I just installed the Leviton occupancy sensor OSC10-M0W.
It came with the OSP20-D0 power pack.
This sensor is described as:
‘The Leviton OSC10-M0W Occupancy sensors is the most advanced sensor available. Combines multi-technology with all-digital architecture. Eliminates false triggering. The result is a trouble-free, “install and forget” solution for lighting control.’
The leviton powerpack that came with the sensor works with 220v power, eventhough most of the material I found on Leviton’s site seems to indicate that 220v is not supported.
So far it seems to work well. Much better than the a previous sensor that I had (a Meiji infrared sensor that was available at Ace hardware). It turns off too quickly – even when people are still in the room and near the sensor. Also it seems to respond faster – turns the light on quicker as soon as presence is detected.
The manuals are downloadable on the net.
