<P><FONT size=2>Jason,<BR><BR>My bet is that you have a pretty high dT across
the fan (operating at > 5") causing your actually leaving air temperature off
the cooling coil to be less than 50F. I am pretty sure (although it has been a
while) that you can avoid this error and still maintain the same conditions
if you implement a reset schedule on your air temperature (even if you don't
actually reset it), rather than using the cool-min-temp
only.<BR><BR>Regards,<BR><BR></P>

Error<BR><BR>I have an error that says:<BR><BR>In S1 Sys (VAVS), Cooling coil
leaving temperature must be at least 6F higher than entering water
temp.<BR><BR>I have 44" entering CHW with a 12 degree delta T. Cold Air
for the system is set to 54F. I thought with a chiller with a 12 degree
delta T there shouldn't be the above error.<BR>Any
ideas?<BR><BR>-Jason<BR>_______________________________________________<BR>Equest-users
