    Can you program the PIR to operate different lighting at different times of the day, for example say from 12am to 7am the toilet light ramps up to 10% instead of 100% ?

    Thanks

    It is quite possible to do this, however not using just the PIR.

    1) You need something which has schedule capability - a touchscreen, wiser, or PAC, in order to do time-based things

    2) You need some way to change the level the light is going to...
    - you can either do this by having the PIR trigger a group which is not directly controlling the light, and then using the logic engine to set the group which does control the light to the appropriate level for the time of day
    - alternatively (and probably more easily), you can use MIN logic in the dimmer. The schedule sets the logic group to the level you want the light to come on at, and the PIR controls the light group. The MIN logic on that channel means the lamp will come on at the MINIMUM of the two levels (the level set by the PIR and the level of the logic group set by the schedule). This is how I do it.

    Sorry DJ,
    Nick obviously didn't mean to give you a run-around, I think he was simply assuming a level or prior knowledge on your part. He gave you the method to achieving what you want, he just didnt elaborate with a step-by-step guide to every detail.
