<font face="Times New Roman, Times, serif">The control zone is the zone
you have picked out of the group of zones where the t-stat is located.
An air side unit will supply conditioned area to all these zones and be
controlled by the T-stat and the conditions in that particular zone.
All the other zones get whatever fraction you have assigned to them
from the air side unit. Sometimes if you have selected a zone not
representative of the group you will get a</font> lot of under or over
cooled hours. One of the ways to get them down is to select a
different control zone out of the group. Depending on why you have
these hours this solution may make a big difference or no difference.
The control zone should be the zone which is the hardest to heat or
cool. It is just trial and error after a good judgment guess. Don't
forget to "save as" to get yourself a copy before you start to play.<br>
