FAULT FINDING LIST CONTINUED
3.
Unit switches on for no apparent reason -
Check
that the unit is not sited near any air vents or
heating flues. Infra-red patterns are given off by
washing on the line, trees blowing in the wind, high
winds and small animals. Note: To reduce
sensitivity adjust the black adjuster screw, on the
rear of the unit, anti-clockwise.
4.
Unit will not switch off - Are you standing in
the detection zone?
Whilst you are moving in the
detection area the unit will continue to detect. The
light off time is from the last moment detection is
made. Also refer to point 3.
