating function and/or a timer function is required, it always occupies
one of the twenty functions. The 20 operating functions can be used to control normal switching
functions, blinds/roller shutters, heating/temperature set points, scenes, values and operating
modes. Each time switch function has its own blocking object.

Comfortable room temperature controller with temperature sensor
The functional scope of the room temperature controller ranges from simple heating control to
complete air conditioning of a room. The operating modes heating, cooling and heating and cooling
are available for this purpose. As control parameters, the 2-point control, a switching PI control
(PWM) or continuous PI control can be selected. The room temperature controller supports single
and dual-circuit systems in heating/cooling mode. This makes it possible to control air conditioning
systems with a common pipe system as well as systems with two separate pipe systems for heating /
cooling. The temperature is measured by a temperature sensor hidden in the outer edge of the
control panel, which detects the exact room temperature and sends it to the bus. With the
parameter Sensor internal/external, an additional measurement extension unit can be activated. If,
e.g. in large rooms, the average value of two temperatures is to be formed, the parameter is set to
50% internal / 50% external and an optimum room temperature value is obtained. If the external
sensor fails, an error message is generated and the internal sensor is set to 100%. Likewise, an upper
and lower alarm value can be activated, which outputs a 1-bit message if the value is exceeded or
undershot.
Ventilation control
The integrated ventilation control enables fans to be controlled manually in up to 4 stages, via the
control value of the temperature controller or by means of the temperature difference between
setpoint and actual value. In addition, the day/night function ensures individual adjustment of the
ventilation according to the time of day. For example, the ventilation control runs during the day in
up to 4 stages depending on requirements, while a maximum of two stages are available in night
operation to avoid disturbing noise levels and draughts. An anti-fixing function can be selected to
protect the ventilation system. The behaviour of the locking function can be specifically adjusted.
Code lock
The Central Operating Unit Smart is equipped with a code lock with a digit length of 4-6 digits. The
code lock function can be assigned to one of four possible applications. Either as a device lock, in
which case access to the entire Smart control panel is protected and can only be enabled via PIN
code or an external object. Or as key lock, here a direct operating key is locked and only executed
when the key action has been confirmed with the PIN code. Or for controlling the alarm system, here
the alarm system is activated via a direct operating button, protected via PIN code. The Smart control
panel is then completely locked. It can only be released again and the alarm system disarmed via the
PIN code. And finally to protect the time switch from unauthorised modification.
Status displays
Up to 4 status elements can be displayed in the standby mode of the control panel. These status
elements can be any values of the KNX bus, 14 byte status texts, date/time, internal room
temperature, sunrise/sunset and much more. Via the 14 byte status texts, multimedia information
such as playlist, current song, etc. can be visualised and also scrolling texts can be realised.

Text messages
In addition to the 4 status displays, a further 4 text messages with a maximum of 14 characters can
be permanently set. These 4 text messages are shown on the display as soon as the associated
communication object receives the value 1. The message remains until it is acknowledged by push-
button or a defined time has elapsed. A fifth variable text message can also be activated. Any text
with a length of 14 characters can be sent to this object. When the object is received, this variable
text is shown in the display until it is acknowledged by pressing the key or until a defined time has
elapsed.
Active colour display
The Central Operating Unit Smart has a large, active colour display. This is adjustable in 10 brightness
levels and has an automatic adjustment by a brightness sensor. The display of the background colour
can be set to white or black for day or night operation, depending on customer requirements.
Logic functions
The application of the Central Operating Unit Smart provides a total of 6 logic functions with which
nested function calls can also be implemented, e.g. to enable a scene call in day mode only. The logic
function can process both internal and external status information. This enables, for example, a
second telegram to be triggered when a button is pressed. The logic operations AND, OR and XOR are
available. If the conditions are met, 1 bit / 1 byte values can be sent at the output or scenes can be
called up.
Device Configuration App
The DCA app for the Central Operating Unit Smart is available for free download in the KNX Online
Shop and on the MDT homepage. DCA Apps are supported from ETS 5 on. The file of the DCA App
"MDT_DCA_Operation_Unit_Smart_v10 .etsapp" will be installed as an additional app after the
