Taking a quick look at your .ctl file shows that you have different controls set up. Do the other zones work? The main difference seems to be that in zone 1 you are actuating the air point, but sensing a mix of db and MRT. Possibly, this combination does not work (either sense air point and actuate air point or sense db and MRT and actuate mix of convective/radiant flux). The basic controller you are using should generally work fine.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I noticed that the set points you give (typically 16 and 28) are not quite consistent thru ought the zones.
