<P></P>> Does anyone know if there is a way to bypass or ignore this error? <BR>> I've worked on a few projects recently where we've been able to get <BR>> close to <FONT color=crimson><STRONG>a 46 degree LAT from an AHU with 42 degree water</STRONG></FONT>. Not a big deal I <BR>> guess, but it would be nice to be able to be only 4 degrees above CHW <BR>> temp. <BR>> <BR>> GHT Limited <BR>> James Hansen, P.E., LEED AP <BR>> Senior Associate <BR>> 1010 N.
