Heat sources without interference effect
Fig. 62: Sources of interference: heat sources without interference effect
If the temperature changes only slowly, this will not affect the switching behaviour of the
presence detector, e.g. for:
Radiators (distance > 0.5 m)
■
Surfaces heated by the sun
■
EDP systems (computers, printers, monitors)
■
Ventilation systems, when warm air does not flow directly into the detection range of the
■
presence detector.
