Parameter setting
KNX K8 actuator
• Status: 18.11.13 • Technical Changes and Errors excepted.
Please note that for a reset time of less than 5 minutes, the pulse with modulation may
only be modified in degrees of 5%.
For all control types
, add the basis time for the valve pulse width modulation. The
basis time determines the signal duration for 100% open, i.e. a basic time of 100
seconds refers to a signal of 30 seconds (followed by 70 seconds without a signal) 30%
opening of the valve.
Select whether you want the control object to be monitored (not for controls via
internal temperature control)
Determine whether the output may also be controlled manually and configure the
manual function and automatic switches.
If manual control is disabled, the keys on the device are not activated. If manual
operation is activated, manual mode becomes active when a key is pressed on the
device or respective information is received via the "Channel X: Auto / Manual" object.
