Functioning
Air2-OTT100W
The knob moves vertically the RIP along the marked positions on the holder. Each
position corresponds to a distance:
These distances are reached when the detector is installed at about 120cm
(height).

Operating principles
The detector works on the combined action of two PIRs and a microwave sensors.
The figures below shows some of most relevant working examples.
