logic levels and control

I want to use some simple logic for garage door control

If the limit is closed (on) then dont activate the 1 sec timer to close the door.

Basically the door has a contact for open/close/stop, so if it was open it would close on the contact having voltage applied. Similarly it would open if it was closed last - just the general run of the mill garage door control.

I want to create a scene that when I go to bed, I shut down all the lights (currently working OK) and trigger a 1 sec timer to shut the garage door if it is open.

So while I can do this quite easily (using the logoc within the relay itself) if I use a N.C. limit, I cant if I use a more common N.O. limit. Is there a provision to negate levels (eg group x and not group y as opposed to what is now possible group x and group y).

I think I will need a PAC for such a simple action, and that is going to be hard to justify at the moment.

Thanks

Mick
