Your leaving air temp is 45 DegF? Sounds COLD. I had the same error, and
don't have a solution. But what I DID do was raise the LAT 1 DegF. Then
it work. No idea why the error occurred.

Subject: [BLDG-SIM] cooling coil error in eQuest


I have a hydronic cooling coil with EWT of 42 and LWT of 52. My EAT is
80 and my LAT is 45. In eQuest it is set up where the cooling coil LAT
must be at least 6F higher than the EWT. My delta T is only 3F and
therefore I am getting an error in eQuest telling me that the delta T
must be 6F or greater. Has anyone run into this problem and know how to
fix it.

This is the error I have been getting in eQuest: 

 In Support System , cooling coil leaving temperature must be at least
6F higher than entering water temp.


Thanks,

Lori Bokovoy
