Re: I can handle this one
Yeah, but a lot of design-people forget there needs to be a bit of hysteresis built-in.
I used to have a client who were tenants in Danfoss London offices (they that have some knowledge of these things, but perhaps not so well-acquainted with the prevailing weather here). The back of the building was equipped with motorised sun-blinds which were activated by photo-electric sensors. Sometimes the staff became quite mesmerised by the ceaseless closing and opening of the blinds.
