Oh, I think I get this. Since the sensor doesn't trigger if it is on the limit, only outside the limit, you have to set up which is the OK state. Still a little confusing but I guess there is no way to automatically know if an indicator is supposed to be Off or On when it's in it's good state? Tim.
