<P><FONT SIZE=2 FACE="Arial">Hi All,</FONT>
<BR><FONT SIZE=2 FACE="Arial">Does anyone know how to make a FCU cycle ON/OFF based on the zone thermostat setting? I tried choosing the "Fan on mode" to be intermittent in the Fan->Flow parameters tab. When I make the fan to be intermittent, fan is cycling but the supply CFM is no more a constant volume. It is varying the supply CFM. I observed this in the hourly report.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">ASHRAE standard 90.1 requires the fan to cycle to meet the loads during unoccupied hours. How everybody model this in eQuest when you have a FCU system?</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Any suggestions is greatly appreciated.</FONT>
