Take your fan out of the air stream - it is included in the temperature
difference and if you have large fan energy it can represent another couple
of degrees F.

Subject: [Equest-users] Error - System Type 8 - VAV or PIUs.
There is an error that has come up while simulating a 6 lakh sq. ft. bldg.
"cooling coil leaving temperature must be at least 6F higher than entering
The CHW temp is 44 F and I have tried varying the zone supply temperature
from 52 to 60 F. But no luck. The air side system here was PIU or VAV.
However, when I model the same with an FCU at the air side. No error
Any clues why such strange behavior and how to resolve it?
Thanks in advance
