ilding protection with different setpoint for heating and
cooling functions;
• Automatic switching of the operating modes through
presence sensor or window contact;
• Weighted average of two temperature values;

Accessories
A metallic support, the xing screws and the terminal for
connection of the KNX bus line are delivered with the de-
vice. This has to be completed with the following items:
• a square rocker 60 x 60 mm, with set code EK-T1Q-...,
to be lled with the specic colour and material exten-
sion;
• a single plate and a frame, to be ordered separately,
except for the ‘NF (No Frame) version, which do not
require any frame.
Plate
The room temperature controller may be completed by a
square 1-fold plate or by a rectangular 2-fold plate. In both
cases the plate must be necessarily provided with a 60 x
60 mm window for the mounting of the device.
KNX thermostat with temperature, relative humidity and
CO2equivalent sensors, for the independent thermal re-
gulation of a room or a zone. It has to be used in KNX
installations for control of homes and buildings.
Description
The ekinex®EK-ET2-TP... room temperature controller
is a KNX S-mode device for the independent tempera-
ture regulation of a room or a zone in a building. It can
be installed in houses and buildings (e.g., ofces, hotels,
private house, etc.). The room temperature controller is
equipped with 3 sensors: temperature, relative humidity
and air quality (as CO2equivalent). It can also work as a
controller for these 3 parameters, that are available for a
single zone to be managed. Up to 8 LEDs can be con-
gured, in order to display the operating thresholds for the
CO2 equivalent, the activation of the humidication/dehu-
midication functionality and the cooling/heating working
modes. The device is equipped with an integrated KNX
bus communication module and is designed for wall in-
stallation on a ush mounting box. Both the programming
button and LED are located in the front of the device be-
low the rocker, as well as the 3 sensors. The device is
powered by the KNX bus line and does not require any
auxiliary power supply.
Note. The rocker and the frame (when necessary)
for the completion of the device must be ordered se-
parately. For more information on materials, colors
and nishes available, see also the ekinex®product
catalog or browse www.ekinex.com

Frame
The room temperature controller can be completed by a
square 1-fold frame or by a rectangular 2-fold frame of the
ank or form series. The ‘NF (No Frame) versions of the
pushbutton do not require any frame.
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:

Mounting position
For optimum regulation the device has to be preferably
installed on an internal wall at the height of 1.5 m and at
least 0.3 m far from doors. The device cannot be installed
close to heat sources such as radiators or domestic ap-
pliances or in positions subject to direct sunlight. If neces-
sary, for the regulation may be used a weighted average
between two values selected among the following ones:
value measured by the internal sensor, value measured
by a temperature sensor connected to a device input, va-
lue received via bus by another KNX device (e.g. from
ekinex pushbuttons).
Switching, display and measuring elements
The device is equipped with a programming LED, 8 di-
splaying LEDs with lightguides for feedback status and
3 sensors.
Switching elements
• Pushbutton (13) for switching between the normal and
programming operating mode.
Display elements
• White / red LED (4) for indication of the heating mode

Connection of the KNX bus line
The connection of the KNX bus line is made with the ter-
minal block (black/red) included in delivery and inserted
into the slot of the housing.
Characteristics of the KNX terminal block
• spring clamping of conductors
• 4 seats for conductors for each polarity
• terminal suitable for KNX bus cable with single-wire
conductors and diameter between 0.6 and 0.8 mm
• recommended wire stripping approx. 5 mm
• color codication: red = + (positive) bus conductor,
black = − (negative) bus conductor
Commissioning
For commissioning the device the following activities are
required:
• make the electrical connections as described above;
• turn on the bus power supply;
• switch the device operation to the programming mode
by pressing the programming pushbutton located on
the front side in the area for the mounting of the ro-
ckers. In this mode of operation, the programming LED
is turned on;
• download into the device the physical address and the
conguration with the ETS®program.
At the end of the download the operation of the device
automatically returns to normal mode; in this mode the
programming LED is turned off. Now the bus device is
programmed and ready for use.
Dimensions [mm]
Warning! In order to supply the KNX bus lines use
only KNX bus power supplies (e.g. ekinex EK-AB1-
TP or EK-AG1-TP). The use of other power supplies
can compromise the communication and damage
the devices connected to the bus.
!
Warning! The electrical connection of the device
can be carried out only by qualied personnel. The
incorrect installation may result in electric shock or
re. Before making the electrical connections, make
sure the power supply has been turned off.

Annex 1. Installation
The EK-ET2-TP... room temperature controller comes with
an integrated KNX communication module. It is suitable
for mounting into a ush-mounting box, either round (t)
or square (u), provided with xing holes 60 mm apart.
It can also be installed into a rectangular wall mounting
box (v) 3-seater according to the Italian installation
standard provided with xing holes 83,5 mm apart.
Each thermostat is delivered with its metal support (i, k)
which, in case of necessity, can also be ordered sepa-
rately. A plastic adapter and a terminal block complete
the supply.
The thermostat must be nished off with an operation
surface (rocker), a plate with 60 x 60 mm window and a
frame. The rocker (i) is available in a square shape, in
plastic material and in three different colours.
Each device has integrated eight displaying LEDs with
lightguides for feedback status and 3 sensors.
The square (r, r1) and rectangular (s, s1) frames are
available in two stylish alternatives (form and ank) and
share the same choice of materials, colours and ni-
shings as for rocker.
The ‘NF versions of the device are mounted without
frame and are provided with a side prole in white or
black colour.
