color:#1F497D'>I’ve played around with it in the past, and in my
experience you will not get accurate lighting behavior if you place the sensor remote
from the space whose lighting is being controlled. It’s not fresh
in my mind, but I believe if you look up the help entries regarding those
sensors you’ll find eQuest handles them in a way that interacts directly with
its location in relation to the surfaces and fenestrations on the interior of
the space in question.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>In short, if you wish to control lighting with daylight sensors
in a 2-story space, it <u>must</u> be a single space/volume. It sounds now
like you are trying to pull this off from the DD-wizards… I think your
options are more limited there. You might try (1) adjusting the
upper-level LPD to account for the ground level lighting, or (2) making the
multi-story space a separate shell wrapped by the other(s)… the latter is
something I’ve done in the past but I’d recommend the detailed edit
fix I suggested below as a relative time/headache-saver. <o:p></o:p></span></p>

light sensor to sense day light coming from the skylights and control light
