I have a C-Bus InfraScan motion sensor which has 4 groups of lights associated with it. Initially I had 3 groups on the InfraScan and these would stay on for 2 minutes when activated (security). My problem started when I added another group (Garden lights) to the InfraScan which I wanted to come on for 6 hrs, using the Sunset Function. Now all 4 groups come on when activated via the motion detection and the last Garden Light group (4) doesn't turn off until 6 hours later, regardless of Sunset. eg When I leave in the morning it is dark and hence the security lights come but so do the garden lights and these stay on all day. What am I doing wrong? How do I stop the garden lights coming on when activated by the InfraScan (motion) but have them come on at Sunset. any help greatly appreciated. Curlyted :confused:
