<p class="MsoNormal"><span style="color: rgb(31, 73, 125);">Kelsey’s right – in detailed
mode such efficiency measures entered in wizard mode get split into fan energy
(kW/CFM) and heating (EIR/HIR) & cooling (EIR) efficiencies. If entering
values for heating/cooling efficiency – pay mind to whether fan energy is included
in your EER figures (it usually is), and follow Kelsey’s advice to zero out the
fan energy if so. </span></p>
