We are using Equest to model some chillers that operate in free-cooling
mode at low ambient temperatures. Although we have been able to
characterise the behaviour of the units using the chiller curves we have
been unable to get the code to accept a MIN-COND-T value below 60F. (We
set MIN-COND-T using parametric run keywords).

I understand from some googling that we should be able to force DOE-2 to
ignore the 60F limit if we use a DIAGNOSTICS NO LIMITS commend in BDL,
however I have not been able to successful achieve this.

Can anyone enlighten me as to the syntax for this command and the best
way to import the command into Equest.

Thanks in anticipation of any assistance!
