3.3 Notes on EMC optimization
When setting up cable ducts, separate strongly interfering cables from susceptible
entities.
• Interfering cables: Motor cables especially from motors supplied by inverters,
energy-supplying cables.
• Susceptible entities: Control cables, low voltage cables, interface cables, LAN
cables, digital and analog signal cables.
• Both types of cables may be in the same cable duct, but in separate
compartments.
• If no three-sided, closed duct with separating wall is available, the interfering
cables must be separated by at least 150 mm from the others or placed in
separate ducts.
• Crossings of strongly interfering cables with possibly susceptible entities must
be at a right angle.
• In exceptional cases, signal and interfering power cables may be run in parallel,
resulting in a high interference risk.
We recommend to generally use unscreened cables. Comply with the
manufacturer's installation recommendations for selecting unscreened cables. In
general, unshielded twisted pair cables have sufficient EMC properties for
technical building applications (including data applications) and do not require
consideration of coupling to surrounding earth.

5.5 Functions
The room operator units with control functions can be integrated in a KNX network.
The control functions for room temperature and ventilation allow for immediate
control of suitable actuators to control heating, cooling, and ventilation.
5.5.1 Measuring
The room operator units measure the room temperature via an integrated sensing
element. The room temperature can be transmitted to other bus members and
serves in KNX S-Mode as control variable of the integrated room temperature
controller.
The room operator units acquire the relative humidity in the room with the aid of a
humidity sensing element integrated in the front module. The relative room
humidity can be transmitted to other bus members and serves in KNX S-Mode as
control variable of the integrated ventilation controller.
The room operator units determine the CO
2
concentration via infrared absorption
measurement (NDIR). The sensor provides exact measurements at all times and
does not require maintenance or recalibration thanks to an integrated, stable
reference light source. The CO
2
concentration can be transmitted to other bus
members and serves in KNX S-Mode as control variable of the integrated
ventilation controller.
The background-lit symbol informs on the current level of CO2 in the room. The
colors green / orange / red of the background lighting indicate good / moderte /
poor air quality. The display can be switched on or off by another bus member, e.g.
switch or timer.

The room operator units can be connected via bus to suitable KNX S-Mode
heating, ventilating, and air conditioning actuators via integrated control functions
for room temperature, humidity, and air quality.
A proven PID controller for heating and cooling is provided to control the room
temperature. The controller supplies a continuous or a pulse-width-modulated PID
signal for one heating and one cooling actuator. The room temperature setpoints
for the two operating modes heating and cooling as well as a blocking object can
be set using the touchkeys and the display, or received from the bus. Changeover
to the operating mode Heating/Cooling is automatic. Preset control parameters,
adjusted to the building type, are available for selection.
The integrated room humidity controller and room air quality controller can be
used for ventilation control. For both controllers, the setpoints can be adjusted
using touchkeys and display, or they can receive up to three switching point values
via the bus.
When the respective switching point is exceeded, up to three control signals and
one quasi-continuous signal to control the ventilation actuators are transmitted to

other bus members. In addition, a signal with the max. control value from both
controllers is available.
The setpoint (from local operation or received vi a bus) directly influences the first
threshold value (see description in sections 6.4.4 and 6.4.6).
Room temperature controller, humidity threshold value, and air quality threshold
switching can be activated or deactivated. As a result, simple sensor function or
room operation is possible also.
Manual room fan control can be enabled, offering three different types for selection
such as single stage, 3 stages, or continuous from 0 to 100 percent. The 9 display
bars change after 10% (display: 10% one bar, …100% 9 bars). For manual
operation, a bar is added on each button press, corresponding to a change of +/11%. This function can be activated or deactivated.
Fan control is independent of the room temperature. When the operating mode is
Auto, the bus command is executed.
The room operating modes can be controlled from Auto to Comfort, Pre-Comfort,
Economy, and Protection. This function can be activated or deactivated.
The presence button allows for manual changeover between Comfort and PreComfort. This function can be activated or deactivated. When activated, the
Comfort extension is not available (key 8, see section 5.4).
When the presence function is deactivated, Comfort can be extended.
Extensions are set between 5 and 120 minutes in ETS.
This function can be activated or deactivated (key 8, see section 5.4.

concentration measurements are influenced by air pressure and temperature.
The lower the air pressure, the lower the measured value. Temperature influence is
corrected automatically. The sensor allows for correcting the determined measured
value to the prevailing average air pressure at the mounting location. To do this,
altitude [m above sea level] must be set. The correction has the following effect on
an uncorrected measured value of 1000 ppm at normal conditions (0 m altitude,
25 °C):

• Function: The sensor determines the CO2 concentration via infrared absorption
measurement (NDIR). The sensor is maintenance free in normal environments,
thanks to the built-in self-correcting ABC (Automatic Baseline Correction)
algorithm. This algorithm keeps track of the sensor’s lowest reading within 8
days and corrects for any drift detected. The sensor also contains selfdiagnostics to assure proper operation during lifetime.
• Use: Normal environments, such as offices, class rooms, hotel rooms, or other
non-permanently occupied areas, typically reach at least once a week the CO
2
concentration of fresh air of 400 ppm. However, exposure to a lowest CO
2
concentration other than fresh air, or incorrect altitude parameter setting, might
result in reduced accuracy and incorrect operation.
• Rough handling during transport, storage or mounting might adversely affect
accuracy during the first days of operation.
• The specified accuracy is reached after 25 days of continuous operation.
8 buttons (individual or button pairs) and related LEDs can be parameterized
individually. See Section 4 for button labels.
Common functions such as switching (On, Off, toggle) or sending of values
(percentage), dimming, or blinds control, 8-bit scene control with/without memorize
are supported.

5.6 Application examples
Below are a few typical application examples for the QMX3.P30, P34, P70 and P74
room operator units.
5.6.1 Room temperature control and operation via QMX3
Key (Possible combination of components)
1. Room operator unit QMX3.P34
2. Presence detector UP 258
3. Motoric valve actuator AP 562/02
4. Window contact S 290
This application is recommended for smaller offices with a single heater.
The room operator unit measures and regulates room temperature and sends the
regulation signal to the valve drive actuator via KNX bus.
In addition, window contacts and presence detectors influence the control behavior
of the room operator unit and increase the room‘s energy efficiency. For example, if
no one is in the room or if the window is open, the radiator valve closes and
reduces the room temperature automatically. Up to 4 window contacts and
presence detectors can be connected via KNX bus.

2. Room sensor QMX3.P70
3. Room operator unit QMX3.P02
4. Presence detector UP 258
5. Switch actuator N 562/11 for fan
6. Shutter/blind actuators N 523/04
7. Universal dimmer N 528/31 with sub-module N 528/41
8. Thermal drive actuator N 605 for up to 6 rooms
9. Thermal valve actuator STA23 (for up to 4 rooms)
This application is especially suitable for rooms with several heaters, e.g. in offices,
lecture halls or conference rooms.
The room operator unit (1) measures and controls the room temperature and
sends the control signal to the thermal actuator (8) via KNX bus. Together with the
integrated room temperature control, the sensor provides for a comfortable room
climate.
The Room operator unit (2) measures the air quality (CO2) in the room, controls
the ventilation as required and thus saves energy and costs. The buttons on the
room operator unit (1 and 3) can be used to control shading, lighting and scenes
for example.
Additional room operator units (1) can also be connected, e.g. in large rooms with
several doors.

Parameters heating / cooling type allow for adapting the
controller to the type of heating / cooling. In addition, the
controller features two control algorithms: one for continuous
mode (0..100%) and one for PWM mode (On/Off). The mode
is selected via parameter "Control value type". The control
value type is identical for all operating modes. In continuous
mode, the associated PWM output is "On" at continuous
control value ≠ 0.
In PWM mode, cycle time and pulse width are adapted to the
type of heating / cooling, the setpoint, and the measured room
temperature. The min. cycle time is 12 minutes, the min. pulse
width is 4 minutes. The continuous control value issues 0% or
100% in this operating mode.

control system
7.1 Engineering
Tool ACS790 is used for engineering in KNX LT E–Mode with devices from the
Synco 700 range. This tool is documented in Service- and Operating software
ACS790 [6].
For ACS790, version 8.23 must be installed at a minimum.
During room operator unit mounting, the address labels can be peeled off the
devices and stuck to a floor plan or similar to show the KNX IDs and the physical
location in one place.
After mounting/installation, the devices are detected after updating the ACS790
device list. The devices can be easily identified in the device list based on the
collected KNX IDs, and the physical addresses can be assigned as planned. As a
result, commissioning requires only very little effort.
7.2 Commissioning
Depending on the environment, both type and number of adjustable parameters
will vary. Prior to commissioning, all devices must be mounted as per the mounting
instructions [2] and connected to bus cabling. If available, pushbuttons and
external temperature sensors must also be connected to the device. Bus cabling
must be tested.
Pushbutton actuation
Meaning
Short (< 0.5 s) Switch over to programming mode or acknowledge
display of a connection test.
No functions are executed when the programming
button is pressed longer (> 0.5 s to 2 s).
Medium-long (>2 s and
<20 s)
Special mode (connection test for Desigo TRA). This
manufacturer-specific function can lock the device for
programming mode for ca. 10 s. In this case, the LED
status indication briefly blinks (orange).
Long (> 20 s)
Reset to factory settings.
LED indication
Meaning
Orange
Feedback on special mode.
Red
Device is in programming mode.
All other indication types are irrelevant for KNX LTE-Mode.
Room sensor QMX3, KNX LTE –Mode controllers, and operator units are
connected to power. Update first the ACS790 device list, then open.
Variant 1 (recommended)
1. Select a room operator unit from the device list via the KNX ID
(KNX-IDs must be collected during mounting).
2. Double-click this line to open the "Address assignment" dialog.

Variant 2
1. Set addressing mode for the room operator unit (briefly press button on
device LED is red).
2. In the ACS790 device list, use "Addressing mode…" to select the
currently active device Enter a physical address in the "Address
assignment" dialog Click "Write".
Enter a physical address and short description for the selected room operator
unit.
Close the "Address assignment“ dialog by clicking "Write…“.
Repeat these steps for all room operator units to be commissioned.
Then: Continue parameterization in ACS790.
The sensor can be operated as both KNX S-Mode and KNX LTE-Mode system at
the same time. To do this, commissioning for both KNX S-Mode and KN X LTEMode is required. All parameters exist only once, i.e. all parameters excepting zone
settings apply to both operating modes and are overwritten by ETS and ACS. For
this reason, do not use ETS to set sending intervals > 15 min. for the measured
values.
Only the sensor values (T, R.F., CO
2
) of the QMX3... devices can be used with
Synco.
To activate them set the zones accordingly in ACS.
ACS settings and ETS settings do not influence each other.
