Description
The ekinex®room temperature controller is a KNX S-mo-
de device for the independent temperature regulation of
a room or a zone in a building. In combination with one
or more KNX actuators, the room temperature controller
is able to control the heating and cooling emission of a
series of terminal units for the thermal exchange (such
as radiators, fan-coils, oor and ceiling radiant panels,
etc.). The device is provided with a LC-display with adju-
stable backlight, a sensor for temperature measuring and
two freely congurable inputs for the connection of e.g.
window contacts or temperature sensors. The device is
equipped with an integrated KNX bus communication
module and is designed for wall installation on a ush
mounting box. For controlling the room temperature con-
troller functions the integrated 2-fold pushbutton is used.
It is provided with four LED for each channel programma-
ble e.g. as status feedback or orientation nightlight. The
device is powered by the KNX bus line and does not re-
quire any auxiliary power supply.
EK-EQ2-... versions
The EK-EQ2-... versions are provided with a relative hu-
midity sensor and additional functions that use the physi-
cal value measured by the sensor.
Versions and accessories
The device has to be completed with a set of 2 square ro-
ckers specic for the room temperature controller; depen-
ding on the version, a square frame of the form or ank
series may be necessary. A metallic support, the xing
screws and the terminal for connection of the KNX bus
line are delivered with the device.
Note. Rockers and frame (when necessary) for the
completion of the device must be ordered separa-
tely. For more information on materials, colors and

Device operation
The device can be congured to operate as a stand-alone
device (local control) or slave device (control via bus).
Using as a stand-alone device
The control is carried out locally with the two rockers on
the front side of the device. During the conguration it is
possible to enable selectively the available functions. De-
pending on the conguration done with ETS, it is possible
to:
• change temporarily the setpoint of the current operating
mode;
• display an information sequence;
• control a ventilation terminal device;
• change the setpoint values for the operating modes
comfort, standby and economy;
• adjust the intensity of the backlight;
• display the physical address and the rmware release
of the device;
• change the heating/cooling mode (seasonal changeo-
ver).
Using as a slave device
The control is carried out remotely by another KNX de-
vice acting as a supervisor that sends to the thermostat
via bus the operational parameters: e.g. setpoint values,
operating modes or seasonal modes. The possibility of
changing locally the operational conditions, received via
bus by the master device, are limited in comparison to
the use as a stand-alone device and are indicated on the
display by the symbol M (Manual). In this case, the ope-
rating parameters of the room temperature controller can
be changed centrally at the master device.

Seasonal operating modes
The device allows the control of the room temperature for
both modes of operation of the thermal system: heating
and cooling. If a 4-pipe hydraulic distribution is present,
the device can be congured so that the switching betwe-
en heating and cooling modes is done automatically for
the same room and in the same day, if the central system
provides simultaneously warm and cold conveying uids.
The active mode of the system is displayed by an appro-
priate symbol.

Rockers
The symbols on the rockers are predened and cannot be
modied. The areas marked by the symbols + (plus) and -
(minus) allow the change of the temperature setpoint, the
fan speed or to select a setting, while those marked by the
 symbols allow e.g. the displaying of a sequence of
information, the change of the operating mode, the venti-
lation control, the seasonal changeover (heating/cooling)
or the access and conrmation a setting change.

3
The device has four operating modes with setpoint values
to be set independently for the operation in heating and
cooling. The setpoint values as well as the using during
the day of the various operating modes depend on a num-
ber of specic factors such as the building type, the use
of the room, the individual perception of heat and cold,
the ‘inertia characteristic of the room terminals, etc. and
should be carefully considered with the planner of the he-
ating system, the customer and the user.
Comfort
The comfort operating mode is generally set when people
occupy continuously a room.
Standby
The standby operating mode is set in case of absence
of short duration from the room. This mode provides a
small attenuation of the temperature compared to comfort
mode; the attenuation assumes a different direction de-
pending on the seasonal mode setting (lower temperature
for heating, higher temperature for cooling).
Economy
The economy operating mode is set for example in case
of prolonged absence from the room, during the night
hours, etc. and provides an bigger attenuation of tempe-
rature larger than the standby mode.
Building protection
The building protection operating mode is provided with
a temperature threshold; when exceeded, warm or cold
conveying uid is requested to the thermal generator to
avoid potential damages to the building (equipment, fur-
nishings, devices) caused by too low (frost protection) or
too high (overheating protection) internal temperatures.
The building protection function is effective only when the
thermal generator (boiler or chiller) is regularly operating.
If congured and connected to a window contact, the
device automatically switches to the building protection
mode at the window opening and switches back to the
previous mode at the window closing.
Mounting position
For the temperature control function the value of the room
temperature may be measured by the temperature sen-
sor integrated in the device, by another KNX temperature
sensor, by a temperature sensor connected to one input,
or be calculated as a weighted average value of two dif-
ferent sources.
Note. If the device is in the building protection
mode, when the temperature exceeds the threshold
setting, the valve of the hydraulic circuit is opened
even if the fan is switched off.
i
Symbol Fan operation
Switched off mode (OFF): the fan is switched off
and the regulation can not activate it, indipendently
from the the difference between the measured tem-
perature and the current temperature setpoint.
Automatic mode (A): the fan speed is automatically
regulated depending on the difference between the
measured temperature and the current temperature
setpoint.
Manual mode: the fan speed is manually forced
to the level corresponding to the number of bars
switched on (from 1 to 5).
1,50 m
min 0,3 m
Changing operating mode
If the device is congured to operate as a slave, the set-
ting of the operating mode is done via bus by another
KNX device with supervising function (such as a timer or
a centralised control and visualisation unit) of the building
automation system. The only change of operating mode
enabled manually is the recalling of the comfort mode
for a congurable time interval with ETS. If the device is
congured for stand-alone operation, the change of the
operating mode is done manually using the rockers for
the control of the room temperature controller functions.
Ventilation control
The device allow the control of the ventilation function.
The regulation may be continuous or stepwise (max 3
speed levels).
If the temperature value measured by the integrated sen-
sor is used, for an optimal temperature control the device
must be installed taking care of:
• installing the device on an inner wall of the room at a
height of about 1.5 m from the oor;
• not shielding the device with curtains, furniture or other;
• verifying that from the duct connected to the wall box
does not come airows that might affect the temperatu-
re measurement;
• avoiding the installation close to heat sources (such as
domestic appliances or lighting devices), pipes for the
distribution of hot or cold water and terminal devices for
heating and cooling;
• avoiding the installation where the device may be
subject to direct sunlight through glass surfaces.
If these conditions can not be satised, it is appropriate to
use a weighted average value between two temperature
values measured in the same room according to the dif-
ferent possibilities offered from the device (temperature
sensor connected to an input or a KNX temperature sen-
sor). If a second temperature value can not be measured,
it is also possible to correct the value measured by the
sensor integrated in the device using the appropriate of-
fset parameter in the ETS application program.
Mounting
The device has degree of protection IP20, and is therefo-
re suitable for use in dry interior rooms. The installation of
the device requires the following steps:
a) x the metallic support (f) with the screws supplied (e)
on the wall box (g);
b) if required, snap a square frame (d) of the form or ank
series, inserting it from the rear of the device (b) ;
c) connect the sensors or the contacts required to the
4-poles screw terminal block on the rear of the device;
d) insert the terminal for the bus (red/black), previously
connected to the bus cable, in its slot on the rear side

4
(see also: “Connection of the KNX bus line”. At this
point it is recommended to carry out the commissio-
ning of the device (see also “Conguration and com-
missioning”) or at least the download of the physical
address;
e) install the device (b) on the metallic support (f) throu-
gh the spring system, tightening then the two screws.
Mounting the device follow also the indication TOP (ar-
row tip pointing up) on the rear side of the device;
f) snap the two rockers (a) onto the device for the opera-
tion of the room temperature controller.
The device can only be mounted on a round or square
wall ush mounting box with 60 mm distance betwe-
en xing holes. If necessary, the metallic support for
mounting on the wall box can also be ordered separately
using the code EK-SMQ.
Switching and display elements
The device is equipped with a backlighted LC-display,
2 mechanisms for rockers mounting, 4 programmable
LEDs for each channel, a programming LED and a pro-
gramming pushbutton.
Switching elements
• Pushbutton (3) for switching between the normal and
programming operating modes
• Mechanisms (8) for room temperature control functions
to be completed with 2 square rockers
Display elements
• LC-display (1) with digits and symbols for displaying the
operating conditions of the device
• Red LED (4) for indication of the active operating mode
(on = programming, off = normal operation)
• Eight freely programmable LEDs with lightguide (5);
e.g. as status feedback or as orientation nightlight
Measuring elements
The devices is provided with two sensors:
• temperature sensor (not visible, positioned behind the
passage 7);
• relative humidity sensor (6).
Temperature sensor
The integrated temperature sensor measures the tempe-
rature value in a range from 0 °C to +40 °C with a re-
solution of 0.1 K. The measured value can be corrected
by the environmental inuences by means of an offset
parameter. In order to avoid that too rapid temperature
uctuations negatively affect the regulation process, an
acquisition lter can be set. If necessary, for the regula-
tion can be used a weighted average between the value
measured by the integrated sensor and another tempera-
ture value measured in the room by a temperature sensor
connected to one of the inputs of the device or received
via bus by another KNX device. The value measured by
the sensor can be sent on the bus.
Relative humidity sensor (only for EK-EQ2-TP-...)
The measurement of the relative humidity of the room air
mass signicantly extends the functions of thermal regu-
lation and allows to increase comfort and safety of ope-
ration. In combination with the HVAC system, the device
allows to perform a real building climatic control indepen-
dently for each room or zone, adding to heating and co-
oling of the possibility of controlling the dehumidication
and humidication of the rooms. The value measured by
the sensor can be sent on the bus..
Note. Programming pushbutton and LED are ac-
cessible from the front side of the device. The de-
vice addressing may be easily carried out after the
assembly of the frame, removing the rockers. Once
the addressing has been carried out, the device
conguration can be later downloaded without pres-
sing the programming pushbutton.
