Wiring Sensor Dimmer switch

I have a Cooper VS106D1 Auto On Sensor Dimmer and can't seem to get it wired correctly. It has a red wire, Black, White, & a ground.
I'm just replacing a single pole light switch with two wires for a ceiling light.

I tried wiring Black to Black & white to White (original config.) the LEDS on the switch light up and seem to do thier thing but the lights don't come on.
Also tried Black to Black & Red to White - which would seem to be correct- but none of the LEDs light up on the switch.
Nothing seems to work.
I'm attaching the diagram for the sensor, in case someone can help me figure this out!
Thanks,
Kent

 

It sounds like you have a switch loop. A switch loop only has 2 wires (ignore the green or bare for this), a constant hot on the white and the switched hot on the black. Your switch requires a neutral which you do not have at the switch.
