want the active layer to maintain the zone temperature? You can certainly
use the active layer to maintain the zone temperature (though probably not
perfectly constant with an active layer) using a differential controller (such
as Type 2) that monitors the zone temp and controls the active layer massflow
rate, and you can simply ignore the output temp or override it with an
equation...but why you'd ever do such a thing is not clear to me. Constant
input and output temps for the slab doesn't make any sense, physically. <o:p></o:p></span></font></p>
