Switching, display and connection elements
All devices are equipped with a button , a LED pro-
gramming, KNX terminals for connecting the outputs,
additional line voltage and KNX bus line.
The EK-HC1-TP version is equipped with membrane
buttons and LEDs.
1 ) Input and output terminals
2 ) membrane buttons for manual activation of the outputs
3 ) LED status indicators manual output
4 ) LED indicator was manually entered
5 ) Button insertion manually
6 ) Programming button
7 ) LED indication of programming mode
8 ) Terminal KNX bus line
9 ) Terminal for auxiliary power supply 230 Vac
10 ) LED indication of alarm
Command Elements
• Pushbutton (6) for switching between the normal
operation mode and programming
• 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
