3 Description
KNX K8 actuator • Version: 26.02.2016 • Technical Changes and Errors excepted.
1. Description
The KNX K8 actuator offers eight internal temperature regulators and eight output
channels for controlling heating or cooling systems. The temperature regulators can
control both the outputs on the KNX K8 and other climate control system on the KNXBus.
In automatic mode, the temperature regulators are set at nominal temperatures for
different modes. This way, it is easy to switch between the modes, comfort, standby,
eco and building protection. The switch is made via an object e. g. via a manual switch,
time switch or sensor switch outputs in the KNX-System.
The buttons on the device allow for direct manual switching of the connected systems.
LEDs show whether the output channel was manually operated or is running in an
automatic mode.
Functions:
• 8 internal, independent temperature regulators with automatic controls
for the heating and cooling controls (one or two step heating and cooling)
• 8 output channels (230 V AC, 8 Watt per output) with pulse width modulation
control (PWM) for actuators
• Keypad field 8 buttons and status LEDs
Configuration is made using the KNX software ETS. The product file can be
downloaded from the Elsner Elektronik homepage on www.elsner-elektronik.de in
the “Service” menu.

4 Installation and start-up
KNX K8 actuator • Version: 26.02.2016 • Technical Changes and Errors excepted.
The product conforms with the provisions of EU directives.
2. Installation and start-up
2.1. Installation notes
Installation, testing, operational start-up and troubleshooting should
only be performed by an electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components within the device.
• VDE regulations and national regulations are to be followed.
• Ensure that all lines to be assembled are free of voltage and take
precautions against accidental switching on.
• Do not use the device if it is damaged.
• Take the device or system out of service and secure it against
unintentional use, if it can be assumed, that risk-free operation is no
longer guaranteed.
The device is only to be used for its intended purpose. Any improper modification or
failure to follow the operating instructions voids any and all warranty and guarantee
claims.
After unpacking the device, check it immediately for possible mechanical damage. If it
has been damaged in transport, inform the supplier immediately.
The device may only be used as a fixed-site installation; that means only when
assembled and after conclusion of all installation and operational start-up tasks and
only in the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which may occur
after publication of these operating instructions.

2.2. Device connection and design
2.3. Notes on mounting and commissioning
Device must not be exposed to water (rain). This could result in the electronics being
damaged. A relative air humidity of 95% must not be exceeded. Avoid condensation.
After the operating voltage has been applied, the device will enter an initialisation
phase lasting a few seconds. During this phase no information can be received or sent
via the bus.
2.3.1. Buttons and LEDs for the output channels
The buttons on the devices can be deactivated in the ETS (active when delivered).
1) Programming LED and programming buttons (PRG)
2) Bus terminal slot (KNX +/-)
3) Network LED (power)
4) Buttons and LEDs outputs 1-8
5) Sample connection: Per output max. 8 W
