in that library. There can be an order of magnitude difference depending on the model of heat pump you use. So, the eQUEST default is at the very low end for ClimateMaster models at least, which does seem too low.</span><o:p></o:p></p>

<p class="MsoNormal">The eQUEST default is .000070 kW/cfm for the HP system type. This is the same as the default for Unit Heaters, and seems really low. It is only 1/4<sup>th</sup> the Appendix G. baseline PTAC/PTHP fan power, which has been criticized as
too low in another [neverending] thread.<o:p></o:p></p>
