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
