[Equest-users] Control zone.

[Bruce Easterbrook]

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 
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.
