GEWISS KNX occupancy detector also has three HVAC channels as well as its base master
and slave functions (light output). When setting up the parameters, the following options are
available:
1. Detector is operating purely as a master
2. Detector is operating as a master and has additional HVAC channels
3. Detector is operating purely as a slave
4. Detector is operating as a slave and has additional HVAC channels
The slave input of a master affects both light output and the HVAC blocks.
In the following example, the master is fed by two slaves. Slave 2 also has an HVAC
channel. This HVAC channel is also triggered by slave 1. The HVAC channel should not
control any light source, as in this case, lighting regulation is controlled by the master.
