Hi Everybody,<br><br>Does anyone understand the heating EIR curves used
for PTACS in Equest? It is the "DX-Heat-EIR-fEDB&OAT" curve. I
calculated the curve using excel (see attached spreadsheet) and found as
the outside air gets colder the efficiency of the heating curve
increases. Does that make sense to anyone?<br>
<br>Thanks in advance,<br><br>Lee
