2 Clarification of signs

This manual is amended periodically and will be brought into line with new software

releases. The change status (software version and date) can be found in the contents footer.

If you have a device with a later software version, please check

www.elsner-elektronik.de in the menu area "Service" to find out whether a more up-to-

date version of the manual is available.

Clarification of signs used in this manual

Installation, inspection, commissioning and troubleshooting of the device

must only be carried out by a competent electrician.

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 KNX-

Bus.

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.

5 Installation and start-up

KNX K8 actuator • Version: 26.02.2016 • Technical Changes and Errors excepted.

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

• Operating voltage input 230 V AC L/N/PE

L bridged to IN 1/2, IN 3/4, IN 5/6, IN 7/8

• Actuator on output 8 (OUT 8 | N)

All terminals N or PE of the lower connection strip are bridged internally.
