1.3 Variant and device parts
•The devices are designed for wall-mounting (A). A conduit box is optional.
–Conduit box: Keep in mind the dimensions of the conduit box!
–Cable conduits on the wall: Keep a distance of 30 mm (from above) /
20 mm (from below) to the base plate (B), so that the device (C) can be
snapped onto the base plate.
•The base plate (B) has screw holes for all common flush-mount boxes.
The screw head height must not exceed 3 mm.
•The device (C) incorporates a KNX / PL-Link plug, a tool plug, and, depending
on the type, sensor element, keys, LCD panel, window for the label.
The cable can be pushed into channels on the rear.
•A KNX plug is enclosed with the devices
The optional metal-reinforced base plate QMX3.MP1 (B1) serves for two purposes:
•It is more rigid so that it does not bend when fixed in the middle with two screws
only (directly over a conduit box or a cavity wall box).
•It has a removable gray foam plate (B2) for mounting on a 68 mm diameter
cavity wall box. The plate compensates for the jutting edge of the box (see
mounting, page 13).
QMX3.MP1 is supplied in boxes with 20 pcs.

The service element functions are described Commissioning, sections 5.2 and 6.2.
The devices are supplied with peel-off adhesive address labels containing the
unique KNX ID as alphanumeric and barcode display.
The address label can peeled off the device during mounting and stuck to a floor
plan or similar. The floor plan thus contains the assignment of KNX IDs and
physical installation location. This greatly simplifies the following steps. In addition,
the procedure serves as the basis for the recommended engineering and
commissioning process. If the adhesive labels are lost, all information is still
available in printed form on the housing.

2 Safety and EMC optimization
2.1 Notes on safety
This section explains general and system-specific regulations for mains and
operating voltages. It includes important information for your safety and the safety
of the entire plant.
Please comply with the following general regulations during engineering and
execution:
•Electrical and mains power ordinances for the given country.
•Other applicable, national regulations.
•Building installation regulations for the given country.
•Regulations of the utility company.
•Diagrams, cable lists, dispositions, specifications, and orders by the customer or
authorized engineering office.
•Third-party regulations, e.g. by the general contractor or building owner.
The electrical safety for building automation and control systems by Siemens is
essentially based on safely separating low voltage from mains voltage.
2.2 Device-specific regulations
Note permissible line lengths and topologies when planning and installing
controllers and field devices featuring KNX bus connection. Make sure the bus
supply complies with the KNX standard.
Do not open the device.
The device is maintenance free. Only the manufacturer can repair the device.
2.3 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.

4.4 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.
4.4.1 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 as control variable of the integrated room temperature controller.
The outdoor temperature received via the KNX bus is only used for indication on
the display and has no effect on the control.
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 as control
variable of the integrated ventilation controller.
The room operator units determine the CO2concentration 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 CO2concentration can be transmitted to other bus
members and serves in KNX as control variable of the integrated ventilation
controller.
The background-lit symbol informs on the current level of CO2in 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 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 for the heating type or cooling 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
