• Detection and reporting of short-circuit through moni-
toring of the current absorbed by the electrothermal
actuators connected to the outputs
• Detection and reporting of lack of supply voltage on
the electrothermal actuators connected to the outputs
(only if supplied at 230 Vac)

periods of inactivity
• Delayed activation of the outputs (in the range 5-40
s) in order to avoid power-absorption peaks by the
electrothermal actuators

KNX device for control of electrothermal actuators for
zone valves in heating and / or cooling systems. It has
to be used in KNX installations for control of homes and
buildings.
Description
The EK-HE1-TP actuator / controller is an ekinex®KNX
S-mode bus device for the control of electrothermal ac-
tuators and / or motors for zone valves installed on di-
stribution manifolds of installations with radiant panels or
radiators. The 8 output channels use TRIAC to ensure a
noiseless command and a high number of cycles. The de-
vice may work in combination with NC (normally closed)
or NO (normallly opened) actuators and may be used in
installations with 2 or 4-pipe hydraulic distribution; in the
latter application it is possible to interlock the outputs,
completely closing the active valve before the opening of
the coupled valve, avoiding the mix of heating and col-
ling conveying uids. The device is provided with a mem-
brane keypad for manual control of the outputs and LED
indicators for the diagnosis of the operation state and of
alarms triggered by short-circuit of the outputs or power
failure. The device can be congured as simple actuator,
in combination with one or more KNX room temperature
controllers, or as actuator / controller with acquisition of
max 2 temperature values from KNX room temperature
sensors. The device integrates a KNX bus communica-
tion module and is realized for mounting on a standard
35 mm rail. The device is supplied by the KNX bus and
requires an additional 230 Vac or 24 Vac power supply for
the electrothermal actuators.
Functional characteristics
• 8 congurable channels for use with NC (normally
closed) or NO (normallly opened) electrothermal
actuators
• Independent conguration of each output channel
as actuator or actuator / controller for 2 or 4-pipe
systems, channel in parallel or as simple controlled
output through communication object

Mounting
The device has degree of protection IP20, and is there-
fore suitable for use in dry interior rooms. The housing
is made for rail mounting according to EN 60715 in bo-
ards or cabinets for electrical distribution. The correct
mounting is when the KNX bus terminal is located at the
bottom. When installing be sure to leave accessible only
the front panel; all other sides must not be accessible.
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 prole on the
upper edge of the rail (2);
Note. For controlling loads different than electro-
thermal drives and servomotors for zone valve or
loads with rated current higher than the maximum
current, interface relays must be used.
i
Switching, display and connection elements
The device is provided with a membrane front keypad
with signalling LEDs and pushbuttons, programming LED
and pushbutton, a terminal for connecting the KNX bus
line and screw terminals for connecting the power supply
and the outputs.
Note. Use only servomotors for zone valve equip-
ped with stroke-end microswitches.
i

3
• rotate the device towards the rail (3);
• push the locking device upward until it stops (4).
Before removing the device, be sure that power supply
and controlled loads have been disconnected and the bus
terminal has been extracted from its slot. Use a screwdri-
ver to slide down the locking device and remove the de-
vice from the rail.
Connection of the KNX bus line
The connection of the KNX bus line is made with the ter-
minal block included in delivery and inserted into the slot
at the bottom 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

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.
!
Connection of the power supply
The connection of the 230 Vac or 24 Vac power supply is
made with the screw terminals (L, N) located at the top
front of the device.
Characteristics of the terminals
• screw clamping of conductors
• maximum cross section of conductor 2,5 mm²
• recommended wire stripping approx. 6 mm
• torque max 0,5 Nm
Warming! The number of electrothermal actuators
that can be connected in parallel to each output is
limited by the rated current and the starting current
of the device. Carefully check the information on
the technical documentation of the manufacturer of
actuators.
!
Connection of the outputs
The connection of the outputs is made with the screw ter-
minals located at the top front of the device.
Characteristics of the terminals
• screw clamping of conductors
• maximum cross section of conductor 2.5 mm² (single-
wire) or 1.5 mm² (multi-wire)
• recommended wire stripping approx. 6 mm
• torque max 0.8 Nm
To reduce the total starting current, in case of simulta-
neous activation of two or more output channels, it is pre-
ferable to enable the delayed start function during con-
guration via the ETS; in this case, each output channel
is activated with a delay time after the previous channel.
The delay is adjustable in the range 5 ... 40 s and is equal
for all channels.

Disposal
At the end of its useful life the product
described in this datasheet is classied
as waste from electronic equipment
and cannot be disposed together with
the municipal undifferentiated solid
waste.
Conguration and commissioning
Conguration and commissioning of the device require
the use of the ETS®(Engineering Tool Software) program
V4 or later releases. These activities must be carried out
according to the design of the building automation system
done by a qualied planner.
Note. The conguration and commissioning of KNX
devices require specialized skills. To acquire these
skills, you should attend the workshops at KNX cer-
tied training centers.
i
Note. When using in installations with 4-pipe
hydraulic distribution, the outputs have to be used
respecting the coupling between the channel pairs
1A-1B, 2A-2B, 3A-3B, 4A-4B.
i
Conguration
For the conguration of the device parameters the corre-
sponding application program or the whole ekinex®pro-
duct database must be loaded in the ETS program. For
detailed information on conguration options, refer to the
application manual of the device available on the website
www.ekinex.com.

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 of the housing. 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.
Reset of the device
To reset the device remove the bus connection by ex-
tracting the bus terminal from its seat. Keeping pressed
the programming pushbutton, reinsert the bus terminal in
his seat; the programming LED blinks fast. Release the
programming button and remove the bus terminal again;
the reset was carried out. Now you need to address and
congure again the device via ETS.
