I installed the PR180 in our kitchen this weekend. The problem is that when set to the auto position the light blinks. It seems to stop after about 5 minutes. This is really annoying. Is this a bad switch?
Unfortunately, it sounds like your lighting is not magnetic rapid start. So it is incompatible. If you use fluorescent lighting, make sure that it is magnetic rapid start or use incandescent or consider a different sensor. Catalog number ODS10 will work with most forms of lighting.
