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., offices, hotels,
private house, etc.). The room temperature controller is
equipped with 3 sensors: temperature, relative humidity
and air quality (as CO equivalent). It can also work as a
2
controller for these 3 parameters, that are available for a
single zone to be managed. Up to 8 LEDs can be confi-
gured, in order to display the operating thresholds for the
CO equivalent, the activation of the humidification/dehu-
2
midification 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 flush 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.
i
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

Main functional characteristics
The common features to all versions are documented as
follows:
• Temperature, relative humidity and air quality (CO
equivalent) measuring through the integrated sensors,
with possibility of sending the read valued on the bus;
• Two-point (ON/OFF) or proportional (PWM or conti-
nuous) room temperature regulation;
• Seasonal modes: heating and cooling with possibility of
either local or via bus seasonal changeover;
• Operating modes: comfort, standby, economy and bu-
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;
• Dew-point temperature computation;
• Temperature regulation (measured and setpoint, as
°C), relative humidity (measured and setpoint in per-
centage), air quality (as CO
in ppm), alarms and errors (with alphanumeric coding);
• Relative humidity thresholds setting;
• CO equivalent thresholds setting;
2
• Floor temperature limitation and antincondensation (for
radiant panels);
• Delayed start of a fan ("hot-start") with time-scheduling
or depending on the water temperature measured at
the coil for thermal exchange.
Other characteristics
• Plastic casing for wall mounting
• Integrated temperature, relative humidity and air quality
(CO equivalent) sensors

• Protection degree IP20 (according to EN 60529)
• Classification climatic 3K5 and mechanical 3M2 (accor-
ding to EN 50491-2)
• Pollution degree 2 (according to IEC 60664-1)
Technical data
• Power supply 30 Vdc from KNX bus line
• Current consumption < 13 mA
• CO output values: 400 ÷ 60000 ppm

Environmental conditions
• Operating temperature: −5 ... +45°C
• Storage temperature: −25 ... +55°C
• Transport temperature: −25 ... +70°C
• Relative humidity: 95% not condensing
Accessories
A metallic support, the fixing 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 filled with the specific 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.
