Data sheet STEKHC1TP_EN
KNX devices with function of actuator and tempera-
ture controller for convectors and fan-coil. To be used
in KNX installations for control of homes and build-
ings.
Descrizione
The EK-Hx1-TP series includes three devices ekinex®
KNX S-mode suitable for temperature control
applications. The EK-HC1-TP is used for installations in
2 or 4-pipe hydraulic distribution systems with ON /OFF
control of an electrothermal actuator on a shut-off valve;
control of a 3-speed fan or 0-10 V control of a fan with
brushless motor; this version allows manual control of
the outputs through the membrane pushbuttons. The
EK-HA1-TP version is used for installations in 2-pipe
hydraulic distribution systems with ON /OFF control of
an electrothermal actuator on a shut-off valve and a 3-
speed fan. EK-HB1-TP version is used for installations
in 2-pipe hydraulic distribution systems with ON /OFF
control of an electrothermal actuator on a shut-off valve
and 0-10 V control of a fan with brushless motor.
The devices can be configured as actuators for the
control of a fan and a maximum of two shut-off valves
ON /OFF on the heat exchange coils , in combination
with a room thermostat installed on the KNX network .
The devices can be configured as controllers / actuators
with acquisition of the temperature of a room sensor
KNX or via a sensor installed on the return duct and
connected to one of the analog inputs.

•Membrane pushbutton (5) for switching between the
operating modes forced ( buttons on the front
active ) or automatic ( buttons on the front non-
active )
•Membrane pushbuttons (2) for forcing the fan speed
Thanks to the lever switches located on the front of the
device, the connected loads can be manually controlled
in the absence of voltage on the KNX bus or when the
programming has not yet been carried out.
Note. For the version with membrane keyboard
EK- HC1 - TP , the manual control of the terminal is possi-
ble if the voltage is present both on the KNX bus that the
mains voltage
.
Display elements
•Red LED (7)for displaying the active operating
mode of the device (on = programming, off = normal
operation)
•Red LED (4) for indicating the operating mode ( on
= forced operation , off = automatic)
•Green LEDs for status indication of the speed set
manually for the fan and for the manual setting of
the output valves
•Red LED (10) to give the status of alarm
Mounting
The device has degree of protection IP20, and is
therefore suitable for use in dry interior rooms.
The housing is made for rail mounting according to
EN 60715 in boards or cabinets for electrical
distribution.
The installation is in horizontal position, the correct
position is when the KNX bus terminal is located at the
bottom and the terminals for the outputs are located at
the top.
For the installation of the device on the rail proceed as
follows:
•with the aid of a tool bring the locking device in the
fully lowered position (1);
•place the upper edge of the rear inner profile on the
upper edge of the rail (2);
•rotate the device towards the rail (3);
•push the locking device upward until it stops (4).

Before removing the device, be sure the inputs have
been disconnected and the bus terminal has been
extracted from its slot. Use a screwdriver to slide down
the locking device and remove the device from the rail.
Note. For the EK-HC1-TP version it is recommended that
the installation of the device always ensure the full
accessibility of the front side to allow the operation of the
pushbuttons

•color codification:
red = + (positive) bus conductor
black = - (negative) bus conductor
Warning! In order to supply the KNX bus lines use only a
KNX bus power supply (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.
Connection of the 230 Vac line (all version)
The connection of the line is made with screw terminals
located on the upper front of the device.(Figure A).
Characteristics of the terminals
•screw clamping of conductors
•maximum cross section of conductor 2.5 mm²
(single wire)
•recommended wire stripping approx. 6 mm
•torque max 0.8 Nm
Warning! The electrical connection of the device can be
carried out only by qualified personnel. The incorrect
installation may result in electric shock or fire. Before
making the electrical connections, make sure the power
supply has been turned off..
