Never mind.....
Just got off the phone with Jasco. That's the way the stupid thing is designed. When accent lighting is on, it will not respond to motion and go into full brightness security light mode. I had Heath/Zenith ones previously and they had accent mode and when motion was detected, then they went to full brightness. This is really dumb. With one more switch, they could have had it selectable to either of those two ways of operation.
I can see where in some applications you would not want it to respond to motion when accent lighting is on. Like if you have it in your backyard, like to hang out there after dark with mosquitoes, want the accent lighting, but don't want it going to full brightness when you move. But IMO there are more applications where you want it to respond and go to full on, like when a car pulls up, you go out at night so it lights up the whole area better so you can see, etc. I guess I can live with it though, since it's perfect in all other respects. I'll just set it for 6 hours of accent. Now I have to get another one for the other end of the house, where the roof/soffit slope is greater and see if it can work there too.
