KNX bus communication
6.1
Overview
You can use these instructions to integrate LVLØ to an existing KNX network and to create visualization of
pool equipped with this device. LVLØ Communication objects are divided into three groups. This division is
based on LVLØ mobile application concept.
NOTE:
Group addresses are managed by the manufacturer. No. of group addresses and associations is 51.
6.2
Electrical connection
To enable KNX on LVLØ, connect a Twisted Pair 1 cable which fulfils the KNX requirements (e.g.
YCYM 2×2×0.8 or J-Y(St)Y 2×2×0.8 in TP1 design) to the KNX bus connector. When installing a
standard cable, the following conditions apply.
+ (plus) – Red wire
- (GND) – Black wire
For detailed specification refer to
Connector 17,
connector position details are in section 2.2.2.
NOTE:
Insulated wire cores of sheathed mains cables and KNX TP1 bus cables may be installed next to each
other without any clearance space. A minimum clearance space of 4 mm must be observed between
the insulated wire cores of KNX TP1 bus cables and those of sheathed mains cables. Alternatively,
the wire cores must be provided with an equivalent insulation, such as a spacer or insulation sleeving
(DIN VDE 0110-1, Basic insulation). This also applies to wire cores of other cables that are not part
of SELV/PELV circuits.
Terminating resistor is not required.
6.3
Configuration
This application offers a wide range of setting options in order to execute numerous functions with KNX
pushbutton and controlled KNX devices such as touch panels, etc. Or use pool functions in KNX scenes.
You will find an overview of all the functions, parameters and the related adjustable values in the "Group
addresses parameters and settings„ section.
All 1-bit writable communication objects need to be triggered by 1 bit pulse edge function (send telegram
1 following by 0). If pulse edge “1” / ”0” is detected at the input communication object, the output reacts
to it immediately by changing current state and by sending a status telegram.
KNX BUS needs to be first enabled via LVLØ mobile application in Service section; select Basic setup.
KNX Enabled: <enabled/disabled> Enable or disable the KNX BUS communication.
After performing setup or any changes to this section, click „SAVE SETTINGS” to save configuration to system.
