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.
