<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=263245422-10112005>In
running an old eQUEST model, one that I did not develop so I'm not too familiar
with the strategies used to develop the inputs. I'm getting a boatload of
WARNING messages for curve fits along the following lines:</SPAN></FONT></DIV>

<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=263245422-10112005>Can
you guys advise me about what these messages mean and how to interpret them:
what is the curve number (92.76181), what are the next six values on the first
line, and what is that X, Y, Z all about in the last line? [I'm betting
that last set, MMDDHH: 1 4 1, is the date/time: January 4, at 1 AM in the
morning.]</SPAN></FONT></DIV>

model has quite a few curve fit assignments under the PERFORMANCE CURVE folder
of the Water-Side HVAC frame (33 to be exact). Also, these curves run the gamut
of linear, quadratic, bi-quadratic, and cubic. </SPAN></FONT></DIV>

all but two of the curves the MINIMUM OUTPUT and MAXIMUM OUTPUT values are
-1,000,000 and 1,000,000 respectively. There are two exceptions: the range for
the Variable Speed Drive is 0.10 to 1.00, the range for the HW-Coil-Cap-fdT
curve is 0.01 to 1,000,000.</SPAN></FONT></DIV>
